Spectrum PET-G Premium is the 2nd most popular 3D printing material, renowned for its zero shrinkage and low moisture absorption. It's long-term stability provides reliability. Boasting the benefits of both PLA and ABS, it offers an easy, reliable printing experience with superior layer adhesion and, if printed with transparent colors, near-transparency at a few outer perimeters. Certified safe for contact with food, its good creep resistance and chemical resistance make it perfect for items relying on dimensional accuracy and stability, such as gear wheels and slide bearings in an aqueous environment. It's also great for semi-transparent enclosures and backlit sections of signs.
