Bambu recently posted another statement. We have read something similar before and much of it is repetitive. Here is the latest version, which goes into much greater detail:
We have been closely following the reports, and we truly appreciate everyone for bringing these concerns to our attention.
Our investigation shows that reported failures are linked to abnormal surges or overvoltage events (such as lightning), which can damage the NTC thermistor. While a damaged NTC can cause temperatures to reach 160°C—leading to the softening, deforming, or melting of nearby plastic components—it does not lead to ignition or sustained combustion. Due to our use of flame-retardant materials, the confirmed incidence rate remains very rare, well below 0.1%, and importantly, there have been no reported cases of fire.
After reviewing field data, we determined the benefits of NTC-based inrush protection were outweighed by potential downsides under rare surge conditions. As a result, we implemented a design change in Q3 2025 to remove the NTC from the circuit.
If your printers have experienced damage or malfunction related to NTC failure, we have been and continue to provide repair or replacement support through our customer support channels. Please feel free to contact our support team, and we will ensure you receive the best possible solution.
Thank you so much for your understanding and continuous support!
