E3D High Flow ObXidian Hot End for Bambu Lab Printers X1 and P1 Series (X1C P1P etc.) - Fully Assembled and Self Assembled Kits

E3D ObXidian High Flow HotEnd for Bambu Lab X1, X1C, P1S & P1P

The E3D ObXidian High Flow HotEnd is an official collaboration between E3D and Bambu Lab — a drop-in replacement hotend that delivers 60% more volumetric flow than the stock Bambu hotend, without changing the form factor, mount, or part cooling setup. Same footprint. Significantly more performance.

60% More Volumetric Flow

Bambu Lab's X1 and P1 series motion systems are built for speed — but the stock hotend is often the bottleneck. E3D's internal nozzle modification increases volumetric flow rate by 60%, letting you either push higher speeds without under-extrusion, or raise the volumetric flow limit in your slicer to finally use the full capability of the motion system.

E3DLC™ Diamond-Like Coating

Every ObXidian HotEnd features E3D's proprietary E3DLC™ coating applied to the nozzle and heater components. This diamond-like carbon coating adds exceptional abrasive resistance for fiber-filled filaments and creates a non-stick surface that prevents plastic buildup on the nozzle — keeping flow consistent across long print sessions.

True Drop-In Replacement

The ObXidian High Flow maintains the exact same form factor as the stock Bambu hotend. Reuse your existing temperature sensor and heater pads — no adjustment to the mount, no changes to part cooling, no PID tuning required. Just swap and print.

Specifications

What's in the Box

• 1× E3D ObXidian High Flow HotEnd (0.40mm or 0.60mm — select your size)
• 1× Thermal Grease
• 1× Bambu Lab Sock
• 1× Bambu Lab Heater Retaining Spring
• 2× Bambu Lab Bolts

Compatible Filaments

The ObXidian coating is optimized for abrasive materials including carbon fiber, glass fiber, glow-in-the-dark, and glitter-filled filaments. Short-run metal and ceramic-filled filaments can be used, though prolonged use with these may cause gradual wear. For standard PLA, PETG, ABS, TPU, and ASA, this hotend is simply overkill — in the best way.

FAQ

What is the maximum printing temperature?
300 °C.

Can I cold pull the ObXidian High Flow HotEnd?
Yes. The E3DLC coating withstands the force of a cold pull, though it can be slightly more challenging than a standard nozzle due to the internal construction.

Are there material limitations?
Any filament compatible with E3D Revo or V6 ObXidian nozzles works here. It's optimized for fiber-filled, glow-in-the-dark, and glitter filaments. Short periods with metal or ceramic-filled filaments are fine, but prolonged use may still cause wear.

Do I need to PID tune after installing?
No PID tuning required.

Is this compatible with E3D Revo nozzles?
No — the ObXidian High Flow uses the stock Bambu nozzle format to maintain drop-in compatibility. If you want Revo nozzle compatibility on a Bambu printer, look into the Revo Panda by BIQU instead.
