I believe this question is asked on every private Beta... what should be the name of our chatroom?
Colloquially, "hotbed" generally refers to a center of activity. Here, it will have a double meaning (referencing the hot bed of a 3D printer.
Slicing a 3d model is a necessary step for almost all 3D printing techniques, so that it can be printed layer by layer that eventually make up the 3D object.
In chat, people write text line by line which will eventually make up an entire conversation.
Since everything happens in the box.
Not to confused with Thingiverse.
Since printers are printing in 3D for now, it's better to think in advance:)
I've heard that from somewhere. It's a play on the word "filament"
Oh, Just as a heads up, I can think of the weirdest names...
