Nvidia GeForce RTX 5090 power wire reportedly caught fire despite using the original cable
I opened up my original Bambu Lab A1, a machine with nearly a thousand print hours, and found no signs of damage or overheating.
The red arrow below points to the NTC on the A1’s power board if you want to inspect your own printer. The Bambu Lab Wiki includes directions for replacing the AC board, which is a user-serviceable part .
Posner said that he has been in contact with Bambu Lab, and despite his conversation with the team at Formnext, he still believes the printer is a fire hazard and should be recalled. He suggests that anyone with an A1 should place a fireproof paving stone underneath the machine.
Bambu Lab told us that all 3D printers, like any valuable household electronic device, should be used with a surge protector to prevent damage from power spikes .
This would not be the first time the A1 came under scrutiny for safety-related issues. The 3D printer was subject to an official recall we reported on in January 2024 . That recall was related to a cable design that could stress and arc when the machine was tilted backward.

Konomi I'd say the issue is probably not that big of a deal. Sure, if things are melting that shouldn't, that's a design problem but also on the other side of the coin, people need to remember these aren't toys. Naturally you should have a well-ventilated workspace, use appropriate surge protection equipment and generally use common sense around such equipment. Reply
edzieba Meanwhile, Redditors on another thread suggest that Posner simply has an ax to grind with Bambu. A quick check of the 3D Musketeers channel reveals dozens of videos critical of the company. That's somewhat of an understatement. When the X1Plus team first discovered how to root the X1C's firmware, they shared this with a bunch of youtubers before making the custom firmware publicly available. Posnmer put out a video making several claims, such as: – Bambu using open source software in their firmware – The printer connecting to Bambu servers in LAN mode – The printer sending detailed logs to Bambu in LAN mode without user action With no actual evidence ever provided. Bambu subsequently fixed the vulnerability the X1Plus team found, whilst also adding the ability to downgrade to the vulnerable firmware for those who want to use the X1Plus firmware. The X1Plus firmware was subsequently released to the public, anyone can install it and have root access to their printers, examine all the software installed on them, examine what is logged, what the printer is connecting to (which could also be done before that with Wireshark and similar) and it was found… none of Posner's claims were actually true . He'd just made them up. Reply
T3Kgamer It's like the Ender 3 all over again. Reply
