Pet-G is very good functional material & its easier to work with than Abs.
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+.
It provides excellent finish, high tensile strength, & has a higher Glass Transition Temperature of 70 deg C.
It is highly recommended for those who want high temperature & high strength properties compared to PLA.
