These premium HotEnds are an official collaboration between E3D, DiamondBack, and Bambu Lab - bringing you the most extreme HotEnd solution to date. E3D are very proud to be the only officially approved manufacturer of aftermarket Bambu Lab HotEnds.

Why Choose Diamond?

The rapid development of fibre, metal and ceramic filaments has increased the need for abrasion-resistant nozzles. Compared with all the nozzle options on the market, DiamondBack’s diamonds deliver unmatched wear-resistance and versatility.

Smooth and Hard. Unlock extreme wear resistance on your Bambu Lab printer thanks to DiamondBack’s Polycrystalline Diamond (PCD) tips. These diamonds are composed of thousands of tiny diamond crystals with a proprietary binder that forms a matrix of crystals joined with diamond-to-diamond bonds. They retain the hardness properties of diamond whilst reducing the inherent brittleness of a single-crystal diamond, making them a fantastic choice for printing with engineering grade metal and ceramic-filled filaments.

Precision Printing. DiamondBack nozzles rely on a solid diamond tip to improve precision 3D printing. The tip is not a diamond coating, but rather a solid diamond insert made from the hardest material in the world.

Longevity. The PCD used in these Bambu Lab HotEnds significantly extends nozzle life. It provides best-in-class thermal conductivity which improves interlayer adhesion for stronger prints, and the low coefficient of friction combined with a polished tip creates super smooth top layers with an ironing-like effect.

Effortless Upgrade. These HotEnds are a drop-in replacement for your stock Bambu Lab Hotend, no adjustment to the mount or part cooling is required. Maintain your stock Bambu Lab print profiles as they’re a perfect match.

Compatibility. These kits come in multiple variants with matching connectors for Bambu Lab's different printer models.

E3D are very proud to be the only officially approved manufacturer of aftermarket Bambu Lab HotEnds! These ObXidian High Flow HotEnds were developed in collaboration with Bambu Lab, bringing you one of the most compact, lightweight and, more importantly, performant HotEnds to date.

High Flow. There's no denying that the Bambu Lab X1 and P1 series printers are built for speed. However, the motion system, as remarkable as it is, has headroom to be even better. That's where E3D High Flow technology comes in. Using our internal nozzle modification, we've managed to increase the volumetric flow rate of the HotEnd by 60%! That means you can expect more reliable and consistent extrusion at the same speeds or bump up the volumetric flow rate limit in the slicer to utilise the motion systems' capabilities fully.

Smooth and Hard. We've applied our E3DLC™ coating to the nozzle and heater parts, adding even more abrasive resistance for all your fibre-filled fun and a non-stick protective layer to prevent plastic build-up on the Nozzle.

Improved Layer Adhesion. High speed printing often sacrifices visual and functional aspects in favour of speed but these Hotends maintain interlayer adhesion strength even at higher speeds; resulting in the correct filament finish and strong parts for functional applications.

No Compromise. All of these new additions come in the same form factor as your stock Bambu. Simply drop-in place with no adjustment to the mount or part cooling required. Complete the upgrade in under 5 mins with our installation video guide.

Compatibility. These kits come in two different variants with matching connectors for the X1 series and P1 series printers

These high-quality 3D printing nozzles are designed specifically for use with Prusa’s latest extruder – Nextruder. Compatible with Prusa’s MK4, MK4S 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.

Higher Flow. E3D Prusa High Flow ObXidian Nozzles increase your setup's volumetric flow rate, enabling you to print faster!

How does this work? E3D Prusa High Flow ObXidian Nozzles maintain the exact same form factor as standard E3D Prusa ObXidian Nozzles; this means there is no need to adjust your pre-existing mount and fan duct setups! E3D Prusa High Flow Brass Nozzles use a unique custom internal geometry to increase the surface area for improved thermal transfer to the filament.

With a wear resistance orders of magnitude higher than any other E3D nozzle, ObXidian is really hard, making it the perfect nozzle for printing abrasive/filled polymers. This is achieved by pairing a tool steel insert with our new E3DLC™ coating. This specially formulated coating also embeds non-stick properties into the Nozzle itself, meaning 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. Each Nozzle has its size engraved into it.
