Feature: 1. SUITABLE FOR MULTI CONSUMABLE PRINTING: The pipe is made of Ti alloy and copper material, the front end is heat insulated, the back end reduces heat conduction upward, the nozzle is made of brass, possess high accuracy, good thermal conductivity, glossy inner wall without burrs, high speed and high flowrate printing 2. HIGH SPEED AND STABILITY: The heating block material is copper plated heating block, high hardness, good thermal conductivity, prevent high temperature; The heating rod is upgraded to a ceramic heating body, which can be heated quickly and stable without cooling at high speed 3. FASTER PRINTING EXPERIENCE: The extruder hot end kit is pre assembled and you just plug in the wires. Applicable to for Ender 3V3 SE models. Printing speeds of up to 250 mm/s are faster than most printers on the market. You can finish the model efficiently, saving time waiting for print jobs 4. PREVENT HIGH TEMPERATURE: Can withstand high temperatures of up to 300℃ to achieve better high temperature consumables printing effect. For Ender 3 V3 SE hot end heating block parts are compatible with various filaments, such as PLA, ABS, PETG, TPU, PP, PC, nylon, etc. 5. FAST HEAT DISSIPATION: The heating block is made of copper plating and the nozzle is made of brass, which effectively insulates heat and heat dissipation, reduces blockage and improves printing success rate, and is easy to install. The roughness of the inner wall of the nozzle is Ra0.3 to improve the printing quality Specification: Item Type: Ceramic Heater Block Hot End Kit Heater Block Material: Copper plating Nozzle Material: Brass Heatsink Material: Ti alloy and copper Standard Nozzle Diameter: 0.4mm Tube Wall Thickness: 0.25mm Tube Insulation Distance: 1.2mm Tube Inner Wall Roughness: Ra0.4 Thermal Sensitivity: 100K Maximum Temperature: 300℃ Heating Plate: Ceramic heating plate, 24V, 60W Extrusion Flowrate: 33mm³/s.
