PET-G

PET-G filament for 3d-printing (also known as Co-PET)

This type of plastic can be sometimes harder to print, especially when using on cheaper printers with open frames and simpler mechanics, or might require some time to fine-tune some printing parameters. In change for this, you can get better layers adhesion, higher strength, and flexibility, as compared to ABS.

What's also important, is that this kind of plastic is totally safe to use at home - it makes almost no smell and produces no toxic elements into your room.
