Product details
Features & specifications
Bambu Lab H3C Combo is a 9-material tool-changing 3D printer paired with the AMS 3H, a fully enclosed system that stores, feeds, and dries filament inside the machine. It is built for makers, designers, and engineers who want to combine colors and materials in one print, from multicolor models to flexible TPU and engineering-grade parts, while keeping purge waste low.
Highlights
- Nine PrintTools with Swaptek. Each PrintTool has its own filament path and heater, so every material stays loaded and ready. Active Pre-Heat warms the incoming nozzle while the current one is still printing. Under optimal test conditions with PLA Basic, material changes take as little as 6 seconds and purge as little as 38mg; actual results vary with filament type and slicer settings.
- Enclosed filament handling. Drop filament into any of the AMS 3H's nine slots and it is detected, routed, and loaded into the matching PrintTool automatically. A built-in 2-slot dryer reaches 85°C for PA, PC, and carbon-fiber-filled filaments, drying on demand or, with selected filaments, during a print.
- Soft TPU printing. The FlexFeed extruder handles 1.75mm and 2.85mm filament and prints TPU as soft as 75A. The included 2.85mm PrintTool feeds through the bypass and resists buckling, reaching up to 3× the maximum flow rate of the previous-generation machine in internal testing.
- Mixed nozzle sizes. Carry different nozzle sizes in one job, so fine details and larger areas can each print at a suitable layer height.
- Engineering materials. 350°C hardened steel nozzles and active chamber heating up to 65°C support materials such as ABS, PC, PA-CF, and PET-CF.
- Automated setup and monitoring. PrintTool docking calibration, offset compensation, and bed leveling run automatically before every print, and AI monitoring watches for spaghetti, purge-bin jams, and clogs.
