Bambu Lab has announced the X2D, the second-generation flagship of its X Series, featuring a dual-nozzle extrusion system with mechanical switching. The base model starts at $649 in the U.S., with the X2D Combo priced at $899.
The nozzle-switching mechanism uses a system of gears and triggers with no additional motor on the toolhead, keeping the head lighter and reducing inertia at high speeds. Bambu Lab says the mechanism completed over one million switches during life-cycle testing without any degradation in performance. That lighter toolhead design also improves positioning accuracy and surface quality, the company says.
The X2D combines two distinct extrusion philosophies in one machine. The left nozzle runs a direct drive extruder, with the motor sitting directly at the toolhead for precise, short-path filament feeding. The right nozzle uses a Bowden setup, with a more powerful motor mounted at the rear of the printer and connected to the hotend via a PTFE tube, better suited for pushing filament over longer distances.
For multi-color prints in PLA or PETG, switching between nozzles replaces the lengthy purge sequences that waste filament on other multi-material setups, reducing both time and material cost per color change. The printer’s Dynamic Flow Calibration system monitors the extrusion motor, hotend, nozzles, and filament simultaneously before each print, compensating automatically for wear, moisture absorption, and environmental drift. A proprietary PMSM servo motor samples torque and position 20,000 times per second, letting the printer detect a filament jam before it escalates.
The X2D’s thermal system operates in two distinct modes. Cool Mode draws in outside air and expels warm air for clean overhangs in PLA. Heat Mode actively heats the chamber to 65°C while the nozzle reaches 300°C, opening the machine to ABS, ASA, and Nylon with reduced warping. Three-stage air filtration includes a G3 pre-filter, H12 HEPA filter, and coconut shell activated carbon. The printer runs below 50 dB and carries 31 sensors monitoring the feeding path, thermal environment, and safety status. An optional Vision Encoder brings motion accuracy to the 50-micron class.
The print area in single-nozzle mode at the main hotend is 256 x 256 x 260 mm. With both nozzles active, the intersection area is 235.5 x 256 x 256 mm. The X2D Combo is priced at $899 in the US, €849 in the EU and £769 in the UK, with the base X2D at $649, €629 and £569 respectively.
