Comment on Automatic Fire Extinguisher for 3D Printer Cabinet
SzethFriendOfNimi@lemmy.world 5 months agoIt’s not that they melt as much as they just keep dumping heat into the heater cartridge and wires.
And if failed in an on state thermal runaway isn’t going to stop it.
It’s relatively rare though. I’m not too worried about it but it’s one of the reasons I watch my printer and of course there’s thermal fuses for such occasions if you really needed it.

Ideally the heater shouldn’t be powerful enough to set itself on fire even at 100% power I guess.
For bed heaters there are thermal fuses.

The heater no, but a blob of filament with the heat pumping into it is worrying.
