The flagship 3D printer handles multiple nozzle sizes and filament diameters through a new heating system.
Bambu Lab announced the H3C, a flagship 3D printer that uses a nine-nozzle tool-changing system to mix different material types, nozzle widths, and filament diameters during a single job. CNET reported that the machine starts at $2,500 and comes bundled with the required automated filament manager and multi-tool hardware.
The new model replaces the Vortek hotend setup found on the earlier H2C with an updated design called the Swaptek Tool Changer, according to TechRadar. The machine lets users assign fine nozzles for exterior details while shifting to larger openings for interior infill, cutting print durations while keeping clean outer surfaces.
How the Swaptek system handles filament
The Swaptek mechanism holds nine dedicated toolheads that use conductive heating. Bambu Lab stated that the setup routes electrical power and data directly to each head, bringing nozzles to printing temperatures in roughly six seconds.
That setup differs from competing mechanical changers like the INDX system used on the Prusa Core One. While the Prusa printer is tuned to skip purge towers and create less discarded plastic, the H3C still relies on a purge tower during tool swaps.
The H3C ships with nine print tools. Eight of the heads use 0.4 mm nozzles designed for standard 1.75 mm filament, while the ninth tool is a 0.4 mm head built for thicker 2.85 mm spools. Using 2.85 mm stock allows the feed mechanism to handle softer grades of TPU that would jam inside ordinary feeders. Operators can combine those thick rubbery layers with standard materials like rigid PLA inside the same project.
Dimensions and hardware specifications
The H3C is a heavy machine built for workshop environments. The core unit measures 493 by 571 by 587 mm and weighs 36.28 kg with the AMS 3H filament module installed on top. Because of that bulk, lifting and unboxing typically requires two people.
The printer provides a build area measuring 330 by 320 by 325 mm over a textured PEI build plate. Its heated bed reaches temperatures up to 120 degrees Celsius. The print chamber supports a wide variety of engineering materials, including PETG, ABS, ASA, PA, PC, PPA, and PPS.
Mounted overhead, the AMS 3H unit feeds material directly into the tool changer. The feeder unit houses nine separate filament spools and includes two dedicated bays equipped with internal heating elements to dry moisture-sensitive rolls before extrusion. The feeder is integrated directly into the machine workflow rather than acting as an optional accessory.
Print speed and workshop test results
The toolhead can travel at speeds reaching 1,400 mm/s. In hands-on testing, pushing movement rates to 125 percent speed produced heavy vibrations that knocked over purge towers and tall support structures on extended jobs. The printer automatically halted when it detected collapsed towers and alerted the operator.
Diagnostic prints showed tight temperature management, with clean performance on overhangs and bridges alongside minimal ringing artifacts. However, the machine struggled during a 0.2 mm clearance tolerance test, falling short of marks set by the earlier H2C.
To manage the machine height, Bambu Lab developed an optional rolling metal stand. Standing on the rolling cart, the printer reaches a total height of 63 inches, which makes loading rolls into the top feeder easier for standing operators.
Pricing and release schedule
Bambu Lab scheduled online orders to open on its website on 3 November 2026. The base H3C AMS Combo package costs $2,499 in the United States and £2,199 in the United Kingdom. That bundle contains the main printer, the nine-spool feeder, and all nine PrintTool heads.
The company also planned three larger packages for launch. A bundle adding a PLA palette and TPU costs $2,589, or £2,269 in the UK. Adding an open Bambu Station cart raises the package to $2,799 or £2,469. The top configuration includes an enclosed station along with an E1 air purifier for $3,049 or £2,699.
