Bambu Lab X2D Combo

The Bambu Lab X2D 3D printer represents the next evolutionary step in the Bambu Lab X-series, specifically engineered for high-precision multi-material 3D printing with support structures. Featuring a dual-extruder system, an actively heated enclosed build chamber, and intelligent sensor technology, the X2D is designed for printing high-quality functional parts, complex geometries, and flawless support interfaces. Combined with the AMS 2 Pro, the X2D also enables automated multi-material and multi-colour 3D printing with intelligent filament switching and integrated drying.

Dual-Extruder System with Mechanical Nozzle Switching

At the heart of the system is a dual-nozzle setup with a mechanical switching mechanism that operates without the need for an additional motor in the toolhead. Instead, a gear and ratchet mechanism handles the nozzle swap, reducing toolhead mass and minimising vibrations at high speeds.

The combination of two extrusion systems is specially designed for maximum efficiency:

• Direct Drive (Left Nozzle): Short filament path for precision model printing.
• Bowden (Right Nozzle): Optimised for support materials.

This architecture allows for simultaneous printing of model and support structures using different materials, resulting in superior surface finishes and supports that can be cleanly removed. Furthermore, the X2D's dual-extrusion system reduces overall filament waste significantly.

Tip: The Bambu Lab X2D supports all common support material combinations. For example, PLA can be combined with PETG or PVA supports, while PETG can be used with PLA, or TPU with PLA. For technical materials like PA6-CF or PET-CF, ABS or ASA can be utilised as support materials.

Dynamic Flow Calibration for Consistent Print Quality

The Bambu Lab X2D automatically manages key calibration and monitoring processes (extruder, hotend, nozzle, and filament). Before every print, the system performs a self-calibration and monitors the entire process via a vast array of sensors. A high-precision proprietary PMSM motor captures 20,000 data points per second, allowing it to detect deviations and potential clogs early on. If potential errors are identified, the printing process is paused before quality issues can occur.

Heated Build Chamber for Technical Materials

The fully enclosed design with active chamber heating up to 65 °C enables reliable printing of engineering-grade materials such as ABS, ASA, or Nylon, while "Cool Mode" provides optimal conditions for PLA and standard filaments. With a maximum nozzle temperature of up to 300 °C, the X2D covers a broad spectrum of materials.

Two thermal modes for the build chamber:

• Cool Mode: Active cooling via external air circulation for heat dissipation; optimal for standard materials like PLA and PETG.

• Heat Mode: Actively heated build chamber up to 65 °C combined with nozzle temperatures up to 300 °C; suitable for technical materials like ABS, ASA, or Nylon.

Precision, Stability, and Quiet Operation

Up to 31 integrated sensors ensure that the entire printing process is monitored - from material flow and temperature to safety-critical parameters.

*The Vision Encoder is available separately as an option. This monitors belt tension and mechanical deviations continuously, and compensates for them in real-time. This maintains a motion accuracy of up to 50 µm across the entire build volume.

Optimised for Professional Support Workflows

The X2D is specifically tailored for model-and-support combinations. While traditional dual-material printing is possible, the system architecture reaches its full potential when combining materials used for the model with dedicated support filaments.

► Bambu Lab AMS 2 Pro Multi-Material System

The Bambu Lab AMS 2 Pro is an advanced multi-material system that combines automated filament management, rapid material switching, and integrated drying. It automatically recognises the loaded filament, switches between materials independently, and ensures optimal conditions throughout the printing process.

With a capacity for up to 4 filament spools simultaneously, the AMS 2 Pro offers maximum flexibility for multi-colour and multi-material 3D printing. By expanding with up to 4 AMS 2 Pro units and 8 AMS HT modules, you can manage up to 24 filaments in parallel. The integrated high-performance servo motor enables filament changes that are up to 60% faster, reducing overall print times and optimising workflows.

A standout feature is the integrated filament drying, which handles up to four spools at once. An automatic system with an electromagnetic air valve regulates internal humidity, while rotating spools ensure uniform drying. This results in consistent material properties and stable print quality, even with moisture-sensitive filaments.
