Quick-Swap: Unicorn integrated nozzle is suitable for Creality K2/ K2 Pro/K2 Plus/ Hi Combo. The nozzle and heat break adopts an all-metal integrated design, facilitating quick disassembly and convenient replacementUpgraded Material for More Filaments: The heat break is made of titanium alloy, which can effectively reduce heat conduction. The nozzle is made of hardened steel (SKD11) material, with a Moh's hardness of 7.8, to provide a sixfold lifespan, high thermal conductivity, high hardness, better performance. Support PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, PET-CF multiple filaments printingHigh-flow High Speed Printing: Enlarged nozzle chamber,achieving a maximum flow rate of up to 30mm³/s, and supporting high-speed printing at 600mm/sPrecision Craftsmanship: Joints fit tightly and effectively prevent filament leakage. Inner hole roughness Ra 0.4, ensuring smooth filament feeding. No burrs at the opening, stable printing with reduced clogging
