High-flow Prusa Nextruder nozzle for faster printing and longer wear life

The E3D High Flow ObXidian® 500 nozzle for Prusa Nextruder™ is a drop-in replacement nozzle built to increase material throughput while maintaining dependable extrusion. It is designed for users who want higher flow rates, better durability, and cleaner performance when printing both standard and abrasive filaments.

This nozzle combines an internally optimised high-flow design with a hardened ObXidian® 500 construction, making it suitable for faster print settings, thicker layers, and demanding materials that would wear standard nozzles more quickly.

Key features of the E3D High Flow ObXidian® 500 nozzle

• Higher volumetric flow: Internally optimised melt-zone geometry improves heat transfer and supports smoother filament melting, delivering substantially higher volumetric flow than standard nozzles.
• Built for abrasive materials: The hardened ObXidian® 500 construction, protective coating, and low-adhesion finish provide strong abrasion resistance for carbon-fibre, glass-fibre, metal-filled, and glow-in-the-dark filaments.
• Cleaner extrusion: The coated non-stick surface reduces plastic build-up to help minimise stringing, oozing, clogging, and nozzle jams.
• Long-run reliability: The wear-resistant design supports extended nozzle life and more consistent performance during long or high-speed print runs.
• High-temperature capability: The nozzle is rated to withstand elevated temperatures, depending on the printer and enclosure setup, for broader material support.
• Direct Nextruder™ fit: The nozzle is made specifically for Prusa Nextruder™ systems as a straightforward replacement without extra hardware changes.

Where a high-flow hardened nozzle makes the biggest difference

The E3D nozzle is well suited to high-speed printing with standard materials such as PLA, PETG, and ABS when the goal is to reduce print time while maintaining extrusion consistency. The increased flow capacity also helps when using thicker layers for faster functional prints and prototypes.

For composite and abrasive filaments, the hardened and coated design helps reduce wear compared with standard nozzles. That makes the nozzle a practical choice for carbon-fibre blends, glass-fibre materials, metal-filled filaments, and glow-in-the-dark compounds.

Large models, long-duration jobs, and production-style printing also benefit from the reduced build-up and lower maintenance requirements. Users looking for a simple Prusa Nextruder™ nozzle upgrade can use this option to unlock higher throughput and improved durability without changing the rest of the printer setup.
