A new video of a Bambu Lab A1 3D printer melting down to its metal chassis has sparked debate about the device's safety. Community members are discussing whether this incident relates to a previously reported NTC thermistor fire hazard or if external factors caused the damage.
Community members debate whether the incident relates to a previously reported NTC thermistor fire hazard or external factors.
Users have shared observations suggesting the melted object between two printers may indicate proximity damage from another burning source on the desk. One user noted their machine experienced similar issues after three months of use, with others reporting comparable incidents. Another commenter suggested the burned mess points to a significant event affecting multiple devices nearby.
The exact cause of the fire remains unknown due to a lack of video evidence showing the actual incident. Some users argue the printer is likely from post-fix production runs and therefore not affected by the known thermistor issue. Others suspect external factors played a role in the damage observed on the right side of the unit.
This incident has reignited calls for a recall among some Bambu Lab A1 owners, while others continue to debate the root cause. The manufacturer has not issued an official statement regarding this specific case or broader safety concerns surrounding the model.
