Bambu Lab — H Series Flagship
Bambu Lab H3C Combo
The ultimate 9-material tool changer 3D printer. SwapTek technology swaps tools in 6 seconds, five PrintTools blend CMYKW into full-spectrum color, and a dedicated 2.85mm tool prints ultra-soft TPU — all inside a fully enclosed, actively heated chamber.
Bambu Lab H3C Combo — complete multicolor and multi-material printing system
Nine Tools. Zero Compromises.
The H3C is Bambu Lab's first true tool changer, featuring nine independent SwapTek PrintTools — each with its own hotend, extruder, and dedicated filament path. Tools swap in approximately 6 seconds (3.4 seconds for the mechanical change), dramatically faster than the 40-second filament retractions of single-nozzle systems. Mix nozzle sizes, materials, and colors in a single print without limitation.
Full-Spectrum CMYKW Color Mixing
Five PrintTools handle CMYKW (Cyan, Magenta, Yellow, Key/Black, White) filaments simultaneously, blending them into millions of colors directly during printing. Combined with the AMS 3H's nine-spool capacity, the H3C produces photorealistic multicolor prints, intricate artistic designs, and functional parts with full-color labeling — all in a single continuous print job.
2.85mm FlexFeed — The Soft TPU Game Changer
One dedicated PrintTool accepts 2.85mm filament, enabling reliable printing of ultra-soft TPU down to Shore 60A — softer than most 3D printers can handle. Print flexible grips, shoe soles, vibration dampeners, and wearable items at speeds faster than many printers achieve with rigid PLA. Additional 2.85mm tools are available separately.
Integrated AMS 3H Filament Management
The new AMS 3H sits atop the printer as a permanent, integrated unit with capacity for nine spools — one for each tool. It features active drying for two spools simultaneously, keeping engineering filaments like nylon and PC dry during long prints. The transparent design lets you monitor filament status at a glance, while the elevated position saves valuable workspace below.
Extreme Speed with Precision
With a maximum toolhead speed of 1,400 mm/s and acceleration of 25,000 mm/s², the H3C is Bambu Lab's fastest printer. Travel speed is 40% higher and travel acceleration 150% greater than the H2 series, enabling both rapid tool changes and faster single-material prints. The CoreXY motion system maintains precision even at extreme velocities.
Engineering-Grade Materials
The fully enclosed build chamber with active heating up to 65°C, combined with a 120°C bed and 350°C hardened steel nozzle, handles the full spectrum of engineering materials: PLA, PETG, ABS, ASA, Nylon (PA), Polycarbonate (PC), carbon-fiber and glass-filled composites, and high-temperature polymers including PEI, PEEK, and PEKK. HEPA and activated-carbon filtration makes it suitable for office and educational environments.
AI-Powered Monitoring and Control
A built-in camera with AI failure detection monitors every print, alerting you to spaghetti failures, foreign objects, and other anomalies in real time. The 5-inch tilting touchscreen provides intuitive on-device control, while 64GB of internal storage eliminates the need for external USB drives. Connect via Wi-Fi or operate in LAN-only mode for complete privacy.
Mixed Nozzle Sizes in One Print
Pair different nozzle diameters across the nine tools — use a large nozzle for rapid infill and structural sections while a fine nozzle handles detailed perimeters and surface features. Bambu Studio's mixed-diameter toolpath planning automatically assigns the optimal tool to each geometry, maximizing both speed and detail without manual intervention.

Important Notes
- The AMS 3H is required for operation and is included in the Combo package
- With AMS 3H installed, total height exceeds 1 meter — ensure adequate vertical clearance
- 2.85mm and 1.75mm PrintTools are not interchangeable — each requires its own complete tool
- Additional PrintTools and nozzles available separately
- Wi-Fi connectivity only — no Ethernet port
- Initial calibration takes approximately one hour
- Prime tower waste is reduced compared to single-nozzle AMS systems but not eliminated (~50mg per change)
