Prusa Nextruder E3D Nozzle: High Flow ObXiDian 500 - 0.4mm

E3D's new ObXiDian 500 coating on a High Flow Nextruder nozzle: at least five times the wear resistance of ObXidian, non-stick, and a straight swap on any Nextruder printer.

Overview

Genuine E3D nozzle developed with Prusa for the Nextruder and sold as an official Prusa part. It pairs E3D's four-channel High Flow insert, which pushes more heat into the filament so you can run a higher volumetric flow limit or get steadier extrusion at your current speeds, with the new ObXiDian 500 coating. E3D rates that coating at least five times more wear resistant than its ObXidian range and several orders of magnitude tougher than ordinary hardened steel at the primary wear points, so carbon fibre, glass fibre, glow in the dark and other filled filaments stop chewing through nozzles. The same low surface energy coating resists plastic build-up, which keeps the nozzle cleaner between prints and cuts down on print crashes and cosmetic blemishes. It keeps the standard Prusa Nextruder nozzle form factor, so it fits the existing mount and fan ducts with no hardware changes. The nozzle itself is rated by E3D to 500°C, well beyond what a Nextruder hotend will ask of it, so your printer's own temperature limit is the ceiling.

Key Details

Features

• Four-channel High Flow insert for a higher volumetric flow limit, or more consistent extrusion at the same speeds
• ObXiDian 500 coating, at least five times more wear resistant than E3D's ObXidian
• Prints abrasive filaments: carbon fibre, glass fibre, glow in the dark and other filled materials
• Non-stick coating with low surface energy, so plastic build-up, print crashes and cosmetic defects drop away
• Holds interlayer adhesion at high speed for a clean finish and strong functional parts
• Standard Nextruder nozzle form factor, straight swap with no hardware modifications
• Official E3D and Prusa collaboration, does not void the Prusa warranty

Compatibility

Listed by Prusa as compatible with every Nextruder printer: MK4, MK4S, MK3.9, MK3.9S, XL, XL+, CORE One/+, CORE One+ (Gen 2), CORE One L and CORE One L+. Prusa lists it as not compatible with the MK3S+, MK3.5, MK3.5S, MINI and MINI+ (different nozzle system), the Prusa Pro HT90 (Revo nozzles), or the INDX tool heads for the CORE One and CORE One L, which take their own Bondtech nozzles. Install it following the nozzle change guide for your printer on the Prusa Knowledge Base.

Please note: E3D advises that some newer engineering filaments with aggressive fillers, Polymaker's Fiberon range among them, can still wear an ObXiDian 500 nozzle. Filled materials with particles close to or larger than 0.4mm also raise the risk of jams through a 0.4mm bore, so check the filament maker's datasheet for its minimum recommended nozzle size.
