Hardened Steel Nozzle A hardened steel nozzle is a high-durability nozzle designed to withstand abrasive filaments, such as carbon fiber, glass-filled nylon, and metal-infused materials. Unlike standard brass nozzles, which wear out quickly with these filaments, hardened steel nozzles maintain their shape for extended periods. However, they have lower thermal conductivity, requiring slightly higher printing temperatures. They are essential for industrial and high-strength 3D printing applications where material abrasion is a concern. |
