Creality Official Ender 3 V3 KE Hotend, Ceramic Heating Block Kit with Bimetallic Material Nozzel 0.4mm*2, Upgrade Hotend 300℃ High Temperature 500mm/s speed for

【300°C High Temperature Resistance】Creality hotend nozzles 0.4mm are all-metal design consisting of a copper alloy and hardened steel that can withstand temperatures up to 300°C. The copper alloy nozzle has superb thermal conductivity, while the hardened steel nozzle is harder and more abrasion-resistant. Upgrade nozzles support high flow printing while ensuring hardness 【High Thermal Conductivity】Ender 3 V3 KE ceramic heating block upgrade kit adopts 360° surrounded ceramic heater to improve the heating efficiency and heating uniformity 【High Flow Printing】Enlarged hotend nozzle chamber with a maximum flow rate of 32mm3/s, supports high speed printing of up to 500mm/s. Creality Ender 3 V3 KE hotend has been upgraded compared to ordinary hotend. The extremely thin wall thickness of the heat break provides excellent heat insulation performance. Smaller roughness on the inner wall of the nozzle results in smoother material discharge and better printing results 【Easy to install】The high flow hotend has been assembled in advance, the wire is directly inserted, can be quickly replaced, shorten the work time-consuming, faster to realize the creative completion 【Compatibility】The high speed hotend is designed for the Ender 3 V3 KE and only works with this model. It is also compatible with most filaments such as PLA/ABS/PETG/TPU/PP/PC/PLA-CF/PA-CF/PET-CF
