Features: Experience seamless 3D printing with the advanced Hotend Kit, designed for optimal results. This metal Hotend Kit includes a durable nozzle and heatbreak with PTFE tubing, ensuring smooth filaments flow and preventing clogs. The cable length is 1.4meters, which is a direct original replacement for Ender3 V2Neo and Ender3Neo 3D printers. If applied to the Ender3 neoMax printer, you may need to extend the cable length to 1.5meters The extruder hotend kit is pre installed with a 100kNTC thermistor, a 24V 40W heatingelement, and a stainless steel insulation board with straight through holes. A single piece bimetallic heat exchanger will be provided in this package, which is made of two components: copperand titaniumTC4. TitaniumTC4 reduces the upwards heat conduction at the heating position, while copper is used for heat dissipation to accelerate heat conduction.
