PETG (Polyethylene Terephthalate Glycol-modified) is a thermoplastic derived from PET (used in water bottles), modified with glycol for better printability.
It’s tough, impact-resistant, and less brittle than PLA.
Density: ~1.27 g/cm³
Glass transition temperature (Tg): ~80 °C
Melting temperature: 230–250 °C
Nozzle temperature: 230–250 °C
Bed temperature: 70–90 °C
Warping: Minimal compared to ABS, but bed adhesion is important.
Ventilation: Emits mild fumes, but far less than ABS.
