E3D High Flow ObXiDian 500 H2/P2 Hotend 0.4 mm

This premium hotend combines high flow rates, exceptional durability and broad compatibility with filaments in one drop-in upgrade.
Developed in collaboration between E3D and Bambu Lab, it delivers significantly improved print performance for the H2 and P2 series machines from everyday PLA prints to demanding composites. Whether you’re looking for faster printing or reliable extrusion with abrasive filaments, this Hotend gives you both.

Key advantages

• Up to 60% higher volumetric flow
• At least 5× more wear resistant than standard hardened nozzles
• Works with standard, abrasive and specialised files
• Non-stick nozzle that reduces plastic build-up and the risk of failed printing
• Retains strong adhesion between layers even at high speeds
• Easy magnetic “drop-in” installation without the need for hardware changes

Choose a higher flow rate

The innovative 4-channel internal nozzle of this hotend significantly improves the heat transfer in the filament
and allows an increase in volumetric flow rate of over 60%.
This means more reliable and uniform extrusion at the same speeds
or the ability to raise the volumetric flow limit in the slicer,
to use the full potential of the machine’s kinematics.

High quality at high speed

High speed printing often compromises on appearance and strength,
but these hotends retain excellent adhesion between layers even at higher speeds.
The result is a perfect filament finish and robust details,
suitable for functional applications.

Unlock the seal with “stiff” filaments

Most abrasive materials simply cannot wear out an ObXiDian 500 nozzle.
With this upgrade, you can print with whatever filament you want
(including UV-reactive and “glow in the dark” filaments),
without constant maintenance and nozzle changes.

Long life nozzles

The ObXiDian 500 technology significantly extends nozzle life,
making key wear areas several orders of magnitude more resistant
than other steel nozzles on the market.
Better for your budget and better for the planet.

End of gluing

Modern nozzle coating has low surface energy,
which prevents filament build-up.
This facilitates cleaning between prints and significantly reduces
the risk of failed stamps and cosmetic defects.

Effortless – easy upgrade

These magnetic hotends are extremely easy to install.
The heater and temperature cables are built into the toolhead,
so you just need to unplug the old hotend,
plug in the new one and you’re done.
No mechanical adjustments or changes to cooling are required.

Frequently Asked Questions

Will this product reduce printing time?

The reduction in print time depends on many factors,
including the specific model you are printing.
In most cases, when using our pre-prepared
slicer profiles, you will notice shorter print times.
However, if you are printing very small and detailed models with minimal or no infill,
you may not see a dramatic reduction in time,
as the priority is to maintain high visual quality
of the outer contours.

Will the nozzle wear out over time?

Yes, with long enough use the nozzle may show signs of wear,
but this will happen significantly slower than a standard
hardened steel nozzle.
The expected life of the product is difficult to determine accurately,
as it depends on many variables – base polymer,
additives, filament brand, temperature and print speed.

Does this void my printer warranty?

No. Bambu Lab have worked with E3D on the development of
and have officially approved the use of this product.

Can I still print with standard filaments like PLA?

Of course! Even when using standard print profiles
you will notice a more consistent and uniform visual quality,
thanks to the improved thermal performance and increased flow
of the high flow variants. This results in stronger and better looking details.

What is the use of this product if my printer does not reach 500°C?

You are always limited by the maximum print temperature of the
machine itself (for H2D / H2C / H2S printers it is 350°C).
However, even when printing at lower temperatures,
you will benefit from all the other advantages of the product –
extremely high abrasion resistance that significantly extends nozzle life,
as well as a non-stick coating that facilitates cleaning
and reduces plastic build-up and print defects.
