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

Prusa MK4, XL, and CoreOne users know that abrasive filament wear quickly degrades standard nozzles, causing print defects and frequent replacements that interrupt production. Without a durable nozzle, printing high-speed or abrasive materials risks nozzle erosion and poor surface finish.

The E3D ObXiDian 500 Prusa Nextruder Nozzle is a premium, high-flow hardened nozzle engineered in collaboration with Prusa for the Nextruder system. Designed as a direct drop-in upgrade for Prusa MK4, XL, CoreOne, and MK3.9 series printers, it features ObXiDian 500 technology that offers at least five times the wear resistance of standard hardened nozzles. Its advanced low-surface-energy coating prevents plastic buildup and nozzle gunk, ensuring cleaner prints and reduced maintenance even when printing abrasive filaments like carbon fiber, wood-fill, or glow-in-the-dark. The toolless nozzle change system enables quick swaps without modifications, maximizing uptime for high-speed, high-quality printing.

Why Upgrade?

• Prusa MK4 and XL users printing abrasive filaments benefit from dramatically extended nozzle lifespan with ObXiDian 500 technology.
• CoreOne and MK3.9 series owners reduce print failures caused by nozzle clogging and plastic buildup.
• High-speed Prusa Nextruder builds maintain consistent flow and surface finish with the high-flow design.
• Toolless nozzle swaps minimize downtime during maintenance or filament changes.
• Compatible with a wide range of filaments, enabling versatile printing without nozzle wear concerns.

Best For:

• Prusa MK4 and XL users upgrading to a hardened nozzle for abrasive filament printing.
• CoreOne and CORE One L owners seeking reliable, long-lasting nozzles for high-speed printing.
• Prusa MK3.9 and MK3.9S users replacing stock nozzles with a premium, wear-resistant option.
• Enthusiasts printing carbon fiber, wood-fill, or glow-in-the-dark filaments on Prusa Nextruder systems.
• Users requiring quick, toolless nozzle changes to maximize printer uptime.

Pair With the Right Filament

Maximize the durability and print quality of your Prusa Nextruder by pairing this nozzle with abrasive and specialty filaments designed for high-performance printing.

• Carbon Fiber Filament — ideal for functional parts requiring strength and wear resistance.
• ABS Filament — compatible with high-temperature printing and durable applications.
• Nylon Filament — perfect for flexible, strong parts that benefit from the nozzle's abrasion resistance.
