Compatible with all Creality K1 and K1C and new versions of K1 Max High thermal conductivity, uniform heating 360° ceramic heater improves heating efficiency, ensures more uniform heating and faster heat transfer. Effective cooling for easy printing Cooling part with split design reduces heat transfer, while the red copper heat sink increases cooling efficiency. High flow rate, support for high-speed printing Enlarged nozzle chamber achieves a maximum flow rate of up to 32 mm³/s and allows printing at high speeds up to 600 mm/s. All-metal integrated design for quick assembly and disassembly Nozzle and heat break part are made of an all-metal integrated design, facilitating quick disassembly and convenient replacement. Improved material, suitable for printing various filaments The heat break part is made of titanium alloy, which reduces thermal conductivity. The nozzle is composed of copper alloy and hardened steel, which supports printing various types of filaments.
