Features 1、Upgraded Heating Block And Nozzle Tube: The 3D printer hotend replacement kit features an advanced heating block made from Cr Zr copper with Ni plating, allowing for rapid heat conduction and high temperature printing. This upgrade ensures consistent temperature regulation for exceptional print quality, making it suitable for various filament types. 2、Enhanced Thermal Performance: The Ti alloy nozzle tube is wrapped with a Cr Zr copper ring, improving heat dissipation efficiency. With a wall thickness of only 0.25mm and an internal finish roughness of Ra 0.4, this design minimizes the risk of clogs while enhancing the overall thermal stability of your printing process. 3、High Speed Printing Capability: The special volcanic design of the assembled hotend kit ensures even heat distribution across the print head. The internal smoothness of the nozzle reduces air resistant and prevents material clogging, enabling you to achieve high speed printing without compromising on quality. This design is suitable for fast production and intricate designs. 4、Simple Installation Process: Switching to the assembled extruder 3D printer hot end kit is easy. Simply remove the old hotend and install this new one to get started. The heating part, thermistor, and nozzle are preinstalled, allowing you to save time and effort on setup and focusing on your innovative projects immediately. 5、Rugged Design: The ceramic upgrade in the extruder head provides excellent insulation and high temperature resistant while preventing erosion and wear. This feature ensures that the hotend remains good and performs optimally over extended periods.
