PETG (polyethylene terephthalate glycol)
The PETG material is essentially the same as the known PET material from which PET bottles are made. The G in the acronym PETG stands for Glycol which is added during the manufacturing process. Glycol modifies the properties of PET so that it’s easier to print and less brittle. It is a strong and tough material, which is characterized by good thermal stability. Thanks to the small shrinkage during printing, it is suitable for printing large objects. PETG has mechanical and thermal properties better than ABS and bearing the printing properties of PLA.
