Bambu Lab X2D 3D Printer Review

Bambu Lab has spent a couple of years being the company everyone else in desktop 3D printing gets compared to, and the X2D is the machine that replaces the printer that earned it that reputation. At $649 for the standalone unit and $899 for the Combo with the AMS 2 Pro, it slots in below the H-Series while offering something those pricier machines were supposed to own: dual-nozzle printing. Bambu is retiring the X1 Carbon outright, so this is now the default enclosed machine in the lineup.

What's here is a fairly thorough rebuild rather than a spec bump. The 256 x 256 x 260 mm build volume is familiar, but the chamber is now actively heated to 65 °C, there are 1.5GT belts, hardened nozzles, three-stage filtration with an exhaust filter, and new rods, sensors and cameras. That combination points at a fairly specific buyer: someone who wants to print engineering materials like ASA and carbon-fibre nylon without building a custom enclosure, and who wants multi-material or soluble-support work without stepping up in price. Newcomers are well served too — this is the kind of machine you can buy first and not immediately outgrow.

On the main nozzle, this is an outstanding printer. A 37-minute Benchy, clean overhangs out to 80 degrees and very little vertical banding thanks to the new belts is about as good as it gets at this price, and the heated chamber isn't a token feature — it hits a real 65 °C in roughly 20 minutes on the heater alone, and ASA, PETG and CF nylon all behave. Power consumption is sensible too, at 14 W idle and around 160 W for PLA, rising to about 330 W with the chamber hot. Roughly 22 cents for a four-hour PLA print is not a running cost anyone needs to think about.

The compromise is the second hotend. Rather than a second direct-drive extruder, it's bowden-fed from a box on the back of the machine, and the consequences are real: it caps out at 200 mm/s, strings more, has no jam or clog detection, and costs you about 20 mm of printable width on that side of the plate. On simple jobs that's ten minutes on a two-hour print; on parts printed primarily with the auxiliary nozzle it can approach double the time. The AMS situation compounds it — with a single exit port, only one nozzle can be fed automatically, so true two-material automation needs an external spool or a second AMS. Bambu Studio's filament and nozzle assignment is also still rough enough to draw criticism.

Treat the second nozzle as a convenient tool for supports and occasional two-colour work rather than a full second toolhead, and the value here is hard to argue with. Purge waste is reportedly minimal, the new filament track switch is a thoughtful touch, and across the board reviewers have landed on this as the enclosed Bambu to buy unless you specifically need H-Series build volume, the laser module or 350 °C hotends — it also makes the P2S difficult to justify. It loses half a point for the asterisk on its headline feature and the software polish, not for anything fundamental.
