E3D High Flow ObXidian™ Hotend — Bambu Lab P1 Series
This is the official E3D and Bambu Lab collaboration hotend, built specifically for the P1P and P1S. Inside the familiar Bambu form factor is E3D's high-flow melt zone, which raises volumetric flow by around 60% over the stock Bambu hotend, topped with an ObXidian hardened nozzle finished in E3D's E3DLC coating for non-stick, abrasion-resistant printing. It drops straight into the toolhead — no mounting changes, no cooling modifications, no firmware fiddling.
The practical upshot: faster prints without pushing your extruder into under-extrusion, and a nozzle that survives the filaments that destroy brass — glow-in-the-dark, glitter and sparkle PLA, wood- and metal-filled blends, and carbon- or glass-reinforced composites.

Which configuration is right for you?
There are two decisions to make: how much of the assembly you want (Complete Hotend vs Hotend) and which nozzle size (0.4 mm vs 0.6 mm). The hotend itself is identical across all four — the flow performance and the ObXidian tip don't change.
| Option |
You get |
Choose it if… |
| Complete Hotend |
Pre-assembled with the P1 hotend cooling fan, heating element and temperature sensor fitted, plus sock, retaining clip and bolts |
You want the quickest, lowest-risk swap, your old heater or fan is tired, or you'd rather keep the original hotend intact as a spare |
| Hotend (metal only) |
The hotend alone, with thermal grease, silicone sock, heater retaining spring and 2× bolts — you transfer your existing heater, thermistor and fan across |
Your current electronics are in good health and you're comfortable spending 15–20 minutes inside the toolhead |
| 0.4 mm nozzle |
29 mm³/s PLA · 32 mm³/s PETG · 35 mm³/s ASA · 33 mm³/s PC |
General-purpose printing — miniatures, detailed models, enclosures. Your existing 0.4 mm profiles carry straight over |
| 0.6 mm nozzle |
36 mm³/s PLA · 42 mm³/s PETG · 34 mm³/s ASA |
Functional parts, big props, jigs and composite filaments — thicker layers, stronger walls, far shorter print times |
Still unsure? Most P1 owners upgrading for the first time take the Complete Hotend / 0.4 mm — easiest install, no profile rework. Workshops and small businesses printing production parts tend to buy a 0.6 mm and keep a 0.4 mm on the shelf for detail jobs.

What's in the box
-
Complete Hotend: pre-assembled ObXidian hotend with P1-series cooling fan, heating element and temperature sensor fitted, plus silicone sock, hotend retaining clip and 2× mounting bolts
-
Hotend (metal only): ObXidian hotend, thermal grease, Bambu Lab silicone sock, heater retaining spring and 2× bolts — reuse your existing heater, thermistor and fan
Who it's for
-
Makers and hobbyists who've hit the flow ceiling of the stock hotend and want speed without a new printer
-
Small businesses and print farms running batch jobs where hours saved per print compound quickly
-
Anyone printing abrasives — sparkle and glow PLA, wood- and metal-filled blends, CF/GF composites (note that very aggressive carbon- and glass-filled nylons will still wear the tip faster than plain filaments)
-
Schools and workshops replacing a worn or clogged hotend and upgrading performance in the same swap
Good to know before you buy
- This listing is for the P1 Series only — fitting a P1-series assembly to an X1C requires the X1C version instead
- Run a flow-rate and pressure-advance calibration after installing, and set the new nozzle size in Bambu Studio or Handy
- Let the hotend cool completely and power the printer off before swapping anything

Dispatched from our Australian warehouse with tracking to every state and territory, and all prices include GST with a tax invoice supplied. This is an internal printer part — there's no mains plug or AU power adapter involved, it runs from your P1's own 240 V AC supply. Not sure which configuration suits your machine or your filaments? Message us before you order and we'll point you to the right one.
Complete Hotend — 0.4 mm (P1P / P1S)
The easiest way to fit the E3D × Bambu Lab High Flow ObXidian to a P1P or P1S. Everything arrives pre-assembled: the high-flow melt zone and 0.4 mm hardened ObXidian nozzle come already paired with the P1-series hotend cooling fan, heating element and temperature sensor. Unplug the old hotend assembly, plug this one in, calibrate, print — no thermal paste, no loose electronics, no mounting or cooling modifications.
0.4 mm is the configuration most P1 owners should choose. You keep the detail and wall quality your existing profiles are tuned around, while moving roughly 60% more material per second than the stock Bambu hotend — that's where the time savings on big, infill-heavy prints come from. The ObXidian tip with E3DLC coating shrugs off glow, glitter and fibre-filled filaments that quickly ruin plain brass.

Complete Hotend — 0.6 mm (P1P / P1S)
If your P1 earns its keep on functional parts, cosplay shells, jigs or batches of brackets, this is the configuration that pays back fastest. The 0.6 mm ObXidian nozzle lays a wider extrusion and the high-flow melt zone keeps up with it: 36 mm³/s in PLA and 42 mm³/s in PETG, roughly 60% more than the stock Bambu hotend. Fewer perimeters, thicker layers, noticeably shorter prints, stronger walls as a bonus.
It arrives fully built — hotend cooling fan, heating element and temperature sensor already fitted — so installation is a swap-and-plug job with no thermal paste and nothing to transfer. The hardened ObXidian tip with E3DLC coating handles glow, glitter, wood-filled and fibre-reinforced filaments far better than brass, though very aggressive carbon- and glass-filled polyamides will still shorten its life.

Hotend (metal only) — 0.4 mm (P1P / P1S)
Mechanically this is the identical ObXidian high-flow hotend as the complete assembly: the same enlarged melt zone, the same roughly 60% jump in volumetric flow over the stock Bambu hotend, the same 0.4 mm hardened ObXidian tip with E3DLC coating. The difference is what's attached to it — this version ships as the metal hotend alone, so you transfer the heating element, temperature sensor and hotend cooling fan from the hotend currently in your P1.
It's the sensible pick when your existing electronics are healthy and you simply want the flow and the hardened nozzle. Budget 15–20 minutes: remove the old assembly, move the heater and thermistor across using the supplied thermal grease, clip the fan over, fit the sock and the two bolts, then run a flow and pressure-advance calibration. If your fan is noisy or the heater has already been through a few swaps, take the Complete Hotend instead.

Hotend (metal only) — 0.6 mm (P1P / P1S)
The highest-throughput, lowest-outlay way to upgrade a P1P or P1S. You get the same 0.6 mm ObXidian high-flow hotend as the complete assembly — 36 mm³/s in PLA, 42 mm³/s in PETG, roughly 60% more flow than the stock Bambu hotend — and supply your own heating element, temperature sensor and hotend cooling fan by transferring them from the hotend already in the machine.
A 0.6 mm nozzle changes how a P1 feels to own: walls go down in fewer perimeters, layer heights up to around 0.4 mm become practical, and long functional prints lose hours rather than minutes. It's also the friendlier size for carbon- and glass-filled filaments, which clog less readily through a wider bore — though the most abrasive composites will still wear even a hardened ObXidian tip faster than plain materials. Keep a 0.4 mm hotend on the shelf for detail work and swap between them in minutes.
