Bambu Lab H2S AMS Combo 3D Printer

The Bambu Lab H2S AMS Combo brings the full H2S large-format platform together with the AMS 2 Pro multi-colour and filament drying system in a single ready-to-run package. The 340 × 320 × 340 mm³ build volume — Bambu Lab's largest to date — handles full-scale functional parts, prototypes, jigs, and design models in one print, while the 350 °C hotend and 65 °C actively heated chamber extend material compatibility from PLA and PETG through PC, PA, PPS, and carbon and glass fibre composites. With the AMS 2 Pro pre-installed, multicolour printing is available from first power-on without additional setup.

At its core is a proprietary PMSM DynaSense servo extruder delivering up to 10 kg of extrusion force with 20 kHz real-time sampling for clog and grinding detection. The result is stable high-flow output at 1000 mm/s toolhead speed and 20,000 mm/s² acceleration, with Active Vibration Compensation maintaining edge sharpness and surface smoothness at speed. Vision Encoder technology achieves motion accuracy under 50 μm through optical calibration, with automatic mechanical drift compensation ensuring consistent dimensional precision over the machine's full service life.

The AMS 2 Pro supports 4 filament slots with active auto-venting filament drying, RFID auto-matching for Bambu filaments, and compatibility with up to 4 AMS 2 Pro and 8 AMS HT units for up to 24-colour printing. AI-driven monitoring runs across 23 sensors and 3 cameras with real-time spaghetti, clog, and purge chute jam detection, backed by five flame sensors, door and cover sensors, and an emergency stop button for full unattended operation safety. A die-cast aluminum alloy chassis and Active Motor Noise Canceling below 50 dB make the H2S AMS Combo equally at home in a production facility or a design studio.
