On 2025-01-16, the 3D printer manufacturer [[:wikipedia:Bambu Lab|Bambu Lab]] announced that future firmwares for their 3D printers would introduce an authorization and authentication protection mechanism for their connection and control, in the name of security. Bambu has stated the following:<blockquote>''"This change is mitigating any risk of remote hacks or printer exposure issues that have happened in the past and also lower the risk of abnormal traffic or attacks."''<ref>https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/</ref><ref>https://all3dp.com/4/bambu-lab-limits-third-party-printer-control-with-new-security-update/</ref></blockquote>
On January 16, 2025, the 3D-printer manufacturer '''[[Bambu Lab]]''' announced that future firmwares for its 3D printers would introduce an authorization and authentication mechanism for printer connection and control, [[Deceptive language frequently used against consumers|in the name of security]].<ref name="firmware-update-introducing-new-authorization-control-system-2">{{Cite web |last=Bambu Kidd |date=2025-01-16 |title=Firmware Update Introducing New Authorization Control System |url=https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/ |url-status=live |archive-url=https://ghostarchive.org/archive/qwL63 |archive-date=2026-03-07 |website=[[Bambu Lab]] Blog}}</ref> The change restricted the use of third-party accessories and slicers such as Panda Touch and OrcaSlicer, and it gated print initiation, motion control, fan and hotend control, AMS configuration, calibrations, remote video, and firmware upgrade behind a Bambu-issued authentication path.<ref name="firmware-update-introducing-new-authorization-control-system-2" /> Bambu Lab also publishes its own slicer, [https://github.com/bambulab/BambuStudio Bambu Studio], under the [[GNU Affero General Public License|AGPL-3.0]],<ref name="bambustudio-license">{{Cite web |title=BambuStudio LICENSE (AGPL-3.0 verbatim) |url=https://github.com/bambulab/BambuStudio/blob/master/LICENSE |website=GitHub |publisher=Bambu Lab |access-date=2026-05-10 |url-status=live}}</ref> while its [[Terms of Service|Terms of Use]] § 3.4 forbid users to modify, copy, reverse engineer, or create derivatives of "the Product."<ref name=":2">{{Cite web |date=2024-04-24 |title=Terms of Use |url=https://bambulab.com/en-us/policies/terms |url-status=live |archive-url=https://ghostarchive.org/archive/vPu9I |archive-date=2026-03-09 |access-date=2025-05-01 |website=[[Bambu Lab]]}}</ref> In April 2026, this authorization system became the basis for a [[Bambu Lab cease and desist against OrcaSlicer fork developer|cease-and-desist demand against a Polish community fork maintainer]] who had restored direct printer control on top of the AGPL source.

=== Potential for Remote Disabling of Printers ===
===Potential for remote disabling of printers===
A significant concern raised by the community revolves around the wording in Bambu Lab's Terms of Service & firmware update announcements. Critics & users argue that the phrasing leaves open the possibility for the manufacturer to remotely disable printers that are not updated to the latest firmware. Specifically, Bambu Lab's documentation states that printers may block "new print jobs" if updates are not applied, which some users interpret as a potential pathway for forced obsolescence<ref>https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/</ref>.
A concern raised by the community revolves around the wording in Bambu Lab's [[Terms of Service]] (ToS) and firmware update announcements. Critics and users argue{{CitationNeeded}} that the phrasing leaves open the possibility for the manufacturer to [[Remote disabling|remotely disable]] printers that are not updated to the latest firmware. Specifically, Bambu Lab's ToS warns that printers may block new print jobs if updates are not applied,<ref name=":2" /> which some users interpret as a potential pathway for forced obsolescence.<ref name="firmware-update-introducing-new-authorization-control-system-2" /> While defenders of Bambu Lab point out that offline modes such as SD-card printing and [[wikipedia:Local_area_network|LAN]]-only setups would remain functional, others point out that the ToS do not explicitly limit this restriction to [[Cloud (service)|cloud]]-based printing. This ambiguity has led to speculation that Bambu Lab could enforce broader limitations, effectively rendering printers inoperable for users who choose not to update.<ref name="theverge-bambu-2025">{{Cite web |last=Hollister |first=Sean |date=2025-01-22 |title=Here's what Bambu will — and won't — promise after its controversial 3D printer update |url=https://www.theverge.com/2025/1/21/24349031/bambu-3d-printer-update-authentication-filament-subscription-lock-answers |url-status=live |access-date=2025-05-01 |website=The Verge |archive-url=http://web.archive.org/web/20251122143504/https://www.theverge.com/2025/1/21/24349031/bambu-3d-printer-update-authentication-filament-subscription-lock-answers |archive-date=2025-11-22}}</ref>


Defenders of Bambu Lab point out that offline modes such as SD card printing & LAN-only setups would remain functional, others point out that the Terms of Service do not explicitly limit this restriction to cloud-based printing. This ambiguity has led to speculation that Bambu Lab could enforce broader limitations, effectively rendering printers inoperable for users who choose not to update<ref>https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/</ref>.
====Editing of initial announcement====
Bambu users were concerned they would not be able to use their printer if they did not install this update, due to the wording of the blog and the ToS.<ref>[[:File:Bambu tos screenshot.png]]</ref> This caused confusion since users report that Bambu's blog post dated January 16, 2025<ref name="firmware-update-introducing-new-authorization-control-system-2" /> includes the FAQ entry:
<blockquote>''What happens if I never upgrade to this firmware?''


=== Debate Over "Bricking" Terminology ===
''You may continue using an older firmware version that does not include the new security updates; however, this means the printers may miss out on important security fixes or bug patches included in newer versions. We highly encourage updating to the latest firmware version for the best experience and enhanced security.''</blockquote>However, '''this was not present on the day of the announcement.''' A snapshot of their webpage from archive.is demonstrates this section did not exist on the day of the announcement, when community members voiced their concerns.<ref name="firmware-update-introducing-new-authorization-control-system-2" /><ref>[[:File:2024-01-16-Firmware Update Introducing New Authorization Control System.pdf]]</ref> Bambu's response to community feedback<ref>{{Cite web |last=@Spaghetti Monster |date=2025-01-20 |title=Updates and Third-Party Integration with Bambu Connect |url=https://blog.bambulab.com/updates-and-third-party-integration-with-bambu-connect/ |url-status=live |archive-url=https://ghostarchive.org/archive/cIejw |archive-date=2026-03-30 |access-date=2025-05-01 |website=Bambu Lab Blog}}</ref> references ''"social media posts spreading baseless allegations and untrue claims about Bambu Lab",'' including ''"Firmware updates will block your printer's ability to print.",'' without mentioning the context for those allegations. The context for those allegations was the lack of inclusion of the ''"What happens if I never upgrade to this firmware?"'' in Bambu's initial announcement alongside their stated terms of service.
The debate has also extended to the definition of "bricking." Some community members assert that if a printer is unable to accept new print jobs without an update, it effectively becomes non-functional and qualifies as being "bricked." Others counter that as long as certain offline functionalities remain—such as SD card printing—the term does not accurately apply<ref>https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/m7sezlg/</ref>.  


=== Community Strategies to Deal with Risks ===
After the edit, the announcement header reads '''Updated: January 17, 2025''' and notes that additional details and FAQs (including the "What happens if I never upgrade to this firmware?" entry) were added.
Users have discussed strategies to avoid possible disruptions, including:
* Operating printers exclusively in offline modes.
* Utilizing LAN connections or VPN setups, yet LAN mode requires authorization now.
* Exploring alternative firmware or third-party scripts to restore full functionality<ref>https://old.reddit.com/r/BambuLab/comments/1i45iy2/bambu_lab_reserves_the_right_to_brick_your/m7t8i7r/</ref>.


== Bambu Lab's Justification and Rebuttal ==
The earliest archive.is snapshot of the announcement, dated January 16, 2025 17:31 UTC,<ref name="firmware-update-introducing-new-authorization-control-system-22">{{Cite web |last=@BambuKidd |date=2025-01-16 |title=Firmware Update Introducing New Authorization Control System |url=https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/ |url-status=live |archive-url=https://ghostarchive.org/archive/qwL63 |archive-date=2026-03-07 |access-date=2025-05-01 |website=[[Bambu Lab]] Blog}}</ref> contains two passages about staying on the old firmware. Under "Important Information for End Users":
Bambu Lab has stated that the authorization system is in place in order to protect against "remote hacks," "printer exposure," and "abnormal traffic or attacks." However, there are several ways to mitigate these risks without the loss of user control that their system causes:
<blockquote>''2. Old Firmware Option: Users who decide to use an older firmware version can still use the previous or new versions of Bambu Studio and Bambu Handy without restrictions.''</blockquote>
Under "Information for OrcaSlicer users":
<blockquote>''1. You can continue using your X Series 3D printer with the older firmware version (which does not include Authorization Features). 2. If you choose to upgrade to the firmware version with Authorization Features, you must download and install Bambu Connect (a printer control software).''</blockquote>
The FAQ section was added after the initial blog post publication and is noted as an update in the announcement header.


* '''The "remote hacks" that were cited as an example in the article seem to be a direct result of the 3D printer vendor not responding properly to a reported security vulnerability in their product<ref>[https://www.bitdefender.com/en-au/blog/hotforsecurity/someone-is-hacking-3d-printers-to-warn-owners-of-a-security-flaw?ref=blog.bambulab.com https://www.bitdefender.com/en-au/blog/hotforsecurity/someone-is-hacking-3d-printers-to-warn-owners-of-a-security-flaw]</ref>. Therefore, in order to get attention, the researcher decided to infect machines and display a harmless message to spread publicity.''' Properly responding to security vulnerabilities, working to patch them quickly, and working with the security community (who would be more than happy to help secure products) would be some ways to prevent this.
===Debate over "bricking" terminology===
* In the article cited about printer exposure, it was done largely due to misconfiguration on the part of users<ref>[https://www.csoonline.com/article/566223/over-3700-exposed-3d-printers-open-to-remote-attackers.html?ref=blog.bambulab.com https://www.csoonline.com/article/566223/over-3700-exposed-3d-printers-open-to-remote-attackers.html]</ref>. Printer exposure can be mitigated by offering more convenient ways to securely expose printers to the internet, so users are not tempted to allow unauthenticated access over the network.
The debate has also extended to the definition of "bricking". Some community members assert that if a printer is unable to accept new print jobs without an update, it effectively becomes non-functional and qualifies as being "bricked." Others counter that as long as certain offline functionalities remain (such as SD-card printing) the term does not accurately apply.<ref name="theverge-bambu-2025" />
* The "abnormal traffic" can be mitigated by steps Bambu has already put in place, as detailed in their own article on the matter<ref>[https://wiki.bambulab.com/en/security-incidents-cloud-traffic?ref=blog.bambulab.com https://wiki.bambulab.com/en/security-incidents-cloud-traffic]</ref>.


The system that Bambu has chosen to implement is overly restrictive and unnecessary, and does more harm than good, as detailed in the rest of this article.
===Privacy policy issues===
Bambu Lab's privacy policy describes that when a user submits a print job through Bambu cloud, Bambu may forward configuration information, printing settings, model picture, plate thumbnails and G-code files (referred to in the policy as "Printing Files"), and when the print history reprinting feature is enabled, may store started times, finished times, and filament consumption.<ref name=":6">{{Cite web |date=2025-03-25 |title=Privacy Policy |url=https://bambulab.com/en-us/policies/privacy |url-status=live |archive-url=https://ghostarchive.org/archive/0XOv5 |archive-date=2026-03-10 |access-date=2025-05-01 |website=[[Bambu Lab]]}}</ref> The privacy policy webpage is not present in the Wayback Machine.<ref name=":6" />


== Issues with LAN Mode Requiring Authorization ==
===Community strategies to deal with risks===
Users have discussed strategies to avoid possible disruptions, including:
*Operating printers exclusively in offline modes.
*Using LAN connections or VPN setups: this requires an access key from the printer (previously, you could use your cloud credentials over LAN).
*Exploring alternative firmware or third-party scripts to restore full functionality.<ref name="theverge-bambu-2025" />


Before recent firmware updates, Bambu Lab printers had the ability to be controlled over LAN without requiring cloud services or authentication with manufacturer. This allowed users to integrate their printers into private networks & maintain full control without having to rely on the manufacturer's server. However, the new authorization system mandates that even LAN-based operations go through an authentication process using Bambu Connect<ref>https://wiki.bambulab.com/en/software/bambu-connect</ref>.
==Bambu Lab's justification and rebuttal==
Bambu Lab has stated that the authorization system is in place in order to protect against "remote hacks," "printer exposure," and "abnormal traffic or attacks". The cited security incidents have specific context:


This change has drawn criticism for many good reasons:
*The "remote hacks" cited as an example in the article followed a reported security vulnerability in a 3D printer product; according to Bitdefender's reporting, the researcher infected machines to display a harmless message in order to publicize the unpatched flaw.<ref>{{Cite web |last=Cluley |first=Graham |date=2024-03-01 |title=Someone is hacking 3D printers to warn owners of a security flaw |url=https://www.bitdefender.com/en-au/blog/hotforsecurity/someone-is-hacking-3d-printers-to-warn-owners-of-a-security-flaw?ref=blog.bambulab.com |url-status=live |archive-url=https://web.archive.org/web/20260216002646/https://www.bitdefender.com/en-au/blog/hotforsecurity/someone-is-hacking-3d-printers-to-warn-owners-of-a-security-flaw?ref=blog.bambulab.com |archive-date=2026-02-16 |access-date=2025-05-01 |website=[[Bitdefender]]}}</ref>
* **Privacy Concerns**: Requiring authentication for LAN mode raises concerns about data being unnecessarily exposed to Bambu Lab's servers, even for local-only operations.
*In the article cited about printer exposure, the hack was carried out largely because of user misconfiguration.<ref>{{Cite web |last=Ms. Smith |date=2018-09-05 |title=Over 3,700 exposed 3D printers open to remote attackers |url=https://www.csoonline.com/article/566223/over-3700-exposed-3d-printers-open-to-remote-attackers.html?ref=blog.bambulab.com |url-status=live |archive-url=https://web.archive.org/web/20260216002556/https://www.csoonline.com/article/566223/over-3700-exposed-3d-printers-open-to-remote-attackers.html?ref=blog.bambulab.com |archive-date=2026-02-16 |access-date=2025-05-01 |website=[[CSO]]}}</ref>
* **Loss of Offline Independence**: Before, users could have entirely offline setups. The requirement for authentication  removes this option unless users revert to older firmware versions, which Bambu does not allow people to do once they have updated.  
*The "abnormal traffic" can be mitigated by steps Bambu has already put in place, as detailed in their own article on the matter.<ref>{{Cite web |title=Summary of Security Incident Responses and Abnormal Cloud Traffic |url=https://wiki.bambulab.com/en/security-incidents-cloud-traffic?ref=blog.bambulab.com |url-status=live |archive-url= |archive-date= |access-date=2025-05-01 |website=[[Bambu Lab]] Wiki}}</ref>

=== Precedents and Comparisons ===
==Issues with LAN mode requiring authorization==
Critics have likened this potential functionality to similar cases in other industries where manufacturers remotely restrict product features. Notable examples include HP's printer firmware updates that rendered third-party ink cartridges unusable and Tesla's software locks on second-hand vehicles. These parallels suggest a broader trend of manufacturers leveraging software to control hardware capabilities post-purchase<ref>https://www.classaction.org/hp-printer-lawsuit</ref><ref>https://www.wired.com/story/tesla-remote-disable-used-car-features/</ref>.

[[File:Bambu Connect App - Lan Device Discovery without Bambu Login.png|thumb|Bambu Connect App - Lan Device Discovery without Bambu Login]]
Bambu Lab printers have the ability to be controlled over both cloud and LAN. This allowed users to integrate their printers into private networks and maintain full control without having to rely on the manufacturer's server while also allowing cloud access. The new authorization system mandates that even LAN-based operations must go through an authentication process using Bambu Connect to retain full control.<ref name="bambu-connect">{{Cite web |[email protected] |title=Bambu Connect (beta) |url=https://wiki.bambulab.com/en/software/bambu-connect |url-status=live |archive-url=https://ghostarchive.org/archive/CVCtK |archive-date=2026-03-30 |access-date=2025-05-01 |website=[[Bambu Lab]] Wiki}}</ref> Full local access is still possible and unchanged for those not using the cloud.


== Implementation Timeline and Requirements ==
This change has drawn criticism for many reasons:
*'''Privacy concerns''': Requiring authentication for LAN mode raises concerns about data being unnecessarily exposed to Bambu Lab's servers, even for local-only operations, though previously, the printer was also connected and could be controlled by the cloud even when sending prints locally.
**Confidentiality required by US Law: this is in conflict with users that have to comply with internal U.S. government classified information handling regulations.{{CitationNeeded}}
*'''Loss of offline independence while also using cloud''': Before, users could have hybrid offline setups. The requirement for authentication removes this option unless users revert to older firmware versions; Bambu Lab initially indicated rollback would not be permitted, though The Verge later reported that users could still downgrade and use LAN access keys while signed into the cloud.
*'''Increased complexity''': The added authentication layer complicates workflows for users who built custom setups or relied on third-party integrations for LAN control while retaining cloud functionality.<ref name=":4">{{Cite web |last=@edlboston |date=2023-01 |title=Full Non-Cloud Based Network Option Needed |url=https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643 |url-status=live |archive-url=https://ghostarchive.org/archive/1ee4F |archive-date=2026-03-30 |access-date=2025-05-01 |website=[[Bambu Lab]] Community Forum |quote=Yes, I know about the LAN mode. But as has been stated by many people, things like the camera will not work, nor will the Handy app. There is no technical reason that these are bound to the cloud. This is the problem and why I titled this FULL Non-Cloud Network.}}</ref>


The authorization system will be rolled out in phases, starting with the X1 series printers. A beta firmware (version 01.08.03.00) was released on January 17th, 2025, with the full release scheduled for January 23rd, 2025. The P & A series printers will get similar updates at an unspecified future date.
*LAN-Only mode in Orca Slicer is implemented by passing API Calls to the installed proprietary Bambu Network Plug-In (unlike BTT and other solutions that did indeed communicate with printer directly via MQTT protocol).
*Plug-In provides controls for Printers "Critical Operations" (as classified by the Firmware Announcement article) and displays these controls within the window of Orca Slicer.
*Using intermediary Plug-In does not manifest as "direct access through network plugin". It is still a Proxy communication, even if user experience is presented as direct communication (same slicer window).
*Bambu Connect moves the Network Plug-In functionality outside of the window of Orca Slicer thus appearing as separate window and presents the appearance of  "indirect" communication channel to the printer.
*While the user experience is different, the flow remains unchanged Orca Slicer slices model -> Orca Slicer Calls API of Bambu Proprietary Software -> Bambu Proprietary Software controls the printer.


To use printers with the new authorization system, users must update multiple pieces of software:
Additionally, Bambu Connect software (downloaded and installed in January 2025, before the backlash response) supports adding LAN-Only printers without requiring Bambu Account authentication, the same behavior as the Network Plugin used in Orca Slicer.{{CitationNeeded}}
* Bambu Studio must be updated to version 01.10.02.64 or higher
* Bambu Handy mobile app must be updated to version 2.17.0 or higher
* The new Bambu Connect application must be installed for using third-party slicers


These software updates are mandatory for users who update their firmware - failing to update all components simultaneously will result in certain printer controls becoming unusable. Users who choose to maintain third-party software compatibility can continue using older firmware versions, though this will not be an option for new printers which will ship with the authorization system pre-installed.
===X1E firmware 01.01.02.00 LAN-mode connection failure===
Newly received X1E printers with firmware 01.01.02.00 will not connect to the Bambu Studio using the Lan only method password. Bambu Studio identifies the un-logged printer but will not allow a connection to the printer. Only after connection / account pairing is done over the Bambu Handy app by giving internet access to the PC and Printer then using the cloud service connection will Lan only communication and login work.<ref>{{Cite web |last= |date=2024-09 |title=Connect X1E to stand-alone computer |url=https://forum.bambulab.com/t/connect-x1e-to-stand-alone-computer/101474 |url-status=live |archive-url=https://web.archive.org/web/20260223033045/https://forum.bambulab.com/t/connect-x1e-to-stand-alone-computer/101474 |archive-date=2026-02-23 |access-date=2025-05-01 |website=[[Bambu Lab]] Community Forum}}</ref>


Bambu Lab states these coordinated updates are necessary because the new authorization system fundamentally changes how the printer validates & accepts commands. The older versions of Bambu Studio & Bambu Handy lack the authentication mechanisms required to interact with printers running the new firmware. The Bambu Connect application was created specifically to provide a controlled interface for third-party software, replacing the previous direct access through network plugins<ref>https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/</ref>.
==Implementation timeline and requirements==
{{outdated/section}}
The authorization system will be rolled out in phases, starting with the X1 series printers. A beta firmware (version 01.08.03.00) was released on January 17, 2025, with the full release scheduled for late January 2025.<ref name="firmware-update-introducing-new-authorization-control-system-2" /> The P and A series printers will get similar updates at an unspecified future date.


== Impact on Third-Party Integration and User Choice ==
To use printers with the new authorization system, users must update multiple pieces of software:<ref name="firmware-update-introducing-new-authorization-control-system-2" />
*Bambu Studio must be updated to version 01.10.02.64 or higher
*Bambu Handy mobile app must be updated to version 2.17.0 or higher
*The new Bambu Connect application must be installed for using third-party slicers


=== Changes to Third-Party Access ===
These software updates are mandatory for users who update their firmware. Failing to update all components simultaneously will result in certain printer controls becoming unusable. Users who choose to maintain third-party software compatibility can continue using older firmware versions, or downgrade the firmware for new printers that ship with the authorization system pre-installed.<ref name="firmware-update-introducing-new-authorization-control-system-2" />
The new authorization system replaces direct network API access with a more limited URL-based interface through Bambu Connect. Third-party software can only interact with the printer by sending specific URL commands to Bambu Connect<ref>https://wiki.bambulab.com/en/software/bambu-connect</ref>. The interface requires three parameters:


* <code>path</code>: The absolute file system path to the 3MF file (e.g., /tmp/cube.gcode.3mf)

The path and name parameters must be URL-encoded using encodeURIComponent or equivalent functions<ref>https://wiki.bambulab.com/en/software/bambu-connect</ref>.


=== Reduced Home Automation Capabilities ===
===Changes to third-party access===
While basic status monitoring remains available (e.g., print progress updates in Home Assistant), the new firmware removes the ability for home automation systems to control printer functions. Users can no longer:
The new authorization system replaces direct network API access with a more limited URL-based interface through Bambu Connect. Third-party software can only interact with the printer by sending specific URL commands to Bambu Connect.<ref name="bambu-connect" /> The interface requires three parameters:
* Start or stop prints remotely via Home Assistant
* Control printer temperatures or cooling
* Automate printer behaviors based on sensor data or events
* Access camera feeds through third-party applications<ref>https://forum.bambulab.com/t/this-new-auth-system-will-make-me-sell-my-printers/135400/9</ref>


=== Permanent Nature of the Update ===
*<code>path</code>: The absolute file system path to the 3MF file (e.g., /tmp/cube.gcode.3mf)
Once a printer is updated to the new firmware, users cannot revert to previous versions that allowed fuller third-party integration. This creates a one-way transition that permanently removes capabilities users had when purchasing their printer. While Bambu Lab presents this as optional for existing users, all new printers will ship with the restricted firmware pre-installed, eliminating user choice entirely<ref>https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/</ref>.
*<code>name</code>: The name of the file (e.g., Cube)
*<code>version</code>: A fixed value of 1.0.0 for compatibility


The manufacturer states this change is required for security, but community members note that many of the security vulnerabilities being addressed stem from Bambu's own cloud-centric design choices rather than inherent risks of local network control<ref>https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12</ref>. The update forces users into Bambu's ecosystem of applications & cloud services, regardless of their preferences or needs for local network automation.

This is a significant post-purchase reduction in functionality for existing owners who bought their printers with the understanding they could use third-party software & home automation tools. The inability to revert these changes, combined with the mandatory nature of the update for new printers, demonstrates how manufacturers can use software updates to unilaterally modify the capabilities of hardware products after purchase<ref>https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/9</ref>.

== Impact on Functionality ==
This interface only allows basic file transfer and print initiation. All other printer-control functions previously available to third-party software are now exclusive to Bambu's own applications. The path and name parameters must be URL-encoded using encodeURIComponent or equivalent functions<ref name="bambu-connect" />.
While some functionality remains unauthenticated like in previous firmware versions (sending status information from the printer over the network, starting a print job using SD cards), the most important features now require authentication through a new closed-source client called Bambu Connect<ref>https://wiki.bambulab.com/en/software/bambu-connect</ref>. These restricted features include:


* Initializing prints via LAN or cloud mode
===Reduced home-automation capabilities===
* Remote video access to monitor prints
While basic status monitoring remains available (e.g., print-progress updates in Home Assistant), the new firmware removes the ability for home-automation systems to control printer functions. Users can no longer:

===Permanent nature of the update===
Once a printer is updated to the new firmware, users can still revert to previous versions.<ref name="theverge-bambu-2025" /> The option still exists to disable the cloud service.


Previously, third-party software such as OrcaSlicer<ref>https://github.com/SoftFever/OrcaSlicer/issues/8063</ref> could interact with Bambu Lab printers via the open-source Bambu Studio and proprietary network plug-ins. While Bambu Connect provides a limited URL-based API to initiate prints, most functionality previously openly available is now restricted to Bambu's ecosystem<ref>https://forum.bambulab.com/t/this-new-auth-system-will-make-me-sell-my-printers/135400/9</ref>.
The manufacturer states this change is required for security, but community members note that many of the security vulnerabilities being addressed stem from Bambu's own cloud-centric design choices rather than inherent risks of local network control<ref name="bambulab-forum-134549/12">{{Cite web |date=2025-01-14 |title=Bambu Studio 1.10.2 Public Beta |url=https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12 |url-status=live |archive-url=https://ghostarchive.org/archive/u4vpc |archive-date=2026-03-30 |access-date=2025-05-01 |website=[[Bambu Lab]] Community Forum}}</ref>. The update forces users into using Bambu Connect middleware if they want to retain limited cloud functionality.


== Communication with OrcaSlicer Developers ==
For users that would want to use a third-party slicer while using their cloud service, Bambu would require those users to download and install Bambu Connect in order to send gcode wirelessly over LAN or over the cloud. While Bambu claims that they were in contact with SoftFever, the developer of OrcaSlicer, as of January 2025, SoftFever did not have any keys for Bambu Connect and the new firmware was only available as opt-in beta at the time.<ref name=":1">{{Cite web |last=@fever_soft |date=2025-01-18 |title=This is definitely a bummer.

==Impact on functionality==
{{outdated/section}}
While some functionality remains unauthenticated like in previous firmware versions (sending status information from the printer over the network, starting a print job using SD cards), the most important features now require authentication through a closed-source client called Bambu Connect<ref name="bambu-connect" />. These restricted features include:


Before the official announcement of the new authorization & authentication, Bambu Lab engaged with the OrcaSlicer development team regarding the changes. This communication has sparked significant discussion within the 3D printing community, particularly regarding its timing, tone, and implications.
*Initializing prints via LAN or cloud mode
*Remote video access to monitor prints
*Controlling motion system, temperature, fans
*AMS settings and calibrations
*Home automation integration beyond basic status monitoring


=== Pre-Announcement Contact ===
Previously, third-party software such as OrcaSlicer<ref name="orca-slicer-issue8063">{{Cite web |date=2025-01-16 |title=FW 1.08.03.00 from Bambu WILL BREAK ORCASLICER for X, P and A series #8063 |url=https://github.com/SoftFever/OrcaSlicer/issues/8063 |url-status=live |archive-url=http://web.archive.org/web/20250708192842/https://github.com/SoftFever/OrcaSlicer/issues/8063 |archive-date=2025-07-08 |access-date=2025-05-01 |website=[[GitHub]]}}</ref> could interact with Bambu Lab printers via the open-source Bambu Studio and proprietary network plug-ins. While Bambu Connect provides a limited URL-based API to initiate prints, most functionality previously openly available is now restricted to Bambu's ecosystem<ref name="bambulab-forum-135400/9" />.
Reports from the OrcaSlicer demonstrate that Bambu Lab provided limited advance notice of the changes that would render their software incompatible with Bambu printers running the new firmware. The communication emphasized:
* The introduction of Bambu Connect as the only supported method for interacting with third-party slicers.
* The discontinuation of the network plugin API that OrcaSlicer and other tools relied on for printer control.<ref>https://github.com/SoftFever/OrcaSlicer/issues/8063</ref>
* An invitation for OrcaSlicer developers to adapt their software to integrate with the Bambu Connect URL scheme.


The communication lacked the detailed technical documentation that would be necessary for developers to be able to work with the new requirements.  
Additionally, third-party accessories such as Panda Touch used to allow users to control their printers with a standalone device. Panda Touch was especially popular amongst P series printer owners since P series printers contain a monochromatic screen with a D-pad by default for printer control whereas Panda Touch featured a full-color touch screen According to Big Tree Tech (BTT), the manufacturer of the Panda Touch, they urge users of Panda Touch not to update firmware any further since doing so would foreseeably permanently break compatibility with users' printers and their Panda Touch. <ref name=":0" />


=== How Community Viewed These Actions ===
==Communication with Panda Touch developers==
This approach has been interpreted by many as a calculated move by Bambu Lab to enforce tighter control over its ecosystem. Primary criticisms of Bambu were:
* '''Lack of Transparency''': The limited warning to OrcaSlicer devs suggests that Bambu Lab prioritized internal rollout schedules over community engagement with existing customers.
* '''Disregard for Open-Source Collaboration''': OrcaSlicer is widely used in the community; it is an open-source effort to improve the 3D printing experience for all customers. By abruptly altering the compatibility landscape, Bambu Lab is seen as undermining good-faith initiatives to improve the ecosystem for everyone. The decision to restrict network APIs in favor of proprietary systems such as Bambu Connect represents a broader industry trend of closing off ecosystems that were once open, removing customer choice, privacy, & freedom.
* '''Token Support for Third-Party Tools''': While Bambu Connect provides a workaround for third-party slicer use, it significantly restricts functionality & complicates workflows, leading many to question the sincerity of Bambu's stated support for open tools.<ref>https://wiki.bambulab.com/en/software/bambu-connect</ref>
* '''Power Imbalance''': As the hardware manufacturer, Bambu Lab has the ability to dictate how its products can be used; often to the detriment of third-party devs & users.
== Community-Driven Workarounds and Technical Alternatives ==


Despite the restrictive nature of Bambu Lab's new authorization system, the 3D printing community has already begun exploring potential workarounds to restore functionality and user autonomy. These efforts focus on bypassing or mitigating the limitations imposed by the firmware update.
As of late January 2025, no formal communication between Big Tree Tech (BTT), the manufacturer and developer of Panda Touch, and Bambu Labs had been reported. BTT stated in a Facebook announcement that they had contacted Bambu Lab and would publish updates if Bambu responded.<ref name=":0" />


=== Custom Firmware Development ===
==Communication with OrcaSlicer developers==
Discussions within the community highlight interest in developing custom firmware as an alternative to Bambu's official updates. One prominent project mentioned in forums is the development of custom firmware for the X1-series printers, such as the "X1Plus Custom Firmware."<ref>https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12</ref> This firmware aims to:
* Restore direct network control and third-party slicer compatibility.
* Re-enable previously available features such as motion system adjustments, temperature control, and AMS settings without requiring proprietary software.
* Provide users with greater flexibility in integrating printers with home automation systems and workflows.


However, custom firmware development faces significant challenges, including:
Before the official announcement of the new authorization and authentication, Bambu Lab engaged with the OrcaSlicer development team regarding the changes.
* Limited documentation and proprietary hardware components, which complicate reverse engineering efforts.
* The potential voiding of warranties and risks of bricking devices.
* Legal concerns regarding intellectual property and bypassing manufacturer-imposed restrictions.


== Community Tools and Scripts ==
===Pre-announcement contact===
In addition to firmware alternatives, some users have come up with custom scripts & software tools to interface with Bambu Lab printers indirectly. These tools often rely on:
Reports from OrcaSlicer demonstrate that Bambu Lab provided limited advance notice of the changes that would render their software incompatible with Bambu printers running the new firmware. The communication emphasized:
* Reverse-engineering the URL-based commands required by Bambu Connect to enable partial functionality with third-party slicers like OrcaSlicer.
*The introduction of Bambu Connect as the only supported method for interacting with third-party slicers.
* Creating local server emulations to replicate the network API previously available before the update.
*The discontinuation of the network plugin API that OrcaSlicer and other tools relied on for printer control<ref name="orca-slicer-issue8063" />.
*An invitation for OrcaSlicer developers to adapt their software to integrate with the Bambu Connect URL scheme.


While these tools provide temporary solutions, they don't fully replace the open ecosystem that existed prior to the authorization update.
The communication lacked the detailed technical documentation that would be necessary for developers to be able to work with the new requirements.


=== Advocacy for Open Ecosystem Support ===
===How the community viewed these actions===
Community members have also organized to advocate for open-source support and rollback options. Suggestions include:
Primary criticisms of Bambu were:
* Allowing an opt-out option for existing users who prefer local network control without cloud dependency.
*'''Lack of transparency''': SoftFever reported that the limited warning given to OrcaSlicer developers preceded community engagement with existing customers.<ref name="orca-slicer-issue8063" /> Point to the contrary: the new firmware is in beta and Bambu Connect middleware contains temporary compromises to allow third-party slicers to work as before.
* Providing an official API for third-party slicers under specific licensing agreements that allow secure authorized usage.<ref>https://github.com/SoftFever/OrcaSlicer/issues/8063</ref>
*'''Lack of follow-through:''' As of January 2025, SoftFever, OrcaSlicer's lead developer, did not have API keys for Bambu Connect, a necessary layer of Bambu software that would need to be integrated into OrcaSlicer. Some community members questioned whether Bambu Lab's outreach to OrcaSlicer was a substantive collaboration effort.<ref name=":1">{{Cite web |last=@fever_soft |date=2025-01-18 |title=This is definitely a bummer.

*'''Power imbalance''': As the hardware manufacturer, Bambu Lab has the ability to dictate how its products can be used; often to the detriment of third-party developers and users.


=== Conflict with Open Source and Maker Values ===
==Community-driven workarounds and technical alternatives==
Bambu Lab's printers became popular within the maker community partly due to their integration with open-source tools & community-developed software. The authorization system represents a fundamental shift away from these values, moving from an open ecosystem where users could freely modify & automate their printers to a closed, manufacturer-controlled environment. This change impacts:

=== Impact on Professional Users and Print Farms ===
However, custom firmware development faces several challenges{{CitationNeeded}}, including:
The restrictions imposed by the new authorization system create significant operational challenges for professional users:
*Limited documentation and proprietary hardware components, which complicate reverse-engineering efforts.
*The potential voiding of warranties and risks of bricking devices.
*Legal concerns regarding intellectual property and bypassing manufacturer-imposed restrictions.


* Print farms can no longer use custom automation systems to manage multiple printers
==Backup of current third party access enabled firmware and network plugins==
* Workflows built around third-party software have to be completely redesigned
A GitHub repository, [https://github.com/Tzeny/bambulabs_plugins_firmware Tzeny/bambulabs_plugins_firmware], contains a backup of the latest firmware released by Bambu Labs for their printers and of the network plugin used by slicers such as Orca Slicer to communicate with the printer.<ref name="tzeny-bambulabs-plugins-firmware">{{Cite web |last=Tzeny |title=bambulabs_plugins_firmware |url=https://github.com/Tzeny/bambulabs_plugins_firmware |website=GitHub |access-date=2026-05-10 |url-status=live}}</ref>
* The requirement to manually export & import files through Bambu Connect creates additional labor
* Integration with existing business systems & workflows becomes more difficult or impossible

=== Privacy & Data Collection Concerns ===
==LAN mode and blocked internet access==
In January 2025, user Tzeny15 on Reddit authored a five step guide to blocking internet access for the Bambu P1S as a precaution in case the manufacturer attempts to limit functionality for printers without the newest firmware.<ref> {{Cite web |last=@Tzeny15 |title=LAN mode with live view, remote monitoring+control and blocked internet access - a five step guide |url=https://www.reddit.com/r/BambuLab/comments/1i4vp5i/lan_mode_with_live_view_remote_monitoringcontrol/ |url-status=live |access-date=2025-05-01 |website=[[Reddit]] |archive-url=http://web.archive.org/web/20250310115818/https://old.reddit.com/r/BambuLab/comments/1i4vp5i/lan_mode_with_live_view_remote_monitoringcontrol/ |archive-date=2025-03-10}}</ref>


The shift toward mandatory use of Bambu's software ecosystem raises several privacy and data collection concerns:
[[Bambu Lab LAN mode guide]]


* All printer operations must now pass through Bambu's cloud infrastructure when using cloud mode
==Community tools and scripts==
* User print data, including file names and print settings, becomes visible to Bambu
In addition to firmware alternatives, some users have come up with custom scripts and software tools to interface with Bambu Lab printers indirectly. These tools often rely on:
* Camera feeds and operational data are processed through Bambu's servers
*Reverse-engineering the URL-based commands required by Bambu Connect to enable partial functionality with third-party slicers like OrcaSlicer.
* Users have limited visibility into how their data is collected, stored, and used
*Creating local server emulations to replicate the network API previously available before the update.
* The system creates dependence on Bambu's cloud services for basic printer functionality<ref>https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/9</ref>


While Bambu Lab maintains that cloud processing is necessary for security and functionality, community members argue this represents unnecessary data collection that could be handled locally<ref>https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12</ref>. The company's cloud infrastructure costs are significant, leading some users to speculate that future monetization of the cloud services may be planned<ref>https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/5</ref>.
While these tools provide temporary solutions, they do not fully replace the open access that existed before the firmware update.


This shift from local control to cloud-dependent operation is part of a broader trend in consumer devices, where manufacturers use security concerns to justify increased data collection & reduced customer control over devices they bought & paid for. The change is devastating to privacy-conscious users who specifically chose to operate their printers in LAN-only mode to avoid cloud connectivity.
===Re-engineering printer-control electronics===
ChazLayyd's Bambu Lab Klipper Conversion project is currently in an incomplete stage<ref>{{Cite web |last=@ChazLayyd |title=Running Klipper on a Bambu Lab machine by replacing it's internal electronics with readily available open-source hardware. |url=https://github.com/ChazLayyd/Bambu-Lab-Klipper-Conversion |url-status=live |access-date=2025-05-01 |website=GitHub |archive-url=http://web.archive.org/web/20251116182420/https://github.com/ChazLayyd/Bambu-Lab-Klipper-Conversion |archive-date=2025-11-16}}</ref><ref>{{Cite web |title=ChazLayyd's Discord Community |url=https://discord.com/invite/W6B5mBejuC |url-access=registration |url-status=live |archive-url=https://web.archive.org/web/20260223033213/https://discord.com/invite/W6B5mBejuC |archive-date=2026-02-23 |website=[[Discord]]}}</ref>. While the project was not made in response to Bambu's announcement, there has been a wave of new public interest in this specific project. ChazLayyd's documentation instructs P1S owners to non-destructively remove the old control electronics that run Bambu's proprietary software and instructs P1S owners to install off-the-shelf control components so that the existing motor connectors and other critical electronics can communicate with the newly-installed off-the-shelf control components.


== Customer Reactions ==
===Advocacy for open-ecosystem support===
 
Community members have also organized to advocate for open-source support and rollback options. Suggestions include:
Customer reactions have been overwhelmingly negative<ref>https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/4</ref><ref>https://old.reddit.com/r/BambuLab/comments/1i2psvz/firmware_update_introducing_new_authorization/</ref>. Bambu Lab has historically pushed cloud-based printer interaction while offering limited LAN mode functionality<ref>https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/9</ref>. Many customers argue that the security issues this locked-down firmware claims to address are actually consequences of the company's cloud-based design choices rather than inherent risks of local network control<ref>https://forum.bambulab.com/t/bambu-studio-1-10-2-public-beta/134549/12</ref>, which continues to infuriate users who are now told that security is the justification for a loss of freedom.
*Allowing an opt-out option for existing users who prefer local network control without cloud dependency.
*Providing an official API for third-party slicers under specific licensing agreements that allow secure authorized usage.<ref name="orca-slicer-issue8063" />


The shift raises privacy concerns as user print data, including file names, print settings, and camera feeds, must now pass through Bambu's cloud infrastructure.  
===X1Plus and other alternative firmware===
X1Plus is an open-source custom firmware version for Bambu Labs printers (more details on the GitHub page). It instructs the printer's auto-update mechanism that the device is on a future version (numbered 99 or higher) so the official firmware does not overwrite the modification.


Many community members & customers ask whether the significant costs of maintaining & deploying this cloud infrastructure might lead to future monetization of these now-mandatory services<ref>https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/5</ref>, with subscriptions required for features that once worked with local access.
*Installation tutorials are available for users who have not yet updated. Installing third-party firmware will void the warranty. Users are advised to consult the GitHub documentation before installation.
*[https://github.com/X1Plus/X1Plus X1Plus on GitHub]
*The Bambu Labs website offers consumers the ability to request a rootable firmware to be sent to their printers.

== Comparisons to Similar Practices by Other Companies ==
==Impact on professional users and privacy concerns==


Bambu Lab's new authorization & authentication requirement is in lock step with industry trends where manufacturers seek to exercise greater control over their hardware ecosystems, limiting autonomy & 3rd party integration under the guise of security. Below are comparisons to similar instances in other industries:
===Impact on professional users and print farms===
The restrictions imposed by the new authorization system create operational challenges for professional users who kept their printers signed into the cloud:


=== Printer DRM and Locked Ecosystems ===
*Print farms can no longer use custom automation systems to manage multiple printers
The most direct parallel to Bambu Lab's actions can be found in traditional 2D printer manufacturers like HP and Epson. These companies have faced backlash for implementing digital rights management (DRM) in printer firmware updates. Key similarities include:
*Workflows built around third-party software have to be completely redesigned
* '''Forced Updates''': Firmware updates have rendered third-party ink cartridges incompatible, forcing users to purchase proprietary consumables.
*The requirement to manually export and import files through Bambu Connect creates additional labor
* '''Restricted Features''': Scanner/printer combos that will not scan if the ink is empty."
*Integration with existing business systems and workflows becomes more difficult or impossible
* '''Consumer Backlash''': Users criticized these updates as anti-consumer, with some pursuing class-action lawsuits for deceptive practices.<ref>https://www.classaction.org/hp-printer-lawsuit</ref>
*Print-farm operators report that the new workflow disrupts their fleet-management workflows<ref name="bambulab-forum-135400/9" />
Print-farm operators can avoid these restrictions by operating their printers in LAN-only mode rather than signing them into Bambu Cloud.


Like 2D printers, Bambu Lab's update restricts functionality previously available to users and pushes them toward proprietary software and cloud-based control.
===Privacy and data-collection concerns===


=== Tesla and Automotive Lock-Ins ===
The shift toward mandatory use of Bambu Studio and Bambu Connect raises several privacy and data collection concerns:
In the automotive industry, Tesla has taken part in similar restrictions through software updates. Examples include:
* '''Remote Feature Removal''': Features like Supercharger access & autopilot have been disabled remotely for second-hand car buyers unless they pay additional fees.
* '''Software Locking''': Tesla restricts modifications and third-party repairs through software locks, requiring users to go through authorized repair centers.<ref>https://www.wired.com/story/tesla-remote-disable-used-car-features/</ref>


Bambu Lab's approach mirrors Tesla’s reliance on firmware updates to enforce its ecosystem, limiting third-party integrations & increasing customer's reliance on proprietary services.
*All printer operations must now pass through Bambu's cloud infrastructure when using cloud mode
*User print data, including file names and print settings, becomes visible to Bambu when cloud is used
*Operational data is processed through Bambu's servers while on a different network. The camera feed, on the other hand, is always peer-to-peer.
*Users have limited visibility into how their data is collected, stored, and used in the cloud
*The system creates dependence on Bambu's cloud services availability for basic printer functionality<ref name=":4" />


=== Relevance to Mission & Purpose of Clinton the CAT ===
While Bambu Lab maintains that cloud processing is necessary for security and functionality, community members argue this represents unnecessary data collection that could be handled locally.<ref name="bambulab-forum-134549/12" /> Users who do not require cloud-based features can disable cloud connectivity and operate the printer through LAN mode.
Bambu Lab's new firmware is part of a growing trend where manufacturers employ software updates to extend control over hardware post-purchase. This often results in:
* '''Monetization of Features''': Features that were once included at purchase are locked behind subscription models or additional fees.
* '''Loss of Ownership''': Consumers lose the ability to fully control and modify devices they own.
* '''Dependence on Proprietary Ecosystems''': Users are locked into a single company's ecosystem, limiting innovation and choice.


While these practices are often justified by claims of security and user experience improvement, they frequently diminish consumer rights and foster mistrust. The similarities between Bambu Lab and other manufacturers demonstrate a concerning shift in how companies manage post-purchase control, highlighting the importance of community advocacy for transparency and ownership rights.
Users who do not want their print data routed through Bambu's cloud infrastructure can operate their printers in LAN-only mode.


= Understanding the Impact for Non-3D Printing Experts =
==Customer reactions==


For those unfamiliar with 3D printing, it might seem like the changes introduced by Bambu Lab's firmware update are minor technical quibbles, rather than a cut against ownership. Yet these changes are a large shift in how users are allowed to interact with devices they purchased & thought they owned.

== What is a 3D Printer & How is it Used? ==
As of publication, '''no changes have been announced for owners who never sign their printers into the Bambu cloud service'''. Past firmware updates allowed pairing the slicer via IP address and access key and performing offline firmware updates without ever signing the printer into the cloud, keeping local functionality unchanged.<ref name="firmware-update-introducing-new-authorization-control-system-2" />
A 3D printer is a device that creates physical objects by building them layer by layer out of materials like plastic. People use 3D printers for:
* '''Personal Projects''': Hobbyists print toys, tools, and decorative items.
* '''Small Businesses''': Entrepreneurs use them to create prototypes, replacement parts, and sell custom items.
* '''Education''': Schools & universities use 3D printers for teaching engineering & design.


To create something with a 3D printer, users typically:
==Comparisons to similar practices by other companies==
1. Design or download a digital file of the object (a 3D model).
2. Use software called a "slicer" to convert the 3D model into instructions the printer can understand.
3. Send the instructions to the printer, which creates the object.


Before this update, users could freely choose from many slicer programs and customize their workflows, including integrating printers with smart home systems for convenience.

Bambu Lab’s new firmware requires authorization for nearly all printer functions:
* Mandatory Software: Users are forced to use Bambu's software, which limits options & removes features previously available through third-party slicers.
* Restricted Control: Home automation systems & custom scripts, which allowed users to automate or remotely manage their printers, are now blocked.
* Cloud Dependency: Many printer functions now rely on Bambu’s cloud servers, requiring constant internet access and raising concerns about privacy and future subscription fees.

Latest revision as of 12:24, 14 May 2026

On January 16, 2025, the 3D-printer manufacturer Bambu Lab announced that future firmwares for its 3D printers would introduce an authorization and authentication mechanism for printer connection and control, in the name of security.[1] The change restricted the use of third-party accessories and slicers such as Panda Touch and OrcaSlicer, and it gated print initiation, motion control, fan and hotend control, AMS configuration, calibrations, remote video, and firmware upgrade behind a Bambu-issued authentication path.[1] Bambu Lab also publishes its own slicer, Bambu Studio, under the AGPL-3.0,[2] while its Terms of Use § 3.4 forbid users to modify, copy, reverse engineer, or create derivatives of "the Product."[3] In April 2026, this authorization system became the basis for a cease-and-desist demand against a Polish community fork maintainer who had restored direct printer control on top of the AGPL source.

Controversy regarding firmware updates

[edit | edit source]
bambu terms stating print jobs may not function properly if update is not performed to new firmware which is highly limiting.
Bambu terms regarding printer functionality and potential for disrupted print jobs if users do not update to a new firmware that radically restricts the autonomy of the owner of the printer

Potential for remote disabling of printers

[edit | edit source]

A concern raised by the community revolves around the wording in Bambu Lab's Terms of Service (ToS) and firmware update announcements. Critics and users argue[citation needed] that the phrasing leaves open the possibility for the manufacturer to remotely disable printers that are not updated to the latest firmware. Specifically, Bambu Lab's ToS warns that printers may block new print jobs if updates are not applied,[3] which some users interpret as a potential pathway for forced obsolescence.[1] While defenders of Bambu Lab point out that offline modes such as SD-card printing and LAN-only setups would remain functional, others point out that the ToS do not explicitly limit this restriction to cloud-based printing. This ambiguity has led to speculation that Bambu Lab could enforce broader limitations, effectively rendering printers inoperable for users who choose not to update.[4]

Editing of initial announcement

[edit | edit source]

Bambu users were concerned they would not be able to use their printer if they did not install this update, due to the wording of the blog and the ToS.[5] This caused confusion since users report that Bambu's blog post dated January 16, 2025[1] includes the FAQ entry:

What happens if I never upgrade to this firmware? You may continue using an older firmware version that does not include the new security updates; however, this means the printers may miss out on important security fixes or bug patches included in newer versions. We highly encourage updating to the latest firmware version for the best experience and enhanced security.

However, this was not present on the day of the announcement. A snapshot of their webpage from archive.is demonstrates this section did not exist on the day of the announcement, when community members voiced their concerns.[1][6] Bambu's response to community feedback[7] references "social media posts spreading baseless allegations and untrue claims about Bambu Lab", including "Firmware updates will block your printer's ability to print.", without mentioning the context for those allegations. The context for those allegations was the lack of inclusion of the "What happens if I never upgrade to this firmware?" in Bambu's initial announcement alongside their stated terms of service.

After the edit, the announcement header reads Updated: January 17, 2025 and notes that additional details and FAQs (including the "What happens if I never upgrade to this firmware?" entry) were added.

The earliest archive.is snapshot of the announcement, dated January 16, 2025 17:31 UTC,[8] contains two passages about staying on the old firmware. Under "Important Information for End Users":

2. Old Firmware Option: Users who decide to use an older firmware version can still use the previous or new versions of Bambu Studio and Bambu Handy without restrictions.

Under "Information for OrcaSlicer users":

1. You can continue using your X Series 3D printer with the older firmware version (which does not include Authorization Features). 2. If you choose to upgrade to the firmware version with Authorization Features, you must download and install Bambu Connect (a printer control software).

The FAQ section was added after the initial blog post publication and is noted as an update in the announcement header.

Debate over "bricking" terminology

[edit | edit source]

The debate has also extended to the definition of "bricking". Some community members assert that if a printer is unable to accept new print jobs without an update, it effectively becomes non-functional and qualifies as being "bricked." Others counter that as long as certain offline functionalities remain (such as SD-card printing) the term does not accurately apply.[4]

Privacy policy issues

[edit | edit source]

Bambu Lab's privacy policy describes that when a user submits a print job through Bambu cloud, Bambu may forward configuration information, printing settings, model picture, plate thumbnails and G-code files (referred to in the policy as "Printing Files"), and when the print history reprinting feature is enabled, may store started times, finished times, and filament consumption.[9] The privacy policy webpage is not present in the Wayback Machine.[9]

Community strategies to deal with risks

[edit | edit source]

Users have discussed strategies to avoid possible disruptions, including:

  • Operating printers exclusively in offline modes.
  • Using LAN connections or VPN setups: this requires an access key from the printer (previously, you could use your cloud credentials over LAN).
  • Exploring alternative firmware or third-party scripts to restore full functionality.[4]

Bambu Lab's justification and rebuttal

[edit | edit source]

Bambu Lab has stated that the authorization system is in place in order to protect against "remote hacks," "printer exposure," and "abnormal traffic or attacks". The cited security incidents have specific context:

  • The "remote hacks" cited as an example in the article followed a reported security vulnerability in a 3D printer product; according to Bitdefender's reporting, the researcher infected machines to display a harmless message in order to publicize the unpatched flaw.[10]
  • In the article cited about printer exposure, the hack was carried out largely because of user misconfiguration.[11]
  • The "abnormal traffic" can be mitigated by steps Bambu has already put in place, as detailed in their own article on the matter.[12]
  • "Other malicious devices in the LAN" can be partially mitigated by steps Bambu has already put in place, as detailed in their own article on the matter.[13]

Issues with LAN mode requiring authorization

[edit | edit source]

📅This section may be outdated. Some information may no longer reflect the current situation.

Bambu Connect App - Lan Device Discovery without Bambu Login

Bambu Lab printers have the ability to be controlled over both cloud and LAN. This allowed users to integrate their printers into private networks and maintain full control without having to rely on the manufacturer's server while also allowing cloud access. The new authorization system mandates that even LAN-based operations must go through an authentication process using Bambu Connect to retain full control.[14] Full local access is still possible and unchanged for those not using the cloud.

This change has drawn criticism for many reasons:

  • Privacy concerns: Requiring authentication for LAN mode raises concerns about data being unnecessarily exposed to Bambu Lab's servers, even for local-only operations, though previously, the printer was also connected and could be controlled by the cloud even when sending prints locally.
    • Confidentiality required by US Law: this is in conflict with users that have to comply with internal U.S. government classified information handling regulations.[citation needed]
  • Loss of offline independence while also using cloud: Before, users could have hybrid offline setups. The requirement for authentication removes this option unless users revert to older firmware versions; Bambu Lab initially indicated rollback would not be permitted, though The Verge later reported that users could still downgrade and use LAN access keys while signed into the cloud.
  • Increased complexity: The added authentication layer complicates workflows for users who built custom setups or relied on third-party integrations for LAN control while retaining cloud functionality.[15]
  • LAN-Only mode in Orca Slicer is implemented by passing API Calls to the installed proprietary Bambu Network Plug-In (unlike BTT and other solutions that did indeed communicate with printer directly via MQTT protocol).
  • Plug-In provides controls for Printers "Critical Operations" (as classified by the Firmware Announcement article) and displays these controls within the window of Orca Slicer.
  • Using intermediary Plug-In does not manifest as "direct access through network plugin". It is still a Proxy communication, even if user experience is presented as direct communication (same slicer window).
  • Bambu Connect moves the Network Plug-In functionality outside of the window of Orca Slicer thus appearing as separate window and presents the appearance of "indirect" communication channel to the printer.
  • While the user experience is different, the flow remains unchanged Orca Slicer slices model -> Orca Slicer Calls API of Bambu Proprietary Software -> Bambu Proprietary Software controls the printer.

Additionally, Bambu Connect software (downloaded and installed in January 2025, before the backlash response) supports adding LAN-Only printers without requiring Bambu Account authentication, the same behavior as the Network Plugin used in Orca Slicer.[citation needed]

X1E firmware 01.01.02.00 LAN-mode connection failure

[edit | edit source]

Newly received X1E printers with firmware 01.01.02.00 will not connect to the Bambu Studio using the Lan only method password. Bambu Studio identifies the un-logged printer but will not allow a connection to the printer. Only after connection / account pairing is done over the Bambu Handy app by giving internet access to the PC and Printer then using the cloud service connection will Lan only communication and login work.[16]

Implementation timeline and requirements

[edit | edit source]

📅This section may be outdated. Some information may no longer reflect the current situation.

The authorization system will be rolled out in phases, starting with the X1 series printers. A beta firmware (version 01.08.03.00) was released on January 17, 2025, with the full release scheduled for late January 2025.[1] The P and A series printers will get similar updates at an unspecified future date.

To use printers with the new authorization system, users must update multiple pieces of software:[1]

  • Bambu Studio must be updated to version 01.10.02.64 or higher
  • Bambu Handy mobile app must be updated to version 2.17.0 or higher
  • The new Bambu Connect application must be installed for using third-party slicers

These software updates are mandatory for users who update their firmware. Failing to update all components simultaneously will result in certain printer controls becoming unusable. Users who choose to maintain third-party software compatibility can continue using older firmware versions, or downgrade the firmware for new printers that ship with the authorization system pre-installed.[1]

Bambu Lab states these coordinated updates are necessary because the new authorization system changes how the printer validates and accepts commands. The older versions of Bambu Studio and Bambu Handy lack the authentication mechanisms required to interact with printers running the new firmware. The Bambu Connect application was created specifically to provide a controlled interface for third-party software, replacing the previous direct access through network plugins.[1]

Impact on third-party integration and user choice

[edit | edit source]

Changes to third-party access

[edit | edit source]

The new authorization system replaces direct network API access with a more limited URL-based interface through Bambu Connect. Third-party software can only interact with the printer by sending specific URL commands to Bambu Connect.[14] The interface requires three parameters:

  • path: The absolute file system path to the 3MF file (e.g., /tmp/cube.gcode.3mf)
  • name: The name of the file (e.g., Cube)
  • version: A fixed value of 1.0.0 for compatibility

A complete command must be formatted as: 

bambu-connect://import-file?path=%2Ftmp%2Fcube.gcode.3mf&name=Cube&version=1.0.0

This interface only allows basic file transfer and print initiation. All other printer-control functions previously available to third-party software are now exclusive to Bambu's own applications. The path and name parameters must be URL-encoded using encodeURIComponent or equivalent functions[14].

Reduced home-automation capabilities

[edit | edit source]

While basic status monitoring remains available (e.g., print-progress updates in Home Assistant), the new firmware removes the ability for home-automation systems to control printer functions. Users can no longer:

  • Start or stop prints remotely using Home Assistant, BTT Panda Touch,[17] or other third-party accessories or software interfaces
  • Control printer temperatures or cooling
  • Automate printer behaviors based on sensor data or events
  • Access camera feeds through third-party applications[18]

Impact on functionality

[edit | edit source]

📅This section may be outdated. Some information may no longer reflect the current situation.

While some functionality remains unauthenticated like in previous firmware versions (sending status information from the printer over the network, starting a print job using SD cards), the most important features now require authentication through a closed-source client called Bambu Connect[14]. These restricted features include:

  • Initializing prints via LAN or cloud mode
  • Remote video access to monitor prints
  • Controlling motion system, temperature, fans
  • AMS settings and calibrations
  • Home automation integration beyond basic status monitoring

Previously, third-party software such as OrcaSlicer[19] could interact with Bambu Lab printers via the open-source Bambu Studio and proprietary network plug-ins. While Bambu Connect provides a limited URL-based API to initiate prints, most functionality previously openly available is now restricted to Bambu's ecosystem[18].

Additionally, third-party accessories such as Panda Touch used to allow users to control their printers with a standalone device. Panda Touch was especially popular amongst P series printer owners since P series printers contain a monochromatic screen with a D-pad by default for printer control whereas Panda Touch featured a full-color touch screen According to Big Tree Tech (BTT), the manufacturer of the Panda Touch, they urge users of Panda Touch not to update firmware any further since doing so would foreseeably permanently break compatibility with users' printers and their Panda Touch. [17]

Communication with Panda Touch developers

[edit | edit source]

As of late January 2025, no formal communication between Big Tree Tech (BTT), the manufacturer and developer of Panda Touch, and Bambu Labs had been reported. BTT stated in a Facebook announcement that they had contacted Bambu Lab and would publish updates if Bambu responded.[17]

Communication with OrcaSlicer developers

[edit | edit source]

Before the official announcement of the new authorization and authentication, Bambu Lab engaged with the OrcaSlicer development team regarding the changes.

Pre-announcement contact

[edit | edit source]

Reports from OrcaSlicer demonstrate that Bambu Lab provided limited advance notice of the changes that would render their software incompatible with Bambu printers running the new firmware. The communication emphasized:

  • The introduction of Bambu Connect as the only supported method for interacting with third-party slicers.
  • The discontinuation of the network plugin API that OrcaSlicer and other tools relied on for printer control[19].
  • An invitation for OrcaSlicer developers to adapt their software to integrate with the Bambu Connect URL scheme.

The communication lacked the detailed technical documentation that would be necessary for developers to be able to work with the new requirements.

How the community viewed these actions

[edit | edit source]

Primary criticisms of Bambu were:

  • Lack of transparency: SoftFever reported that the limited warning given to OrcaSlicer developers preceded community engagement with existing customers.[19] Point to the contrary: the new firmware is in beta and Bambu Connect middleware contains temporary compromises to allow third-party slicers to work as before.
  • Lack of follow-through: As of January 2025, SoftFever, OrcaSlicer's lead developer, did not have API keys for Bambu Connect, a necessary layer of Bambu software that would need to be integrated into OrcaSlicer. Some community members questioned whether Bambu Lab's outreach to OrcaSlicer was a substantive collaboration effort.[20]
  • Disregard for open-source collaboration: OrcaSlicer is open-source software developed under the AGPL-3.0 license.[21] The decision to restrict network APIs in favor of proprietary systems such as Bambu Connect removes customer choice in how the printer is operated.
  • Token support for third-party tools: While Bambu Connect provides a workaround for third-party slicer use, it restricts functionality and complicates workflows, leading many to question the sincerity of Bambu's stated support for open-source tools[14].
  • Power imbalance: As the hardware manufacturer, Bambu Lab has the ability to dictate how its products can be used; often to the detriment of third-party developers and users.

Community-driven workarounds and technical alternatives

[edit | edit source]

📅This section may be outdated. Some information may no longer reflect the current situation.

Community members have published workarounds for the firmware restrictions.

Custom firmware development

[edit | edit source]

Discussions took place within the community concerning the development of custom firmware as an alternative to Bambu's official updates. One prominent project mentioned in forums is the development of custom firmware for the X1-series printers, such as the "X1Plus Custom Firmware"[22]. This firmware aims to:

  • Restore direct network control and third-party slicer compatibility.
  • Re-enable previously available features such as motion-system adjustments, temperature control, and AMS settings without requiring proprietary software.
  • Provide users with greater flexibility in integrating printers with home-automation systems and workflows.

However, custom firmware development faces several challenges[citation needed], including:

  • Limited documentation and proprietary hardware components, which complicate reverse-engineering efforts.
  • The potential voiding of warranties and risks of bricking devices.
  • Legal concerns regarding intellectual property and bypassing manufacturer-imposed restrictions.

Backup of current third party access enabled firmware and network plugins

[edit | edit source]

A GitHub repository, Tzeny/bambulabs_plugins_firmware, contains a backup of the latest firmware released by Bambu Labs for their printers and of the network plugin used by slicers such as Orca Slicer to communicate with the printer.[23]

LAN mode and blocked internet access

[edit | edit source]

In January 2025, user Tzeny15 on Reddit authored a five step guide to blocking internet access for the Bambu P1S as a precaution in case the manufacturer attempts to limit functionality for printers without the newest firmware.[24]

Bambu Lab LAN mode guide

Community tools and scripts

[edit | edit source]

In addition to firmware alternatives, some users have come up with custom scripts and software tools to interface with Bambu Lab printers indirectly. These tools often rely on:

  • Reverse-engineering the URL-based commands required by Bambu Connect to enable partial functionality with third-party slicers like OrcaSlicer.
  • Creating local server emulations to replicate the network API previously available before the update.

While these tools provide temporary solutions, they do not fully replace the open access that existed before the firmware update.

Re-engineering printer-control electronics

[edit | edit source]

ChazLayyd's Bambu Lab Klipper Conversion project is currently in an incomplete stage[25][26]. While the project was not made in response to Bambu's announcement, there has been a wave of new public interest in this specific project. ChazLayyd's documentation instructs P1S owners to non-destructively remove the old control electronics that run Bambu's proprietary software and instructs P1S owners to install off-the-shelf control components so that the existing motor connectors and other critical electronics can communicate with the newly-installed off-the-shelf control components.

Advocacy for open-ecosystem support

[edit | edit source]

Community members have also organized to advocate for open-source support and rollback options. Suggestions include:

  • Allowing an opt-out option for existing users who prefer local network control without cloud dependency.
  • Providing an official API for third-party slicers under specific licensing agreements that allow secure authorized usage.[19]

X1Plus and other alternative firmware

[edit | edit source]

X1Plus is an open-source custom firmware version for Bambu Labs printers (more details on the GitHub page). It instructs the printer's auto-update mechanism that the device is on a future version (numbered 99 or higher) so the official firmware does not overwrite the modification.

  • Installation tutorials are available for users who have not yet updated. Installing third-party firmware will void the warranty. Users are advised to consult the GitHub documentation before installation.
  • X1Plus on GitHub
  • The Bambu Labs website offers consumers the ability to request a rootable firmware to be sent to their printers. As of January 26, 2025, the feature (in the EU at least) is broken such that you cannot finalize the process of requesting such a firmware.[27]
    • The result of accepting the terms of the page titled "Third Party Firmware Plan Guideline" and clicking "Next" takes you to a page titled "Important Notice and Risk Warning" which, when accepting the terms leaves you with an "I got it" button that takes you back to the previous page.

Impact on professional users and privacy concerns

[edit | edit source]

Impact on professional users and print farms

[edit | edit source]

The restrictions imposed by the new authorization system create operational challenges for professional users who kept their printers signed into the cloud:

  • Print farms can no longer use custom automation systems to manage multiple printers
  • Workflows built around third-party software have to be completely redesigned
  • The requirement to manually export and import files through Bambu Connect creates additional labor
  • Integration with existing business systems and workflows becomes more difficult or impossible
  • Print-farm operators report that the new workflow disrupts their fleet-management workflows[18]

Print-farm operators can avoid these restrictions by operating their printers in LAN-only mode rather than signing them into Bambu Cloud.

Privacy and data-collection concerns

[edit | edit source]

The shift toward mandatory use of Bambu Studio and Bambu Connect raises several privacy and data collection concerns:

  • All printer operations must now pass through Bambu's cloud infrastructure when using cloud mode
  • User print data, including file names and print settings, becomes visible to Bambu when cloud is used
  • Operational data is processed through Bambu's servers while on a different network. The camera feed, on the other hand, is always peer-to-peer.
  • Users have limited visibility into how their data is collected, stored, and used in the cloud
  • The system creates dependence on Bambu's cloud services availability for basic printer functionality[15]

While Bambu Lab maintains that cloud processing is necessary for security and functionality, community members argue this represents unnecessary data collection that could be handled locally.[22] Users who do not require cloud-based features can disable cloud connectivity and operate the printer through LAN mode.

Users who do not want their print data routed through Bambu's cloud infrastructure can operate their printers in LAN-only mode.

Customer reactions

[edit | edit source]

Customer reactions on community forums and Reddit were negative.[28][29] Bambu Lab has historically pushed cloud-based printer interaction while offering limited LAN mode functionality[15]. Many customers argue that the security issues this locked-down firmware claims to address are actually consequences of the company's cloud-based design choices rather than inherent risks of local network control.[22] After the announcement, Bambu Lab's Trustpilot page recorded a wave of one-star reviews citing the firmware restrictions as the reason for the rating.[30]

As of publication, no changes have been announced for owners who never sign their printers into the Bambu cloud service. Past firmware updates allowed pairing the slicer via IP address and access key and performing offline firmware updates without ever signing the printer into the cloud, keeping local functionality unchanged.[1]

Comparisons to similar practices by other companies

[edit | edit source]

Bambu Lab's new authorization and authentication requirements have been compared to a number of practices by traditional printer manufacturers, such as HP and Epson, who have faced backlash and litigation over digital rights management (DRM) practices in 2D printers.[citation needed]

A parallel from the 3D-printing industry is the 3D-printer manufacturer MakerBot, whose 2012 shift from open-source, DIY-focused machines to closed-source, proprietary machines drove customers to less-expensive open-source competitors, as documented by Hackaday's 2016 obituary of the company.[31] MakerBot was also accused of asserting ownership over publicly available, open-source designs uploaded to its 3D print repository, Thingiverse.[32]

TOS restricting development of third party devices and accessories

[edit | edit source]

Archived discussion threads from January 2024 confirm that a clause restricting the development of third party devices and accessories - § 3.1 - has been part of the Bambu Lab Terms of Use at least since then.[33] Community reaction was split: some readers argued the clause is intended to restrict third-party development, while others characterized it as standard boilerplate in vendor terms.[34]

Bambu Lab's Terms of Use § 3.1 states:

3.1 You may not use Bambu Lab technology or Bambu Lab intellectual property to develop software or design, develop, manufacture, sell, or licence third-party devices/accessories associated with Bambu Lab Product without Bambu Lab's prior consent.

Improvements Introduce authorization and authentication protection mechanism: Bambu Studio now supports signing and encrypting control commands sent to printers when the printer supports authorization and authentication protection. The printer will determine whether the commands can be executed. Hmmm. This reads suspiciously vague. It could mean that Bambu printers get an onboard permission handling, so that you can "lock down" your printer and set what commands can be run. But it could also mean that Bambu printers in (or of?) the future will only run Gcode encrypted and signed by Bambu Studio…
