High-flow Creality nozzle for faster printing and abrasive filament use

The E3D Creality High Flow ObXidian Unicorn Nozzle is a performance upgrade for Creality high-speed 3D printers that delivers higher flow, better wear resistance, and more consistent output. Developed by E3D in partnership with Creality, this nozzle is built for the K1C, K1 Max, and Ender 3 V3/Plus.

The Unicorn nozzle combines high-flow internal geometry with a wear-resistant ObXidian™ surface, making it suitable for users who want to print quickly without giving up durability when running abrasive materials.

Key features of the ObXidian High Flow Unicorn Nozzle

High-flow internal geometry for fast extrusion

E3D’s multi-channel internal geometry supports flow rates up to 52 mm³/s. That added melt capacity helps the nozzle keep up with print speeds up to 600 mm/s while maintaining strong interlayer adhesion and solid print quality.

ObXidian™ coating for abrasive filament durability

The hardened ObXidian™ coating is designed to resist wear from demanding materials. This makes the nozzle a practical choice for carbon fibre, glow-in-the-dark, and metal-infused filaments that can quickly wear standard brass or steel nozzles.

Tri-metal construction for thermal stability

The nozzle uses a titanium HeatBreak for thermal isolation, a hardened tool steel core for strength, and the ObXidian™ coating for surface durability. This tri-metal design helps reduce heat creep, preserve cold-end control, and support stable printing conditions.

Integrated HeatBreak for simpler maintenance

The integrated HeatBreak design is made for Creality Sprite-style extruders and enables tool-free installation in under 5 minutes. Faster nozzle changes make routine maintenance easier and reduce downtime between material or nozzle swaps.

Where this Creality high-flow nozzle fits best

• High-speed everyday printing: suited to users pushing Creality printers to higher throughput while aiming to keep print quality consistent.
• Abrasive filament projects: useful for carbon fibre, glow-in-the-dark, and metal-filled materials where nozzle wear is a common issue.
• Functional parts and production runs: the combination of flow capacity and wear resistance helps support longer print sessions with less interruption.
• Maintenance-conscious setups: the tool-free, under-5-minute installation process is well suited to users who want quicker servicing on compatible Sprite-style systems.
