Polyethylene Terephthalate Glycol (PETG) is a water clear material and designed to be very 'easy to use' in a range of applications. It's a thermoplastic polymer created through the copolymerization of PET and ethylene glycol.
PETG has good temperature resistance, is durable, and easy to print with. There is good layer adhesion which reduces deformation during printing. PETG has a great resistance to chemicals (bases and acids), corrosion to oxidizing agents, wear and impact.
