Concerns are being raised within the 3D printing community regarding the Bambu Lab A1 after a recent video by YouTuber Grant Posner (3D Musketeers) revealed a possible safety issue. Posner has seen an alarming number of A1 printers with charred or melted cases, which suggests that the A1’s AC power distribution board may be operating above normal temperatures, posing a risk of fire. The AC power board uses an NTC thermistor to limit inrush current and is active only while the printer is rapidly warming up. Posner claims this thermistor is being pushed too close to its rated limits.
