While commodity plastics and engineering plastics can typically maintain their performance in environments up to 100°C and up to 120°C, respectively, a high-performance thermoplastic can withstand continuous use temperatures of 230°C. Molding these high-temperature thermoplastics requires processing equipment capable of melt temperatures up to 400°C and mold temperatures up to 200°C. It typically works best with a nozzle temperature between 360–400°C and a heated bed of 120°C.
