Modified polyethylene terephthalate glycol - PET-G is an amorphous thermoplastic copolyester that has excellent strength and optical properties. PET-G filament is designed primarily for professional 3D prints with FDM technology. It‘s more flexible and softer than PLA or ABS filaments. It has very low shrinkage and excellent layer adhesion, making it suitable for large-area 3D prints. PET-G is highly chemically resistant to acids and produces no unpleasant odour during printing. That's why 3D printing with Swift PET-G is so enjoyable! Another indisputable advantage of this filament is its recyclability.
