Bambu Lab X2D
Dual nozzle and a reported 65 C heated chamber in a desk-sized footprint. The one capability no P-series machine can be upgraded into.

Who the X2D is actually for
The owner whose upgrade is driven by materials, not size. If tall ASA parts split in your P1S and you do not want a floor-standing machine, this is the one printer in the range that occupies that spot — a reported 65 C actively heated chamber in a desk footprint.
Skip it if you print PLA and PETG, where the chamber buys nothing, or if you need build volume, where the reported 256 mm cube is the same wall you already have.
Passive versus active chamber, and why it is the whole argument
This distinction is worth being precise about because it is where most ABS advice goes wrong. A P1S or X1C holds heat produced by the bed. Nothing in the machine is heating the air. The chamber settles at some temperature above ambient and that is the end of the control you have — which is why "just tape the vents" is both a common suggestion and a bad one.
An actively heated chamber sets a temperature and holds it. For ABS and ASA, warm air around the whole part is what stops the lower layers cooling and contracting while the upper ones print, which is the mechanism behind both warping and layer splitting. That is not a tuning improvement, it is a different machine. What you can and cannot do about chamber temperature.
The honest limits
No extra build volume. Reported 256 mm cube, same class as a P1S. This is purely a capability upgrade.
Thin accessory ecosystem. Released April 2026, so the plates, ducts, screens and hotends that exist in abundance for the P1S mostly do not exist for this machine yet. If you like modifying your printer, that is a real cost.
Short service history. Nobody has run one for three years. For a machine you intend to depend on, waiting a few months for long-term reports is a defensible choice.
Not observed here. Stated again because it matters: this page is specification and reasoning, not first-hand use.
How it compares
P2S vs X2D is the comparison that matters if you are replacing a P1S and deciding between workflow and materials. X1C vs X2D shows how far the range has moved. H2D vs X2D is size against chamber control.

1. Best for engineering materials on a desk
Bambu Lab X2D
The materials upgrade, not the size upgrade - and the only one of those that cannot be bolted on.
Released April 2026 as a dual-nozzle machine with improvements cited to air filtration, thermal management and speed. Third-party roundups report a 256 mm cube build volume and a chamber heated to 65 C.
That chamber figure is the whole reason to care. A P1S chamber is passive: the bed warms the air, the panels keep it in, and the result is enough for ABS most of the time. An actively heated chamber is enough reliably, and it is the difference on tall ASA parts where the lower layers cool while the upper ones are still printing.
I have not run one. Everything written about the X2D on this site is specification, published positioning and reasoning, and it is labeled that way rather than dressed up as experience.
What it gets right
- Dual nozzle without stepping up to the H2 footprint — two materials on a desk-sized machine
- A reported 65 C heated chamber is a real capability jump over any passive P-series enclosure
- Newest filtration and thermal hardware in the smaller form factor
What it does not
- Released April 2026, so third-party part support is thin compared with the P1S
- Same reported 256 mm build volume as a P1S — this is a capability upgrade, not a size one
- I have not run one. What follows anywhere on this site about the X2D is specification and reasoning, not observation

Questions people actually ask
What is the X2D build volume?
Third-party lineup roundups captured in October 2026 report a 256 mm cube, which is the same class as a P1S or P2S. No official figure is stated here because bambulab.com blocks our fetches, so nothing on this page is presented as an official specification.
Does the X2D have a heated chamber?
It is reported to heat the chamber actively to 65 C, which is the main reason it is interesting for ABS and ASA. That is materially different from a P1S, whose chamber is passive - it holds heat from the bed rather than creating heat of its own.
Is the X2D worth upgrading to from a P1S?
If your problem is materials, it is the most logical step up, because an actively heated chamber is one of only two capabilities that cannot be added to a P1S with parts. If your problem is size, it does not help: the reported build volume is the same class. The two caveats are a thin accessory market and a short service history on an April 2026 release.
Is the X2D better than the H2D?
Different, not better. The H2D's advantage is build volume, reported at 350 x 320 x 325 mm, and a direct-drive dual nozzle on a large-format chassis. The X2D's advantage is a reported actively heated chamber in a desk-sized machine. Which wins depends entirely on whether your constraint is size or materials.
