The High Flow ObXidian hotend from E3D redefines the performance of Bambu Lab 3D printers with a revolutionary improvement in extrusion flow and print quality. Designed by E3D in collaboration with Bambu Lab, this high-flow hotend provides a faster, more precise, and durable printing experience thanks to its advanced High Flow technology and exclusive E3DLC coating.

This fully assembled hotend is specifically designed for the Bambu Lab X1, X1 Carbon, P1S, and P1P series, ensuring a direct installation without additional modifications or adjustments. Its plug & play system allows replacing the original hotend in minutes, without broken cables or thermal paste leaks, offering an immediate and reliable extrusion system upgrade.

High Flow Performance for Unstoppable Extrusion

Thanks to its innovative internal design, the High Flow ObXidian increases volumetric flow by 60% more than the standard Bambu Lab hotend, allowing for consistent extrusion even at high speeds. This performance boost results in faster prints, uniform layers, and parts with greater structural strength, fully utilizing the printer's motion system potential.

The High Flow technology removes traditional speed limits, improves layer adhesion, and delivers professional results for functional parts, industrial prototypes, and high-precision models. Adjusting the volumetric flow in the slicer allows reaching maximum performance without compromising final quality.

E3DLC Coating: Superior Durability and Cleanliness

The E3DLC coating applied to the nozzle and heater block provides exceptional abrasion resistance, especially useful when printing with technical filaments reinforced with carbon, glass, or metal fibers. This non-stick coating prevents filament residue buildup, keeps the nozzle cleaner for longer, and extends the hotend’s lifespan.

Additionally, the hardened composition of the ObXidian nozzle ensures stable performance even in extreme conditions, reaching temperatures up to 300°C without loss of precision or material degradation.

Quick Installation and Full Compatibility

The High Flow ObXidian HotEnd kit includes all necessary components for a direct replacement: fan, temperature sensor, heating element, mounting clip, silicone sock, and installation materials. It maintains the same form factor as the original systems, so no PID adjustments or cooling system modifications are required.

Its compatibility with Bambu Lab X1, X1 Carbon, P1S, and P1P makes it the ideal choice for those seeking speed, reliability, and professional extrusion quality in every 3D print.

Innovation Without Compromise

The High Flow ObXidian combines advanced engineering with ease of use. Every detail is designed to maximize performance without sacrificing stability. Its compact and lightweight structure allows for higher printing speeds without losing precision or consistency, transforming any Bambu Lab 3D printer into a high-performance machine.

Compatibility

The High Flow ObXidian HotEnds are not compatible with the Bambu X1E printer. Although they can be physically installed, the maximum working temperature is limited to 300 °C, which may restrict their performance with certain technical materials.

Maximum printing temperature

The maximum printing temperature is 300 °C. It is not recommended to exceed this limit to avoid damage to the ObXidian™ coating or the internal components of the HotEnd.

Recommended filaments and materials

These HotEnds are compatible with all filaments that work with E3D Revo and V6 ObXidian nozzles. They are especially designed for fiber-reinforced filaments (for example, carbon fiber or glass fiber), as well as filaments with glitter or glow-in-the-dark particles.

They can also be used with metal- or ceramic-filled filaments, although this is recommended only occasionally, as these materials cause wear during prolonged use.

Wear resistance

ObXidian™ nozzles offer significantly higher wear resistance than conventional hardened nozzles. However, some advanced engineering materials with highly abrasive fillers—such as the Polymaker Fiberon range (PA612-CF, PA6-CF, PA6-GF, and PA12-CF)—may still wear down the nozzle over time.

If you frequently work with such materials, it is advisable to consider more specialized solutions; E3D is developing specific options for extreme use cases.

Nozzle size and clogging risk

Some filled filaments contain particles of a size similar to or larger than 0.4 mm. Printing these materials with small nozzles significantly increases the risk of clogs. Always check the filament’s technical data sheet and ensure you are using a suitable nozzle diameter for the material.

Cleaning and maintenance

The HotEnd supports the “cold pull” technique. The ObXidian™ coating is designed to withstand the force of this method, although the process may be slightly more demanding than with conventional nozzles due to the internal structure of the HotEnd.

Calibration (PID)

It is not necessary to perform PID tuning after installing the E3D ObXidian High Flow HotEnd on the Bambu printer.

Compatibility with Revo nozzles

These HotEnds maintain the same external shape as the original Bambu nozzles and are therefore not compatible with the E3D Revo nozzle range. If you need compatibility with the Revo system, consider the Revo Panda by Biqu model, specifically designed for that purpose.

Final recommendation: if you frequently process highly abrasive filaments, plan periodic nozzle inspections and keep specialized spare nozzles on hand to minimize downtime.
