New video of melted Bambu Lab A1 sparks debate about whether the 3D printer is still a fire hazard — critics push for recall while redditors suspect external factors

A video of a heavily melted Bambu Lab A1 has reignited fire-safety concerns around the popular 3D printer.

The debate centers on whether the damage came from the A1’s known power-board NTC thermistor issue or from external conditions near the machine.

Some users and commentators are calling for a recall, while others say the video does not prove the printer itself caused the melt.

The incident could further pressure Bambu Lab as it faces scrutiny over whether the A1’s safety problem has been fully resolved.
