At the same 0.4 mm opening, compare brass for an ordinary filament profile with a coated option where your filament supplier calls for wear resistance.
Fit guide
Choose a Prusa Nextruder nozzle or a V6 adapter
If you already own suitable V6 nozzles, check whether Prusa’s adapter supports your specific printer. If you want a direct replacement for a Nextruder, begin with the native Prusa Nozzle family and compare the size, material, and printer profile you plan to use.
What to check
- Identify the printer and the hotend on it. Then use the model-specific installation instructions for the adapter if one is required.
- Match the nozzle to the appropriate printer and diameter profile in PrusaSlicer. If the diameter lacks a preset, follow Prusa’s guidance to create a profile before switching.
- For coated nozzles, follow the manufacturer’s cleaning instructions for that exact surface. Prusa specifies different treatment for its ObXidian coating.
Compare products
Compare 0.4 and 0.6 mm openings on the same Nextruder format when a filled filament specifies a minimum opening.
Questions about this choice
Can I use my E3D V6 nozzles on a supported Nextruder printer?
Prusa documents a Nextruder V6 adapter for several models, including MK4, MK4S, and XL. Confirm your printer on the compatibility list and use the matching installation instructions.
Should I select a high-flow profile after replacing the nozzle?
Use a high-flow profile only when it matches the nozzle and printer setup you are installing. For Prusa’s high-flow variants, use the documentation for the exact nozzle to choose the slicer profile.
