PET-G is the most versatile plastic for 3D printers. It is characterized by high resistance to chemicals and solvents. It has a low shrinkage rate when cooled and therefore the products maintain high dimensional accuracy. Thanks to this, it is also suitable for printing larger sizes, which is difficult, for example, with ABS or ASA. It is not suitable for more temperature intensive applications due to operating temperatures arround 70 ° C.
