All-in-One Chrome Zirconium Copper Nozzle for Creality Ender-3 V3K1CK1 Max 3D Printers 1. Engineered for High-Efficiency & High-Speed Printing: This 3D printing nozzle is designed for high-efficiency and high-speed printing, compatible with Creality Ender-3 V3, K1C, and K1 Max models. Supports stable multi-material extrusion. 2. Full-Metal Integrated Throat Design for Quick Installation: Features a seamless full-metal structure for rapid assemblydisassembly and easy replacement. (Ensure the nozzle is fully cooled before manual replacement.) 3. High Flow Rate for Ultra-Fast Printing: Enlarged chamber design achieves a flow rate of up to 30mm3s, compatible with high-speed printing demands of 600mms. 4. Titanium Alloy Throat + Multi-Material Compatibility: The Titanium alloy throat effectively blocks heat transfer. The copper-steel composite structure supports PLAPETGABS and composite filaments. 5. Multiple Sizes (0.20.40.60.81.0mm) for Customization: Choose from various nozzle diameters to balance print precision and speed. 6. Leak & Clog Prevention Optimization: Internal wall roughness: Ra is less than 0.4, ensuring uniform extrusion and preventing clogging. Precision machining eliminates burrs, while tight interfaces prevent leaks. Specifications: 1. Material: Chromium Zirconium Copper + Hardened Steel 2. Dimensions: Length 65.4mm × Diameter 6mm 3.
