Supercharge your Prusa 3D printer with the E3D High-Flow ObXidian Nozzle. Specifically engineered for Prusa's advanced Nextruder system, this premium aftermarket upgrade is the ultimate solution for makers and professionals looking to unlock maximum volumetric flow rates without sacrificing wear resistance.
Compatible with the Prusa MK4, MK4S, XL, and CoreOne, this nozzle features an integrated all-metal filament guide. This ensures a 100% metal filament path throughout the Nextruder, improving overall thermal efficiency and enabling lightning-fast nozzle swaps.
🚀 High-Flow Performance, No Setup Changes
Unlike traditional high-flow setups (like Volcano or SuperVolcano) which require bulky extensions, the E3D High-Flow ObXidian Nozzle maintains the exact same physical form factor as standard Nextruder nozzles.
-
Drop-In Compatibility: No need to modify your pre-existing mounting bracket, print cooling fan ducts, or software height offsets.
-
Internal Geometry: Uses a unique, custom internal geometry designed to maximize surface area contact, delivering vastly superior heat transfer to melt filament faster.
💎 Legendary ObXidian™ Wear Resistance
Abrasive carbon fiber, glass fiber, and metal-filled filaments quickly destroy standard brass nozzles. ObXidian is built to last.
-
Hardened Tool Steel: Features a rugged tool steel insert coated with E3D’s proprietary E3DLC™ (carbon-like) coating for wear resistance orders of magnitude higher than standard hardened nozzles.
-
Non-Stick Properties: The specially formulated coating prevents sticky, molten plastic from building up on the outside of the nozzle, keeping your toolhead clean.
-
Easy Identification: Each nozzle size is permanently engraved directly onto the nozzle body so you never have to guess.

⚠️ Wear Note: While ObXidian is exceptionally wear-resistant, extremely aggressive filled engineering filaments (such as Polymaker's PolyMide PA6-CF/GF, PA12-CF, or PA612-CF) can still cause wear over prolonged periods of heavy use.
⚠️ California Proposition 65 Warning: This product can expose you to chemicals including Mineral Oils, which is known to the State of California to cause cancer, and Lead and Nickel, which are known to the State of California to cause cancer and birth defects or other reproductive harm.
