3D printing PETG

PET-G – Polyethylene terephthalate

PETG’s close relative, PET, is famous because of plastic bottles. PET-G is impact resistant, slightly flexible, remarkably resistant to chemicals. PETG is also one of the few foodsafe 3D filaments. PETG is a great choice for mechanical parts, that require slightly higher impact and stress resistance. 3D Printing PETG is similarly easy to PLA, but requires better, more expensive machines. Visually, PETG prints with small details look a tiny bit worse than PLA. Carbon fiber infused or fire retardant PETG filaments are also available with us.
