Creality Unicorn K2 Plus Quick-Swap Nozzle

In a market where efficiency and user experience make the difference, the new Unicorn quick-change nozzle, specifically designed for the Creality K2 Plus, emerges as an intuitive and professional solution. Designed for those who want to streamline their printing processes hassle-free, this system redefines simplicity by allowing for a quick, safe, and tool-free nozzle swap. Its design optimizes the daily workflow, reducing downtime and increasing productivity in demanding environments.

Advanced technical features.

The Unicorn quick-change nozzle features a full metal tri-metal construction, composed of a high-conductivity copper body (330 W/mK), hardened steel tip (Mohs hardness 7.8), and a titanium alloy heat break to minimize thermal transfer to the heatsink. Thanks to its enlarged internal chamber, this design enables a maximum flow rate of up to 30 mm³/s, allowing for high-speed printing of up to 600 mm/s with the Creality K2 Plus. It is also available in multiple diameters (0.2 mm, 0.4 mm, 0.6 mm, and 0.8 mm) and is compatible with 1.75 mm filaments such as PLA, ABS, PETG, TPU, PP, PC, and variants reinforced with carbon fiber or PET.

Benefits in daily use.

The quick-mount structure (nozzle integrated with heat break) enables fast and safe nozzle swaps, even when cold, avoiding downtime and simplifying maintenance. The polished internal surfaces (roughness Ra 0.4–0.5) significantly reduce clogging, ensuring consistent filament feed. The precision machining eliminates burrs, providing leak-proof connections between the heat break and heater block, reducing leakage and improving finish quality.

Competitive advantages over traditional nozzles.

By integrating the nozzle and heat break into a single unit, it offers greater operational reliability compared to conventional Volcano systems, avoiding filament loss during reassembly and enabling quick changes without additional tools. The combination of copper, hardened steel, and titanium ensures increased durability and wear resistance, especially when printing with abrasive filaments, reducing the cost per hour of use. Additionally, it saves time and improves the overall user experience.
