Features: 1Reliable Material: The full hotend kit is made of aluminum alloy and ABS, which is high temperature resistance, high abrasion resistance, strong load capacity, sturdy and durable. 2Integrated Structure: Integrated structure and simple circuit are convenient for disassembly, repair and assembly. This is covenient for you to use. 3Effective Heating and Cooling System: There are heating blocks and heat sinks. Heating block with insulating silicone housing keeps the temperature stable and makes the pressure evenly. The dual fan design makes the heat dissipation more even, model fast, tight and accurate printing. 4Thermistor and Heating Tube: Excellent thermistor and heating tube have a temperature of up to 260 C, with a rapidly rising temperature, accurate temperature control and good stability. 5Optimized Design of Heatbreak: Optimized design of heatbreak decreases the loss of heater block temperature by reducing heat conduction, and at the same time, it transfers its temperature to the radiator, which ensures the production stability. Item Type: Full Material: Aluminum alloy and ABS Voltage: 24V Applicable Models: For Ender 3 V2 Cooling System: Heating block, radiator, double fan Package Included: 1 x Full
