An amorphous copolymer in the polyester family made by combining PET (Polyethylene terephthalate) and glycol. The addition of glycol reduces the brittleness of PET on its own. It is hard, impact-resistant, chemically resistant, transparent, and ductile. It is also approved for use with foods.
In additive manufacturing, it is a popular filament material for fused deposition modeling as a transparent, strong material. Carbon fiber can be added to increase stiffness and strength.
It is abbreviated as PETG.
