These nozzles are particularly suitable for printing with abrasive materials like carbon fiber, as they maintain their hardness even at higher temperatures, delivering excellent performance and extending the lifespan of your nozzle.

Includes: Nozzle (1 pcs)

Fits:
Prusa CORE One
Prusa MK3.9
Prusa MK3.9S
Prusa MK4

To replace this part, please consult the Prusa Assembly Manuals. Make sure to follow the manual for your printer model.

 Important 
1) These are not the CHT nozzles that come stock on the MK4S printers.
2) You may need to adjust your Z offset when changing nozzles.
3) ObXidian™ coated nozzles are exceptionally wear resistant. However, improvements in ‘exotic’ engineering filaments mean that some new materials which include aggressive fillers, including but not limited to Polymaker’s PolyMide and Fiberon range (PA612-CF, PA6-CF, PA6-GF, PA12-CF etc), can cause significant wear on even ObXidian nozzles. E3D is actively developing even more specialist solutions for these materials. In the meantime, E3D states: "please be aware that even the rainbows and unicorns in your ObXidian nozzle are not everlasting under extreme material conditions." :)
4) Some filled materials contain particles that are close to, if not larger than, some of the smaller industry standard nozzle sizes, including up to 0.4mm. Attempting to print such materials through these nozzle sizes significantly increases the risk a jam. Please check your filament manufacturer’s datasheet for recommended minimum nozzle orifice diameter to ensure that the nozzle/hotend you choose is suitable for your use case.
