From this (rejected) suggested edit:

There have been some new and interesting discoveries by Stefan Hermann on this subject; it seems that Hot Melt EVA Plastic can indeed be turned into a sort of Filament and used inside a 3d printer. This filament has to be oiled after melting as to not stick to itself and everything it touches.

After all of the conditions are met though it can be perfectly good to use in FDM 3D printers to make what you would normally make using one. although it is quite difficult to bridge and make overhangs due to the goopy nature of EVA.

More on this topic can be found in this ~19 minute video by Stefan Hermann of the CNC Kitchen YouTube channel:
