Bambu Lab X2D Combo Review – Dual‑Nozzle 3D Printer Put Through Its Paces

When Bambu Lab announced the X2D Combo, the promise was simple: two nozzles, ultra‑fast prints, and a price that still feels reachable for serious hobbyists. The reality? A mixed bag of impressive speed gains, a few annoying quirks, and a machine that demands a bit of patience to master.

First impressions matter, and the X2D doesn’t disappoint on looks. Its sleek, all‑metal frame feels solid, and the integrated touchscreen adds a dash of modern flair. Yet, the moment you power it up, you’ll notice the fan noise – it’s louder than a typical desktop PC, especially during the initial heat‑up phase. Not a deal‑breaker, but something to be aware of if you work in a quiet studio.

Printing speed is where the X2D really shines. With the dual‑nozzle setup you can run a standard PLA on the 0.4 mm nozzle while simultaneously feeding a dissolvable support material through the 0.2 mm companion. In our tests, a 150 mm tall lattice tower that usually takes 45 minutes on a comparable printer was finished in just 22 minutes. The time savings are real, though they come with a slightly higher power draw – the machine peaks at about 250 W during rapid moves.

Accuracy, however, is a more nuanced story. For rigid filaments like PLA and PETG the X2D consistently delivers <0.1 mm dimensional fidelity, which is on par with the best single‑nozzle desks. When we switched to TPU, the flexible filament tended to slip a bit under the higher feed rates, leading to occasional stringing. Dropping the speed by roughly 30 % solved the issue, but it also eroded the primary selling point of “speed without compromise.”

One feature that truly sets this printer apart is its automatic bed leveling combined with a mesh‑based correction system. The sensor probes the build surface in under a minute, and the firmware applies micro‑adjustments during the print. In practice, this means the first layer sticks reliably, even after moving the machine from one room to another. The only downside? The leveling routine can be a bit temperamental if the build plate is dusty; a quick wipe restores normal operation.

We also put the dual‑extruder system to the test with multi‑material prints – a small gear with built‑in over‑hangs supported by the second nozzle’s PVA. The dissolvable support dissolved cleanly in warm water, leaving crisp edges on the main part. This is a major convenience for designers who need intricate internal structures without the hassle of manual support removal.

From a software standpoint, Bambu Studio feels polished but still a touch beta‑ish. The slicer offers a handful of presets for the X2D, yet we found ourselves tweaking retraction settings manually for the best results with flexible filaments. The community is growing fast, and third‑party plugins are beginning to appear, which should smooth out these rough edges over time.

In terms of price, the X2D Combo sits at roughly $1,500 USD, which is steep compared to a vanilla single‑nozzle printer but still under many industrial dual‑extruder systems. If you value the time saved on complex prints and appreciate the convenience of automatic leveling, the cost starts to make sense.

Bottom line: the Bambu Lab X2D Combo delivers on its headline promise of fast, dual‑material printing, but you’ll need to dial in settings for flexible filaments and keep the build plate clean. For users who regularly need support‑free geometries, it’s a compelling option worth the investment.
