PETG description

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. PETG offers good impact resistance, layer adhesion, and can be exposed to water, many acids, and alcohols, which makes it well‑suited for functional parts, enclosures, and outdoor components that see moderate heat and stress. It also prints with a glossy finish and is available in a semi-translucent variants.
