PETG (Polyethylene Terephthalate Glycol-modified) is a popular 3D printing filament known for its durability, chemical resistance, and ease of use, combining PLA's printability with ABS-like strength. It is commonly printed at 230–260°C with a bed temperature of 70–90°C, offering a glass transition temperature around 75–85°C.
