This Creality 3D K1C/K1 Max nozzle is an original replacement part for Creality. The heat break is made of a titanium alloy, which helps reduce heat conduction. The nozzle, on the other hand, has good conductivity and better performance thanks to the material it is made of: TC4, SKD11 and a chrome + zirconium + copper alloy. This allows you to easily print filaments such as PLA, ABS, PETG and TPU. The nozzle is designed to be easily installed and replaced. In addition, the design also helps to make model printing smooth and stable, without filament leakage. Finally, you can print high-speed with this nozzle at a speed of 600mm/s. This product is suitable for the following Creality 3D printers.
