Why does the 3D printer heat up? Wouldn’t the print melt? Shouldn’t it instead cool down so the print would freeze?
In: 0
There are many different kinds of 3d printers, and they all use different methods. I’m not familiar with them all but the kind I have SLA:
Works with a liquid resin that is kept at room temperature and exposed to UV light from a small screen that sits under the print surface.
It will heat some, but even after 8-10 hour prints I doubt it’s much more than a few degrees of temp.
I can’t speak of other kinds.
