915 Generation 3Pcs K1 Nozzle Kit Hardened Steel 600mm/S High-Speed Printing for K1 / K1 Max / CR-M4 3D Printer Black 0.4/0.6/0.8mm

for High Speed Printing: The thermal conductivity of hardened steel is as high as 330W/m·k, ensuring that the nozzle is heated more evenly. The volume is twice as large as ordinary nozzles, supporting high-speed printing speed of 600mm
Uniform Nickel Plating, Smoother Extrusion: The nickel-plated layer on the surface greatly reduce the adhesion of filaments to the nozzle and smoother extrusion. x Applicable to most FDM materials such as PLA, ABS, PETG, TPE, TPU, PC, etc., And PEEK, PEKK, PEI, PSU, PPSU and other high temperature filaments
Hardened Steel Resists Corrosion for Longer Service Life: Advanced heat treatment process and better anti-oxidation are combined to prolong the service life of the nozzle Applicable to 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.
Premium Materials Handle High Temperature Filaments: Ensure fast heating of the high-temperature filaments and continuous printing x Copper alloy high temperature resistance up to 500°, hardened steel high temperature resistance up to 450°
