PETG is short for polyethylene terephthalate glycol-modified and is a transparent type of Copolyester. PETG is the perfect filament to combine strength and ductility, which is why it’s used in so many mechanical parts and robotics. It has great chemical resistance with good water, acidic and alkalic resistance. PETG is food and skin safe, so it can be used in medical and food applications. In medical applications, it stands up to radiation and chemical sterilization techniques without changing color.
