Machine-learning-rendered image of a flame and its 3D-printed fabrication. Credit: Markus Buehler Buehler pondered whether this approach could be expanded enough to study fire.

He 3D printed a KellyKettle. They've been around in multiple forms since the 1800's. I have two, one stainless and one aluminum, and both heat a comparable amount o f water faster than my home range.

The nozzle, the only 3d printed part even close to the flame, actually gets frozen, not heated. Also I use maker-geek PLA which is literally in that video as not being flammable.

3D printing prototype enclosures with PLA or PETg is quick and easy, but to which filament to you turn if the enclosure has to be installed somewhere, and therefore need to be flame retardant. Such ...
