High Flow Nozzle Kit - Nozzle head made of hardened steel, Mohs hardness 7.8, long service life; The thermal conductivity of copper alloy is as high as 330W/m-k, ensuring that the nozzle is heated more evenly The volume is enlarged supporting a high-speed printing speed of 600mm/s.

Wear Resistance ＆ Heat Resistance - Copper alloy is heat resistant up to 500°C, while hardened steel is heat resistant up to 450°C.

No Clogging - Smooth inner wall without burr on the orifice for smoother feeding. With the Rac＜0.4 roughness, the inner wall enhances the fluidity of the filament and brings super smooth extrusion.

Tight Fit, No Leakage - A flat surface and intense joint effectively solve the leakage problem.

Multi-aperture Diameter Available - 0.4mm, 0.6mm, 0.8mm meets different requirements.

Wide Applicability- The High Flow Nozzle Kit is suitable for K1, K1 Max, Ender 3 V3 KE 3D Printers.
