Product description: 0.4 mm E3D Prusa Nozzle High Flow ObXidian for Nextruder - 1.75 mm filament - tool steel + E3DLC
The E3D Prusa High Flow ObXidian Nozzle in its 0.4mm diameter is a high-quality nozzle compatible with the Nextruder system used in modern Prusa printers , such as the MK4, MK3.9, and XL. Thanks to its unique internal high-flow geometry, it allows for significantly higher filament flow rates , resulting in faster printing without compromising quality. Additionally, the all-metal construction without PTFE tubing increases reliability and simplifies maintenance.
0.4mm E3D Prusa Nozzle High Flow ObXidian for Nextruder - 1.75mm filament - tool steel + E3DLC. 
The nozzle is compatible with the Nextruder system.Main features of the nozzle
- High-flow E3D : increased contact surface for efficient heat transfer and higher flow
- Extreme abrasion resistance : ideal for materials with carbon or mineral fibers
- E3DLC coating : anti-stick properties - less residue and cleaner prints
- No modifications required : fully compatible with Prusa heatsink holder and cooling channels
- Quick replacement : intuitive, quick installation in printers with Nextruder
- Convenient identification : engraved size makes it easy to distinguish the nozzle
Practical applications
The ObXidian nozzle is ideal for rapid technical printing and the production of functional prototypes using abrasive filaments such as PETG Tungsten, PC Blend Fiber, or other materials with fiber additives. It ensures uniform extrusion even at high printing speeds, significantly reducing project completion times. Recommended for advanced users and professionals.
