E3D High Flow ObXiDian 500 Prusa Nextruder Nozzles for Prusa MK4, XL, CoreOne etc.

Prusa MK4, XL, and CoreOne users pushing for higher print speeds often face nozzle wear and flow limitations that reduce print quality and increase downtime. Without a high-performance nozzle, abrasive filaments can quickly degrade standard brass nozzles, causing clogs and inconsistent extrusion.

The E3D High Flow ObXiDian 500 Prusa Nextruder Nozzle is engineered specifically for Prusa Nextruder hotends on models including the MK4, MK4S, XL, CORE One, and CORE One L. Featuring ObXiDian® 500 technology, this tool-steel nozzle with E3DLC™ coating offers up to 5 times the wear resistance of previous ObXiDian nozzles, making it ideal for abrasive materials like carbon fiber and glass fiber filaments. Its unique 4-channel internal geometry enhances heat transfer and volumetric flow rate, enabling faster print speeds without sacrificing surface finish or strength. The low-surface-energy coating reduces plastic build-up, minimizing print failures and maintenance.

Why Upgrade?

• Prusa MK4 and XL users can maximize their printer’s motion system with increased volumetric flow for faster, high-quality prints.
• ObXiDian 500 technology extends nozzle life significantly when printing abrasive filaments like carbon fiber and glow-in-the-dark materials.
• Low-surface-energy coating reduces filament build-up, preventing clogs and print failures common in high-speed printing.
• Seamless drop-in replacement for Prusa Nextruder hotends requires no hardware modifications or complex installation.
• Supports future-proof printing with a temperature rating up to 500°C for advanced engineering materials.

Best For:

• Prusa MK4 and MK4S owners upgrading to high-speed, abrasive filament printing.
• Prusa XL users seeking improved flow rates without sacrificing print quality.
• CORE One and CORE One L builders requiring durable nozzles for extended print runs.
• Enthusiasts printing carbon fiber, glass fiber, or glow-in-the-dark filaments on Prusa Nextruder setups.
• Users wanting a hassle-free nozzle upgrade with no changes to existing hardware or cooling ducts.

Pair With the Right Filament

Unlock the full potential of your Prusa printer by pairing this nozzle with filaments designed for high performance and durability.
