Genuine Original Prusa XL / MK4 / CoreOne Obxidian Abrasive Resistant Nozzles by E3D

  These high-quality hardened 3D printing nozzles are designed specifically for use with Prusa’s latest extruder – Nextruder. Compatible with Prusa’s MK4 and XL 3D printers, they feature an all-metal filament guide which means that Nextruder’s filament path is entirely metal. This helps improve overall printer reliability and enables speedier nozzle changing.   With a wear resistance that is orders of magnitude higher than any other E3D nozzle, ObXidian is really hard, making it the perfect nozzle for printing abrasive/filled polymers with. This is achieved by pairing a tool steel insert with our E3DLC™ coating. This specially formulated coating also embeds non-stick properties into the Nozzle itself, resulting in considerably less plastic build-up around the Nozzle.  Simplified nozzle changing. Changing a nozzle on your Prusa printer just got much easier! Waste less time changing your nozzles and more time experimenting with different sizes and materials.    Easy identification. Eac
