}}

On January 16, 2025, the 3D-printer manufacturer '''[[Bambu Lab]]''' announced that future firmwares for their 3D printers would introduce an authorization and authentication protection mechanism for their connection and control, [[Deceptive language frequently used against consumers|in the name of security]]. This mechanism restricts the use of third-party accessories and slicers, such as Panda Touch and OrcaSlicer.

==Controversy regarding firmware updates==

====Editing of initial announcement====

<blockquote><strong>What happens if I never upgrade to this firmware?</strong>

*'''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 those that have to comply with 18 CFR § 3a.61, 32 CFR § 117.15, 32 CFR § 2001.47, and other restrictions.

*'''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=Jan 2023 |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.

*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.

*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.

===Precedents and comparisons===

===X1E firmware 01.01.02.00 LAN only connection "BUG"===

==Communication with OrcaSlicer developers==

===Pre-announcement contact===

===How the community viewed these actions===

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 follow-through:''' As of writing, SoftFever, OrcaSlicer's lead developer, still does not have API keys for Bambu Connect, a necessary layer of Bambu software that would need to be integrated into OrcaSlicer. Bambu's original announcement prominently mentioned OrcaSlicer and gave the impression that Bambu is actively providing the necessary assets so that SoftFever would be able to implement the new software architecture so that OrcaSlicer users are able to still use OrcaSlicer to send gcode to their printers without needing Bambu Connect to be installed as a separate program. The lack of active cooperation does not reflect favorably upon Bambu as it seems like their announcement used OrcaSlicer's name to try to make it seem like Bambu is trying its best to make sure that developers have what they need, but in reality, their inaction seems to show that Bambu is not making a sincere attempt to ensure that OrcaSlicer remains supported<ref name=":1" />.

*'''Token support for third-party tools''': While Bambu Connect provides a workaround for third-party slicer use, it significantly restricts functionality and complicates workflows, leading many to question the sincerity of Bambu's stated support for open-source tools<ref name="bambu-connect" />.

*'''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.

*Provide users with greater flexibility in integrating printers with home-automation systems and workflows.

*Limited documentation and proprietary hardware components, which complicate reverse-engineering efforts.

*The potential voiding of warranties and risks of bricking devices.

*Creating local server emulations to replicate the network API previously available before the update.

===Re-engineering printer-control electronics===

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.<ref name="orca-slicer-issue8063" />

Currently X1Plus a OPEN SOURCE custom firmware version for Bambu Labs printers(more details on the GitHub page)

*https://github.com/X1Plus/X1Plus

*The Bambu Labs website offers consumers the ability to request a rootable firmware to be sent to their printers. At the time of writing (Jan 26, 2025), the feature (in the EU at least) is broken such that you cannot finalize the process of requesting such a firmware. Ref: https://bambulab.com/en-eu/third-party-firmware/plan

**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 print farms===

*Print farms can no longer use custom automation systems to manage multiple printers

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" />. The company's cloud infrastructure costs are significant, leading some users to speculate that future monetization of the cloud services may be planned<ref name="bambulab-forum-3643/5">{{Cite web |last=@NeverDie |date=Jan 2025 |title=Full Non-Cloud Based Network Option Needed |url=https://forum.bambulab.com/t/full-non-cloud-based-network-option-needed/3643/5 |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=I’m not disagreeing, but as a short-term workaround, are you able to write the print files to an SD card and then print from that? I’m too new to have tried it myself, but I thought that was at least an option.}}</ref>. Therefore, people should assess if their use case mandates the use of the cloud service and disable it when it doesn't.

==Customer reactions==

Many community members and customers ask whether the significant costs of maintaining and deploying this cloud infrastructure might lead to future monetization of these now-mandatory services,<ref name="bambulab-forum-3643/5" /> with subscriptions required for features that once worked with local access.

==Comparisons to similar practices by other companies==

*'''Forced updates''': Firmware updates have rendered third-party ink cartridges incompatible, forcing users to purchase proprietary consumables.

*'''Restricted features''': Scanner/printer combos that will not scan if the ink is empty.

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