Revo ObXidian High Flow Nozzle 0,4 mm

The E3D Revo ObXidian High Flow 0,4 mm high-flow nozzle is a top solution for E3D Revo system users who want to significantly speed up printing and frequently print abrasive materials. It combines special tool steel with an E3DLC™ coating, which ensures extraordinary wear resistance and a non-stick surface for a cleaner nozzle. Unlike standard brass nozzles, ObXidian handles long-term printing of carbon, glass, metal-filled, or glow‑in‑the‑dark filaments without rapid wear. The High Flow version also features modified internal geometry for higher heat transfer and a significantly higher volumetric flow rate – ideal for modern high-speed printers.

Main benefits

• High Flow Special internal channels increase the contact area with the filament and improve heat transfer, so you can print faster without losing quality.
• Extreme abrasion resistance Tool steel combined with the hard E3DLC™ coating offers resistance several orders of magnitude higher than conventional hardened steel nozzles. Suitable for:
  • carbon and glass fibers
  • metal-filled materials
  • abrasive PETG/ABS/ASA blends
  • glow / glow‑in‑the‑dark filaments (at reasonable speeds)
• Cleaner nozzle, less buildup The non-stick surface reduces the adhesion of molten plastic, so large drops and lumps that spoil the print surface do not form on the tip.
• Part of the Revo system – nozzle + heatbreak in one Each Revo nozzle is a pre-assembled assembly of nozzle + heatbreak. Replacement is fast, tool-free, and without hot tightening, eliminating the risk of leaks and oozing.
• Easy size identification The nozzle has the size 0,4 mm engraved on the body and is also supplied with a color-coded silicone sock (red for 0,4 mm), so size confusion is practically impossible.

Compatibility

Revo ObXidian High Flow 0,4 mm is designed for E3D Revo hotends:

• Revo Hemera / Hemera XS
• Revo Micro
• Revo Six
• Revo Voron
• Revo CR
• Revo Prusa MK3 / Revo Prusa Mini
• Revo Micro LGX
• Revo BIQU H2V2, BIQU Panda Revo
• and other compatible Revo variants

Warning: Revo nozzles are not compatible with classic V6 blocks and other non-Revo hotends.

Typical use

• high-speed printing of technical parts from PETG, ABS, ASA, PA, PC Blend etc.
• frequent printing of composite filaments (CF, GF, metal-filled, glow) without constant nozzle changes
• production printing of multi-hour jobs where flow stability and minimal downtime are key
• upgrade of a standard Revo assembly to a High Flow configuration

Recommendations for use

• Maximum nozzle temperature: up to 300 °C (according to E3D data for High Flow ObXidian)
• When switching to a High Flow nozzle, adjust the slicer profile (higher volumetric flow rate, appropriate acceleration and speeds).
• For extremely abrasive filaments (e.g., some PA with high fiber content or aggressive glow‑in‑the‑dark), monitor the nozzle condition and follow the filament manufacturer's recommendations regarding minimum nozzle diameter.

This nozzle is an ideal choice for users who want maximum speed and longevity from their E3D Revo hotend printer while printing a large amount of abrasive or demanding materials.

Key features:

• E3D Revo ObXidian High Flow high-flow nozzle with 0,4 mm diameter for the E3D Revo system.
• Extremely high abrasion resistance thanks to tool steel and E3DLC™ coating, suitable for abrasive filaments (CF, GF, metal-filled, glow).
• Modified internal geometry for higher volumetric flow rate and faster printing without compromising quality.
• Pre-assembled nozzle + heatbreak assembly – no hot tightening, minimal risk of leaks.
• Non-stick surface reduces plastic adhesion, the nozzle stays cleaner and improves the appearance of prints.
• Easy and fast nozzle replacement without tools, ideal for experimenting with different diameters.
• Compatibility with a wide range of E3D Revo hotends (Hemera, Micro, Six, Voron, CR, Prusa MK3/Mini and others).
