A soft watch strap, a rigid case and a tiny detailed dial, all coming off the build plate in the same print job. That’s the pitch for Bambu Lab’s H3C.
It’s Bambu’s first toolchanger, and it keeps nine separate print tools loaded, so the printer swaps heads instead of pushing every color through one nozzle. The H3C Combo with the AMS 3H filament system is $2,499 before tax. That’s MacBook Pro money for a printer.

Nine tools, no unloading
Each tool gets its own filament path and heater, so the next material sits loaded while another one prints. Bambu’s Active Pre-Heat goes one step further, reading ahead in the job and warming the next tool before it’s needed.
Bambu rates swaps at as little as six seconds, with about 0.038 grams of purge per change. That’s barely a crumb. But those are best-case internal numbers with PLA Basic, and other materials run slower.
The catch: the box ships with a 2.85mm tool for flexible filament, so running nine colors of standard 1.75mm filament needs one more 1.75mm PrintTool.
Hard and soft parts in one job
Bambu’s Maker Watch demo shows it best: a 0.2mm nozzle prints the dial, a 0.4mm nozzle prints the case and a TPU tool prints the strap. You still finish and assemble it yourself, and you supply the watch movement.
That’s the part that made me look twice. You pick the material for what each piece actually does, instead of printing everything in one plastic and gluing it together later. Mixed nozzle sizes (0.2, 0.4, 0.6 and 0.8mm) need hotends sold separately, though.
Five colors that blend into gradients
The CMYKW PLA Palette layers cyan, magenta, yellow, black and white to build in-between shades, the way a color printer mixes ink, except here it’s stacked plastic. Fast swaps keep all that layering from turning into a pile of purge waste.
If you want the colorful demo prints, the $2,589 starter pack adds PLA Palette and TPU filament for $90 over the base Combo.
Nine spools, two dryers
All nine rolls live inside the enclosed AMS 3H, right in the printer’s footprint, and it reads RFID tags for material, color and weight left. Two slots dry filament at up to 85°C, even mid-print.
Slot eight is the busy one. It holds the flexible tool and doubles as a dryer, and Bambu’s own TPU goes as soft as 75A. Older AMS units, sold separately, can push the total to 24 materials.
It needs real floor space
Forget the dorm desk. With the AMS 3H on top, the H3C stands 1,016mm tall (about 40 inches) and weighs 36.28kg, about 80 pounds, so Bambu wants it on the floor or a low, stable surface.
| H3C spec | Rating |

| Max nozzle temp | 350°C |
| Max bed temp | 120°C |
| Chamber heating | Up to 65°C |
| Size with AMS 3H | 493 x 571 x 1016mm |

CutTool, DrawTool and DebossTool add cutting, drawing and embossing as optional extras, and the BirdsEye camera upgrade isn’t due until the first half of 2027.
Who should buy it
For the big enclosed format without nine tools, start with the Bambu Lab H2S review. And the A1 mini and LED lamp kit is a much smaller first step if you’re new to printing.
H2D, H2C and X2D owners get mixed-nozzle updates from November 2026 into early 2027. So don’t replace a working printer for that alone. The 12-nozzle AtomForm Palette 300 takes a different shot at the same no-waste idea.

This one’s for you if you already design parts that need different materials. Shopping for a first printer? Skip it and grab one that costs a third as much.
