High Flow Creality Unicorn ObXidian Nozzle, 0.4 mm

E3D High Flow ObXidian Unicorn Nozzle 0.4 mm – Creality K1C / K1 Max / Ender 3 V3

The E3D High Flow ObXidian Unicorn Nozzle is a premium high-flow nozzle developed in collaboration between E3D and Creality. This high-performance nozzle is specifically designed for Creality K1C, K1 Max, and Ender 3 V3 / V3 Plus 3D printers, offering significantly higher flow rates and improved performance for high-speed 3D printing.

Thanks to the unique multi-channel High Flow design, filament is distributed across multiple internal channels, increasing the contact surface area with the filament. This results in a significantly higher volumetric flow rate and enables print speeds of up to 600 mm/s.

The nozzle features an integrated all-metal nozzle and heatbreak, which provides better heat control and prevents filament leaks. Additionally, the E3DLC coating provides extra wear resistance and an anti-stick surface, significantly reducing plastic buildup around the nozzle.

Key features

High Flow design
Thanks to E3D's multi-channel design, the filament is guided through four internal channels. This significantly increases the volumetric flow and enables print speeds of up to 600 mm/s.

Up to 65% higher flow rate
Compared to standard nozzles, this high-flow nozzle can increase filament throughput by more than 65%, ensuring faster printing without sacrificing quality.

ObXidian wear resistance
The nozzle combines a hardened steel insert with the special E3DLC™ coating, ensuring extreme wear resistance and an anti-stick surface.

Suitable for abrasive filaments
Perfect for printing fiber-reinforced materials such as carbon or glass fiber filaments.

Titanium HeatBreak
The integrated titanium heatbreak ensures a sharp thermal separation and reduces the risk of heat creep.

Fast installation
The nozzle is designed for easy replacement and can be installed in less than 5 minutes.

Frequently Asked Questions (FAQ)

Do I need to recalibrate the print bed after replacing the nozzle?

Yes, it is recommended to always perform an Auto Bed Leveling after installing a new nozzle. You can do this via the “Self-check” option on your printer. This recalibrates the print bed and ensures optimal print quality.

Are there other nozzle diameters available for the Creality ObXidian High Flow nozzle?

At the moment, there are no confirmed plans for additional nozzle diameters. It is possible that more variants will be available in the future. Keep an eye on updates from the manufacturer.

What is the maximum print temperature of this nozzle?

The E3D ObXidian Unicorn High Flow nozzle is designed for a maximum temperature of 300°C. This makes the nozzle suitable for a wide range of standard and engineering-grade filaments.

Will this nozzle shorten my print time?

In many cases, this high-flow nozzle can reduce print time, especially for larger models or prints with a higher volumetric flow.
However, the exact time saved depends on various factors, such as:

• the type of model

• slicer settings

• the amount of infill

• the chosen print speed

For very small or detailed models, the difference may be less significant because the slicer prioritizes the quality of the outer layers.
