E3D High Flow ObXiDian® 500 HotEnd – Bambu Lab H2D / H2S / H2C / P2S

The E3D High Flow ObXiDian® 500 HotEnd is a premium upgrade for Bambu Lab 3D printers, developed in an official partnership between E3D and Bambu Lab. Thanks to its innovative ObXiDian® 500 coating, this HotEnd offers exceptional wear resistance and a significantly higher filament throughput for fast and reliable 3D prints.

The unique 4-channel High Flow nozzle technology increases the volumetric flow by more than 60%, allowing you to achieve higher print speeds without losing print quality. Furthermore, the special coating makes the nozzle extremely wear-resistant, enabling even abrasive filaments such as glow-in-the-dark or fiber-reinforced materials to be printed without issues.

Thanks to Bambu Lab's smart magnetic HotEnd system, this upgrade can be installed in seconds with no modifications to the printer required.

Key features

More than 60% higher flow rate
The unique 4-channel internal nozzle design improves heat transfer to the filament and significantly increases the volumetric flow.

New ObXiDian® 500 technology
The advanced coating makes the nozzle at least 5× more wear-resistant than standard ObXidian nozzles and significantly more durable than hardened steel.

Suitable for all filaments
Print seamlessly with standard and abrasive materials such as carbon fiber, glass fiber, and glow-in-the-dark filament.

Anti-stick coating
The low surface energy of the coating prevents plastic from building up around the nozzle, which reduces print errors and nozzle clogging.

Fast and easy installation
Thanks to the magnetic design, the HotEnd can be easily replaced without tools or hardware adjustments.

Officially approved by Bambu Lab
E3D is the only aftermarket HotEnd manufacturer officially approved by Bambu Lab.

Important information

ObXiDian® 500 nozzles are extremely wear-resistant and last significantly longer than standard nozzles. Nevertheless, highly abrasive engineering filaments, such as some carbon and glass fiber materials, may cause wear over time. Always check the filament manufacturer's recommended nozzle diameter to prevent clogging.

Frequently asked questions

Will this product reduce 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® 500 coating, this happens much more slowly 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, absolutely. Even with standard filaments, you benefit from better heat transfer, more stable extrusion, and higher quality prints.
