This extruder hotend kit is an original part for Creality Ender 3 V3 SE 3D printer. It has been pre-assembled with wires directly connected, enabling quick replacement. Features a high-precision thermistor with temperature detection up to 260C. Say goodbye to clogging: The combination of heating block and heat dissipation block ensures efficient heating and effective heat dissipation, reducing clogs and improving print success rate. Rapid heat dissipation: Irregular wave structure design increases the effective heat dissipation area for faster cooling. All-metal construction enhances overall performance. A silicone cover is included to help maintain stable temperatures on the Ender 3 V3 SE hotend, resulting in improved print quality and consistency. Compatibility: Ender-3 V3 SE Nozzle size: 0.4mm Voltage and power: 24V 40W Color: Silver Material: Aluminum alloy, brass, stainless steel Package contents: 1 x Hotend Kit Note: Light reflection and different display settings may cause slight color variations between the image and the actual item.
