E3D ObXidian™ High Flow HotEnd for Bambu Lab A1 / A1 Mini

The High Flow ObXidian™ HotEnd is a premium upgrade developed in collaboration between E3D and Bambu Lab. It is engineered for durability, high-speed reliability, and easy assembly, so you can confidently print even the most abrasive filaments. With up to 70% higher flow than Bambu Lab's standard HotEnd, it delivers stronger parts, smoother surfaces, and faster prints without compromising quality. Available in 0.4mm and 0.6mm.

Important features

• Up to 70% higher flow than standard HotEnd
• Outstanding wear resistance with E3DLC™ coating
• Prevents plastic buildup for cleaner prints
• Maintains strength and finish even at high speed
• Easy drop-in installation without modifications
• Officially approved by Bambu Lab

Designed for speed and reliability

Thanks to its redesigned internal geometry, the High Flow ObXidian™ HotEnd increases volumetric flow rate by up to 70%. This means more consistent extrusion and the freedom to increase print speed while maintaining quality and reliability.

Built to last

The ObXidian™ nozzle features E3D’s advanced E3DLC™ coating, making it orders of magnitude harder than conventional steel nozzles. This ensures exceptional durability, even when printing with abrasive filaments like carbon fiber or fiberglass-filled materials. No nozzle lasts forever under extreme use, but ObXidian significantly extends the lifespan compared to hardened steel.

Cleaner prints, less maintenance

The non-stick coating reduces plastic build-up on the nozzle and minimizes the risk of print failures and cosmetic defects. Less cleaning means you can focus more on printing.

Easy to upgrade

Installation is quick and tool-free thanks to the magnetic design. Simply remove your existing HotEnd, insert the new one, and you're good to go. No hardware changes or adjustments are required.
