E3D High Flow ObXidian® 500 HotEnd for Bambu Lab H2 Series
Unlock the full speed potential of your Bambu Lab H2 printer with the E3D High Flow ObXidian® 500 HotEnd. Powered by next-generation ObXidian 500 technology, this drop-in upgrade delivers dramatically higher flow rates, extended nozzle life, and cleaner extrusion so you can print faster with demanding, abrasive filaments while maintaining reliable, high-quality results.
Why Upgrade to ObXidian 500 High Flow?
- Massive flow boost: Unique 4-channel internal nozzle geometry improves heat transfer into the filament, enabling over 60% higher volumetric flow compared to standard hardened hotends (material and settings dependent).
- Extreme wear resistance: Advanced coating and hardened construction make the nozzle at least 5x more wear-resistant than the original ObXidian, greatly extending service life in abrasive applications.
- Print almost any filament: Confidently run carbon fibre, glass fibre, metal-filled and glow-in-the-dark materials without rapidly wearing out your nozzle.
- Non-stick nozzle surface: Special low-adhesion finish helps prevent plastic build-up around the tip, reducing print defects and the risk of head crashes.
- High-temperature capable: Rated up to 500 °C, opening the door to more advanced engineering polymers when paired with a suitable printer and enclosure.
- Official Bambu Lab collaboration: Designed and approved in partnership with Bambu Lab as a direct, drop-in performance upgrade for the H2 platform.
