Nozzle set for Creality K1C. All-metal construction. High flow rate for high-speed applications. Nozzle diameters: 0.4 mm, 0.6 mm, 0.8 mm. Filament diameter: 1.75 mm. The Unicorn quick-change nozzle from Creality features a quick-swap tri-metal construction consisting of a nozzle and a heat break for easy installation and removal. Thanks to an enlarged nozzle chamber, the Unicorn nozzle achieves a maximum flow rate of up to 30 mm³/s. This all-metal construction supports high-speed printing of up to 600 mm/s. The heat break is made from a robust titanium alloy to reduce heat conduction, while the nozzle itself is made from a copper alloy with a thermal conductivity coefficient of 330 W/mK. The nozzle tip is made from hardened steel with a Mohs hardness of 7.8. Due to the improved materials, a wide variety of filaments are supported, including PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, and PET-CF.
