It is the same food safe PET thats used in water bottles etc
It does not shrink or warp as easily as Abs does, & thus provides good dimensional accuracy for beginners who want to move up from PLA+.
Esun PETg 1Kg 1.75mm Translucent Grey – it is very dark but emits light. This colour looks like Titanium.
It provides excellent finish, high tensile strength, & has a high Glass Transition Temperature of 80 deg C.
