Bambu Lab X2D

What it is

The Bambu Lab X2D is an enclosed dual-nozzle CoreXY 3D printer with a 256 x 256 x 260 mm build volume for the main nozzle and an actively heated chamber. Bambu's US store sells it on its own and in several AMS bundles; this page covers the printer on its own. It takes the place of the Bambu Lab X1 Carbon, which Bambu moved to end of life on March 31, 2026. The X2D store FAQ puts it directly: "X2D is X1C's next chapter."

Comparing the official spec sheets, the X2D doubles the X1 Carbon's top speed from 500 to 1000 mm/s, keeps 20,000 mm/s² acceleration and adds 4 mm of height. It adds a second (auxiliary) nozzle, active chamber heating to 65 °C, a toolhead camera and a three-stage filter with an H12 HEPA layer. Bed temperature is 120 °C; the X1 Carbon spec sheet lists 120 °C on 110 V power and 110 °C on 220 V. Both use a hardened steel nozzle, a 300 °C hot end and a 5-inch 1280 x 720 touchscreen.

Key specs that matter

From Bambu's official X2D spec sheet:

• Build volume: 256 x 256 x 260 mm with the main nozzle; 235.5 x 256 x 256 mm when the auxiliary nozzle or both nozzles print.
• Motion: up to 1000 mm/s and 20,000 mm/s². Rated hot end flow is 40 mm³/s, or 65 mm³/s with the optional high flow hot end.
• Hot ends: two hardened steel nozzles with hardened steel gears, up to 300 °C, 0.4 mm included. The main extruder uses a PMSM servo motor; the auxiliary extruder uses a stepper motor.
• Bed and chamber: up to 120 °C bed and active chamber heating to 65 °C.
• Air filtration: G3 pre-filter, H12 HEPA filter and coconut shell activated carbon.
• Sensors: 1920 x 1080 live view camera, 1600 x 1200 toolhead camera, door, run-out and tangle sensors, and power loss recovery.
• Electronics: 5-inch 1280 x 720 touchscreen, 8 GB eMMC with a USB port, dual-band Wi-Fi.

Who it suits

The X2D fits makers and small businesses that want engineering filaments and multi-material prints in one machine. Bambu's store says the auxiliary nozzle can print support in its own material for clean removal, combine PLA and TPU in one part, and cut purge waste during color changes. Bambu says it supports up to 25-color printing with AMS units. The heated chamber and HEPA filtration also suit ABS, ASA and nylon users who print indoors. Bambu says the X2D is UL 2904 certified for indoor air quality with its PLA Basic and PETG Basic, and rates it below 50 dB under typical conditions.

What to know before buying

At the time of writing (October 2026), the X2D was $589 on Bambu's US store (typical $649), and the X2D AMS Combo with one AMS 2 Pro was $789 (typical $899).

The two nozzles are not equal. Bambu notes that auxiliary nozzle print quality is slightly lower than the main nozzle, that official Bambu filaments are recommended on it, and that flow dynamics calibration and the servo extruder apply to the main nozzle only. Some materials, including PETG-CF and PA6-CF, are marked "print with caution" on the auxiliary hot end. Connecting more than two AMS units needs a 4-in-1 PTFE adapter.

If you need a larger build volume or hotter nozzle, compare the Bambu Lab H2D. If you do not need two nozzles or a heated chamber, the Bambu Lab P2S shares the 256 mm class build volume for less. See also our best enclosed 3D printers.
