Upgrade your high-speed 3D printing setup with this hardened steel nozzle kit engineered for Creality K1, K1C, K1 Max and Ender 3 V3 series printers. Each nozzle and heat break uses an all-metal integrated design, so you can swap worn or clogged parts in seconds and get straight back to printing.

The enlarged melt chamber delivers a maximum flow rate of up to 30 mm3/s and supports print speeds up to 600 mm/s, making this kit a smart choice for fast, reliable extrusion on modern high-flow hot ends. Precision machining keeps the inner wall smooth, the orifice burr-free and the joints tight to prevent filament leakage.

• Brand: Xirbbo
• Type: Extruder Nozzle
• Material: Hardened Steel
• Color: Bronze
• Nozzle Aperture Options: 0.4 mm, 0.6 mm and 0.8 mm (see the drop-down menu for the option you need)
• Design: All-metal integrated nozzle and heat break for quick swap installation
• Maximum Flow Rate: Up to 30 mm3/s with support for printing speeds up to 600 mm/s

• ✓ Swap nozzles in seconds thanks to the quick-swap integrated design, no messy rebuilds needed
• ✓ High-flow chamber keeps up with fast print speeds for quicker, cleaner finished parts
• ✓ Hardened steel construction stands up to abrasive filaments far better than standard brass
• ✓ Tight joints and a smooth inner wall help prevent filament leakage and jams
• ✓ Burr-free orifice delivers stable extrusion and a smooth, detailed surface finish

Ideal for hobbyists and print farm operators running Creality K1 and Ender 3 V3 machines who want faster output and longer nozzle life. Choose a smaller aperture for fine detail work and a larger aperture for fast, high-flow prints with thicker layers.

Replacement is straightforward: power down and cool the hot end, remove the old nozzle and heat break, then install the new integrated assembly and re-level as required.
