  [1] |  | Heat-Resistant Nozzles  Some materials, such as PEEK, Ultem, and polycarbonate, require printing temperatures above 300°C. Standard brass nozzles degrade under such conditions, so heat-resistant nozzles made from hardened steel, tungsten, or ruby tips are necessary. These nozzles withstand extreme temperatures and abrasive filaments, extending the lifespan of the hot end. |
