Dual extruder 3D printer with multi-material system AMS 2 Pro
The Bambu Lab X2D 3D printer is the next evolutionary stage of the Bambu Lab X series and has been specially developed for precise multi-material 3D printing with support structures.
With its dual extruder system, enclosed and heated print chamber, and smart sensor technology, the X2D is aimed at anyone who wants to create high-quality, functional components, complex geometries, and clean support interfaces.
In combination with the AMS 2 Pro, the X2D also enables automated multi-material and multi-color 3D printing with intelligent filament switching and integrated drying.
At the heart of the system is a dual-nozzle configuration with a mechanical switching mechanism that does not require an additional motor in the print head.
Instead, a gear and ratchet mechanism is used to change the nozzle, reducing the print head mass and minimizing vibrations at high speeds. The combination of two extrusion systems is clearly designed for efficiency: Direct Drive (left nozzle): Short filament guide for accurate printing from the model. Bowden (right nozzle): Optimized for support materials. This architecture allows simultaneous printing of the model and support with different materials, resulting in better surfaces and cleanly removable support structures. At the same time, the X2D's dual extrusion system reduces filament consumption. Tip: The Bambu Lab X2D supports common combinations of support materials for different applications. For example, PLA as the main material can be combined with PETG or PVA as support material, while PETG can be used with PLA or TPU with PLA. For technical materials such as PA6-CF or PET-CF, ABS or ASA can be used as support material. Dynamic flow calibration for consistent print quality The Bambu Lab X2D automatically handles core calibration and monitoring processes (of the extruder, hotend, nozzle, and filament). Before each print, the system performs independent calibration and monitors the entire printing process using numerous sensors. A proprietary, high-precision PMSM engine records 20,000 measurement points per second, enabling the early detection of deviations and potential blockages. If potential faults are detected, the printing process is stopped if necessary, even before quality issues arise. Heated pressure chamber for technical materials The fully enclosed design with active chamber heating up to 65°C allows for reliable printing of technical materials such as ABS, ASA, or nylon, while the cool mode offers optimal conditions for PLA and standard filaments. With a maximum nozzle temperature of up to 300°C, the X2D covers a wide range of materials.
Two thermal modes for the print chamber:
With up to 31 integrated sensors, the entire printing process is monitored, from material flow and temperature to safety-relevant parameters.
*The Vision Encoder is available separately as an option. It continuously monitors and compensates for belt tension and mechanical deviations in real time, maintaining motion accuracy of up to 50 µm across the entire build volume.
The X2D is specifically designed for model support combinations. Although classic two-material printing is also possible, the system's architecture truly shines when combining component and support materials.
The Bambu Lab AMS 2 Pro is an advanced multi-material system that combines automated filament management, rapid material changeover, and integrated drying into a single system. It automatically recognizes the filament being used, changes materials independently, and ensures optimal conditions throughout the entire printing process.
With the capacity to handle up to four filament spools simultaneously, the AMS 2 Pro offers maximum flexibility for multi-color and multi-material 3D printing. Expandable with up to 4 AMS 2 Pro units and 8 AMS HT modules, it can handle up to 24 filaments in parallel. The integrated high-performance servo motor allows for up to 60% faster filament changes, reducing print times and optimizing workflows. A key feature is the integrated filament drying system, which can process up to four spools simultaneously. An automatic system with an electromagnetic air valve regulates the internal humidity, while rotating spools ensure even drying. The result is consistent material properties and stable print quality, even with moisture-sensitive filaments.
