3D printing innovator Bambu Lab has taken decisive action by issuing a recall for its latest offering, the A1 3D printer. In a recent blog post, the company revealed that certain units of the A1 model may harbor damaged cables connecting the heat bed to the printer’s main body, potentially posing a fire hazard. One reported incident on the Bambu Forum detailed machine burns and a resultant power outage in a user’s home, underscoring the severity of the issue.
The blog post outlined several scenarios in which cable damage could occur, attributing the problem to inadequate strain relief (SR) design. Factors such as rough handling during transportation, improper installation placing undue stress on the cable, or accidental external force post-installation were identified as potential culprits.
To address the issue, Bambu Lab has proposed two solutions. Users detecting cable damage, indicated by a squeezed-in shape near the printer base, are urged to promptly fill out a form for return shipment of the faulty unit and receipt of a replacement. Additionally, individuals concerned about potential damage, even in the absence of visible signs, are advised to cease printer operation immediately and complete the form. Recognizing the urgency of the situation, Bambu Lab emphasizes the importance of swift action to mitigate fire risks.
For users seeking proactive measures, Bambu Lab suggests 3D printing a cable guard to safeguard against cable kinking. While the inclusion of this guard in future A1 shipments remains unconfirmed, the company has committed to repackaging existing units to prevent cable damage during transit.
