Product features

• Extreme wear resistance – The ObXidian® nozzle allows you to print even the most abrasive filaments, such as carbon fiber and glass fiber, without any issues.

• Up to 70% higher flow – Thanks to High Flow nozzle technology, the volumetric flow can be up to 70% higher than the standard Bambu Lab hotend, allowing for higher print speeds without sacrificing quality.

• Prevents plastic buildup – The innovative E3DLC™ anti-stick coating prevents filament from accumulating around the nozzle and makes cleaning the hotend significantly easier.

• Longer service life – The ObXidian® coating makes the nozzle much harder than traditional steel nozzles, significantly reducing wear and greatly extending its lifespan.

• Easy installation – A drop-in upgrade for your existing hotend. No printer modifications or additional hardware required.

⚠️ Note: Only compatible with Bambu Lab A1 and Bambu Lab A1 Mini.

Key features

High Flow technology

Due to an internal modification of the nozzle, this hotend can handle a up to 70% higher volumetric flow. This allows you to print faster while keeping extrusion stable and consistent.

Tip: Increase the Volumetric Flow Limit in your slicer to make the most of this upgrade.

Suitable for abrasive filaments

Thanks to the durable ObXidian™ nozzle, this hotend is ideal for printing with wear-prone materials such as:

• Carbon fiber filament

• Glass fiber filament

• Glow-in-the-dark filament

• Metal-filled filaments

Consistent print quality at high speed

Even at higher print speeds, print quality remains maintained. The improved heat transfer ensures:

• Strong layer adhesion

• Accurate details

• Smooth surfaces

As a result, prints remain strong, reliable, and suitable for functional applications.

Slicer settings

To utilize maximum performance, you can increase the Volumetric Flow Rate in your slicer. This allows the printer to benefit from the improved heat transfer and higher filament throughput.

Plug & Play installation (Drop-in upgrade)

This magnetic hotend is designed as a direct replacement for the standard hotend.

Installation is simple:

1. Remove the existing hotend

2. Click the new ObXidian HotEnd into place

3. Ready to print

The heater and temperature sensor are already integrated into the toolhead, meaning no adjustments to mounts or cooling are necessary.

Frequently asked questions

Will this product shorten my print time?

In many cases, yes. Thanks to the higher volumetric flow, you can print faster. The actual time saved depends on the model, slicer settings, and print speed.

Does the nozzle wear out over time?

Yes, every nozzle can eventually wear out. However, thanks to the ObXidian® technology, this happens significantly slower than with standard hardened steel nozzles.

Will I lose my printer warranty?

No. These HotEnds are officially approved by Bambu Lab and do not affect the printer's warranty.

Can I also use normal filaments like PLA?

Yes. Even with standard filaments, you will benefit from better heat transfer, more stable extrusion, and better-looking prints.
