Creality Official Ender 3 V3 SE Hotend, Ceramic Heating Block Kit with Copper Alloy Nozzle 0.4mm&0.6mm, Upgrade Hotend 250mm/s High Speed Printing for

【Innovative combinations】Creality hotend is equipped with two copper alloy nozzles, 0.4mm & 0.6mm respectively, to meet a variety of printing needs. The copper alloy nozzles have a uniform nickel plating, greatly reducing the adhesion of filaments to the nozzle and smoother extrusion 【Easy to Install】This extruder hotend kit is original part from Creality Ender 3 V3 SE 3D printer. It has been assembled in advance and the wires are directly plugged in, allowing for quick replacement 【Fewer Clogging】The Ender 3 V3 SE hotend is equipped with teflon tube, which is not plugged and ensures smooth feeding. The throat and nozzle are closely fitted with smooth inner wall, which is conducive to even material discharge and reduce drawing 【Rapid Heating】High thermal conductivity promotes rapid temperature rise. At the same time, insulation silicone cover close fit, not easy to slip off. Silicone Cover is provided to help keep temperatures much more stable to obtain better printing effect 【Efficient Heat Dissipation】The increase of heat dissipation blocks greatly improves the heat dissipation effect, avoids the impact of high temperature on printing, and ensures the quality of printing
