The Unicorn Quick-Swap Nozzle is a high-performance, integrated extrusion component specifically engineered for the Creality K2 series. This all-in-one design combines the nozzle and heat break into a single unit, delivering professional-grade reliability and thermal efficiency.
The “Unicorn” design solves the most common issue in 3D printing: internal leaking. By integrating the nozzle and the heat break into a single continuous piece, it eliminates the threaded interface where filament often leaks when not properly hot-tightened. This ensures a leak-proof performance and significantly simplifies the maintenance process.
Features:
- The 0.4mm orifice is crafted from hardened steel, providing exceptional wear resistance for abrasive filaments like Carbon Fiber, Glass Fiber, and Metal-filled PLA.
- The main heating zone is constructed from high-conductivity copper alloy, ensuring rapid heat-up times and consistent flow during high-speed printing.
- The upper neck uses titanium alloy to provide superior thermal isolation, effectively preventing “heat creep” and preventing clogs in the cold end.
- Designed for the K2 Pro’s rapid-maintenance ecosystem, this nozzle can be swapped out quickly, reducing downtime between different projects or material changes.
- The internal bore is polished to a mirror finish, reducing friction and allowing for the high-volume extrusion required by the K2 series’ impressive print speeds.
