PETG (Polyethylene Terephthalate Glycol)
Chemically inert, high-strength and more temperature resistant than PLA. Suited for functional parts that do not require high temperature resistance.
Tough and impact resistant
Good UV and chemical resistance
Low warping, reliable prints
Technical specifications
PETG (polyethylene terephthalate glycol‑modified) is a tough, semi‑crystalline thermoplastic that balances strength, ductility, and chemical resistance. With a glass‑transition temperature around 75–85C, PETG is more heat‑tolerant than PLA while being cheaper than engineering filaments like PA6, PA12 and PAHT. It prints with a glossy finish and is available in a semi-translucent variants.
