The Creality K1 Max High Flow Nozzle Kit is designed to optimize your 3D printing experience. The kit includes nozzles that promote fewer disturbances, lower filament viscosity, and even filament feed, resulting in exact finishes on final prints. These nozzles feature a smooth feed bevel with a round opening to reduce friction resistance of the filament. The international standard brass nozzles have a 0.4mm diameter and provide good thermal conductivity and high strength, ensuring compatibility with Creality K1, K1 Max, and CR-M4 models.
