Feature: 1. Upgrade Hot End Kit: The hot end structure features an upgraded design with stepped limits added to the interface with the heating block, effectively solving issues of material leakage and detachment 2. Heating Block and Nozzle: The heating block uses CrZr copper ni coating for high temperature printing and rapid heat conduction. The nozzle is made of SKD11 quenched steel, 550℃ temperature resisting, ensuring durability 3. Threaded Connection: The heating block and insulation plate are connected using thread, preventing detachment and allowing for easy disassembly and replacement, which reduces operational costs 4. Efficient and Stable: The inner wall roughness of the heatbreak and nozzle is Ra0.4, minimizing clogging and enhancing print. The heatbreak and the heat sink is fixed with 2 hex screws for stability, removable and replaceable 5. Compatibility: This hot end kit is specifically designed for X1C 3D printer and is compatible with various printing materials, including PLA, ABS, PTEG, TPU, PP, PC, and nylon, ensuring versatility in printing applications Specification: Item Type: Hotend Kit with Fan Compatible Filament: PLA, PETG, ABS, PA, PC Applicable Model: For X1C 3D Printer.
