[High quality]This K1C Ceramic Heating Block Kit is compatible with K1C /k1for high-speed printing. 360 surround ceramic heater improves heating efficiency, more uniform heating and faster heat transfer. It can be heated to 200C in 40 seconds. [High Speed, High Flow]- Thanks to the hot melt section length being enlarged, K1C hotend supports 600mm/s high-speed and 32mm/s high flow printing. Furthermore, 360 surround ceramic heater improves heating efficiency, and more uniform heating. It can be heated to 200 in 40 seconds. [All-metal Integrated Design]- The nozzle and heat break adopt an all-metal integrated quick-swap design, facilitating quick disassembly and convenient replacement. [Upgraded Material]- The heat break is made of titanium alloy, which reduces heat conduction. The nozzle is composed of copper alloy and hardened steel, supporting the printing of filaments, such as PLA, ABS, PTEG, TPU, PP, PC, PLA-, PA-, PET-, etc. [Easy to install]The nozzle and heat break adopt an all-metal integrated design, facilitating quick disassembly and convenient replacement. Smooth inner walls and no blockage, inner hole roughness RaLess than 0.4, ensuring smooth filament feeding.
