Bambu Lab’s X1 Carbon was discontinued on March 31, 2026, and the X2D shipped in April 2026 as its direct successor — same enclosed, actively-heated chassis, plus a second auxiliary nozzle Bambu pitches for supports and secondary materials. Independent reviewers, including CNC Kitchen, like the main printer a lot. But that second nozzle comes with real limitations worth knowing before you buy, and early owners on Bambu’s own forums have reported AMS feeding issues that haven’t fully settled since launch.

Quick answer: The Bambu Lab X2D starts at $649 solo or $899 with the AMS 2 Pro Combo, prints a 256×256×260 mm volume with a 65°C heated chamber (70°C max) and 300°C hotend, and replaces the discontinued X1 Carbon as Bambu's enclosed flagship. CNC Kitchen's independent review calls it "probably the enclosed Bambu Lab printer to get" for most buyers — but the auxiliary second nozzle is bowden-fed, slower, strings more, and has no jam detection, so it's a support/secondary-material tool, not a true second main nozzle.

The 30-second verdict

Buy the solo X2D if you want Bambu’s current enclosed flagship for less than the old X1 Carbon launched at. At $649, the active heated chamber and 300°C hotend handle ABS, ASA, and most engineering filaments that warp on passively-enclosed machines like the P1S.

Add the AMS 2 Pro Combo if you want automatic material swapping. At $899, it’s still cheaper than Bambu’s H-series Combo tiers — just plan around the single exit port, which only auto-feeds one of the X2D’s two nozzles at a time.

Treat the second nozzle as a bonus, not a reason to buy. CNC Kitchen’s testing found it genuinely useful for breakaway supports and secondary materials, but slower, stringier, and without jam detection — good enough for non-critical geometry, not a second main hotend.

What the second nozzle actually gets you — and costs you

Bambu markets the X2D’s auxiliary nozzle as a way to print supports or a secondary material without routing everything through the AMS color-swap process. In practice, per CNC Kitchen’s independent testing, that convenience comes with real tradeoffs: the second nozzle is fed by a bowden extruder mounted on the back of the machine rather than a direct-drive servo extruder like the main one, so it runs slower, uses higher retractions and lower accelerations, and strings noticeably more. Some parts printed on it took almost twice as long as the equivalent print on the main nozzle. It also has no jam or clog detection, because its feeder relies on a basic stepper motor rather than the sensor-equipped main extruder — and the hardware box housing it costs you about 20 mm of printable width on the left side of the build plate.

CNC Kitchen’s recommendation: use the auxiliary nozzle for supports, secondary materials, and non-critical geometry, not as a true second main hotend. Print quality off the main nozzle is “excellent,” but the auxiliary nozzle shows small holes on retraction spikes and visible gaps on small perimeters — good enough for a dissolvable support structure, not for a visible part surface.

The AMS single-exit-port limitation

The AMS 2 Pro Combo that ships with the X2D’s bundled tier has only one exit port, meaning it can auto-feed just one of the two nozzles at a time. Bambu’s Filament Track Switch lets a single AMS serve either nozzle, but not both simultaneously — so true automated dual-material printing (one filament per nozzle, both fed from the AMS without manual intervention) isn’t possible with a single AMS unit. Buyers who want that need an external spool holder for the second nozzle or a second AMS entirely.

Early owner reports on Bambu’s own community forum echo feeding trouble beyond just the exit-port ceiling: several threads describe filament reaching a hotend without the extruder gears engaging, triggering false jam warnings, along with scattered reports of slot-specific jams and PTFE-tube friction issues on the AMS 2 Pro. These are forum anecdotes rather than an official Bambu acknowledgment, and experiences are mixed — one owner logged 200 hours without an error, another called the setup “very clunky.” Worth a skim through the X2D section of Bambu’s forum before buying if AMS reliability is a dealbreaker for you.

X2D vs P1S: the price-overlap trap

At MSRP, the X2D’s $649 base price technically undercuts the P1S’s $699 list price — a reversal from the old X1 Carbon-vs-P1S order, where the enclosed flagship always cost more. But the P1S has been repeatedly discounted to $399-$499 by retailers including Tom’s Hardware, a price the newer X2D hasn’t matched since its April 2026 launch. If you’re comparing sticker prices, the X2D wins; if you check current sale prices first, the P1S is usually the cheaper machine in practice despite being the older, less capable one. See our full X2D vs P1S comparison for the complete spec-by-spec breakdown of what the price gap buys.

Bottom line

The Bambu Lab X2D replaces the X1 Carbon as Bambu’s enclosed flagship at a lower starting price, and CNC Kitchen’s independent review calls it “probably the enclosed Bambu Lab printer to get” for buyers who don’t need H-series build volume or 350°C hotends. Buy the solo X2D ($649) for the active heated chamber and 300°C hotend on engineering filaments. Add the AMS 2 Pro Combo ($899) for automatic material handling, but plan around the single-exit-port limit if dual-material automation matters. And treat the auxiliary nozzle as a tool for supports and secondary materials, not a second main hotend — it’s genuinely slower, stringier, and lacks jam detection compared to the primary nozzle.
