PETG (polyethylene terephthalate) is a copolymer of PET. Therefore, PETG exhibits superior transparency, durability, processability, shrinkage resistance, dimensional stability, and chemical resistance. PETG does not require very high printing plate temperatures, resulting in excellent print quality and detail. It can also be fiber-reinforced and used in applications such as engineering design, prototyping, functional testing, parts assembly, toys, and decorative items.
