Official Creality K1 Nozzle Kits, 5PCS Ender 3 V3 KE 3D Printer Hardened Steel Nozzles 0.4mm, High-Speed Printing and High Flow Extruder Nozzles for Creality K1, K1 Max, CR-M4, CR-10 SE 3D Printers

Premium Quality - 5PCs high-quality hardened steel K1 nozzle kit, provide high-speed printing up to 600mm/s, for Creality K1/CR-M4/CR-10 SE/Ender 3 V3 KE 3D Printer. Good abrasion resistance, heat resistance, and corrosion resistance. It is convenient for you to replace them in time to achieve high-quality printing.
High Speed Printing - The hardened steel has a high thermal conductivity rating of 22W/m. k, high temperature resistance up to 450°C, requires high flow rate for high-speed printing.
Premium Performance - The hardened steel is heat resistant up to 450°C, which adopts advanced heat treatment process, and the Mohs scale hardness reaches 7.8, which extends the service life of the high speed printing nozzles.
High Precision - Ra <0.4, smooth inner wall, the inner wall enhances the flowability of filament and makes the extrusion smoother, no burr on the orifice makes the feeding of the filament smoother and no leakage, the flat surface and tight connection effectively solves the problem of filament leakage.
Wide Compatibility - The 3D Printer Hardened Steel Nozzles is suitable for most FDM materials such as PLA, ABS, PETG, TPE, TPU, PC, etc., and composite filaments with grinding additives such as carbon fiber, glass fiber, steel, wood, boron carbide, tungsten, phosphorescent pigments, etc.
