This extruder hotend kit is part from for 3 V3 SE 3D printer. It has been assembled in advance and 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 effective heat dissipation area and realizes fast heat dissipation. All-metal design for better overall performance. Bimetal Throat + Copper-plated nozzle: has a better overall performance with ability to accelerate heat dissipation. Silicone Cover is provided to help keep temperatures on for 3 V3 SE hotend much more stable and this result in higher print quality and consistency.<br><br>Compatible for -3 V3 SE Size of nozzles:0.4mm Voltage and Power: 24V 40W Color: silver Material: aluminum alloy<br><br>Package Contents: 1 x Hotend Kit<br><br>Only above package content, other products are not included.
