PETG is the most commonly used form of PET (Polyethylene Terephthalate), with the G version being a glycol-modified PET, which is a widely used industrial thermoplastic. PETG has strong, durable properties and good heat resistance just like ABS, but easier to print. Parts printed with PETG are not only widely used in the prototyping stage of product development, but also in later stages of function testing and parts assembly. Printed PETG parts have been successfully used in the manufacturing application with or without post-finishing.
