A1 melting safety risk

TLDR: A component called a NTC thermistor on the AC board can overheat and catch fire. In some cases it melts through the bottom of the A1. 3D Musketeers have collected 70 reports of this problem. BambuLab remains silent on the issue. If you run a A1 please place it on a non-flammable surface.

This has to be the worst A1 fire I've seen so far

I saw this not too long ago on Instagram. I can basically guarantee that there will be another recall.

This has to be the worst A1 fire I've seen so far

I was aware that the NTC is a problem and I just waited for it to happen to my A1. And for sure it did happen. If I had seen the aftermath of OP‘s incident I wouldn’t have waited for it to happen but contacted the support right away. Here’s my post if you haven’t seen it already. I‘ll be adding a ph

My new bambu lab setup

The A1 is not designed for enclosing, you risk overheating the electronics. The A1 already has an active ongoing fire / meltdown risk, enclosing the A1 does not do it any favors. This is the latest example not even 12h ago https://www.reddit.com/r/BambuLab/comments/1q2no79/bambu_a1_hole_burned_through_b

Bambu Lab owners be all like:

/uj Can I just remind the Bambu owners furiously downvoting this that we're in r/3DPrintingCirclejerk and not r/VerySerious3DPrinting. It's intended purely as a joke about the A1s and their propensity to melt and occasionally catch fire, not a actual statement of my opinion. Example here: https://ww

There isn't a chance of a fire though unless the end user has done something like wrap their machine in a flammable cloth deliberately So then explain this https://www.reddit.com/r/BambuLab/comments/1tgt4mz/this_has_to_be_the_worst_a1_fire_ive_seen_so_far/
