Editing QIDI 3D printer house fire (section)

==The incident: House fire and censorship allegations==

The controversy began on March 31, 2025, when Reddit user u/ProgressLocal1511 alleged that their Qidi Tech Plus 4 printer had catastrophically failed and started a fire that resulted in the complete destruction of their home. According to the user's account, the printer was operating with PETG filament. Approximately 15 to 30 minutes after a routine check, smoke alarms were triggered. The user discovered dense smoke and flames emanating from the rear of the machine, and the fire escalated too rapidly to be controlled with a home fire extinguisher.<ref name="RedditPost" />

The incident's scope expanded significantly when the user reported that their attempts to warn other owners on the official r/QidiTech3d subreddit were censored. They claimed their posts were removed and their account was permanently banned from the forum.<ref name="RedditPost" /> This action was perceived by the broader community as an attempt to suppress critical safety information, triggering the "Streisand effect," where the effort to censor the report amplified its reach across social media and 3D printing news outlets.<ref name="Fabbaloo">{{Cite web |last=Stevenson |first=Kerry |date=4 Apr 2025 |title=Reports Emerge of Fires Caused by Qidi Plus 4 3D Printer |url=https://www.fabbaloo.com/news/reports-emerge-of-fires-caused-by-qidi-plus-4-3d-printer |access-date=5 Aug 2025 |website=Fabbaloo}}</ref>
