Polyethylene Terephthalate (PET/PETG)

The relative property levels of PETG.

PETG (Polyethylene Terephthalate) is a commonly use filament FDM 3D printing. It is a more durable version than PLA so can be used in higher impact strength related prototypes. Notably, PETG is used commonly in the Take-a-T Make-a-T project at the MILL.

The atomic structure of PETG.
