PETG filaments use odorless PETG raw materials that meet the food contact requirements, with a heat resistance temperature of 70-75℃. Compared with ABS, it has odorless characteristics, high bonding strength, low warping edge rate, etc., and the products are suitable for structural parts. PETG filaments are suitable for 3D printers with high printing temperature, especially for 3D printers with 0.5-0.6mm nozzles.
