This extruder hotend kit is original-part from for Creality Ender 3 V3 SE 3D printer. It has been assembled in advance and the wires are directly plugged in, allowing for quick replacement. High precision thermistor, temperature detection up to 260.Say Goodbye to Clogging: Heating Block + Heat dissipation block, Highly effevtive heating and heat disspation, Fewwer cloggings, much higher printing success rate.Rapid Heat Dissipation: Irregular wave structure design increases the effective heat dissipation area and realizes fast heat dissipation. All-metal design for better overall performanceSilicone Cover is provided to help keep temperatures on the for Ender 3 V3 SE hotend much more stable and this will result in higher print quality and consistency.Compatible for: Ender-3 V3 SESize of nozzles:0.4mmVoltage and Power: 24V 40WColour:SilverMaterial:Aluminum alloy + brass + stainless steelPackage Contents:1 * Hotend KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
