Bambu Lab H3C review: a nine-filament 3D printer with interchangeable tools

TechRadar reviewer Alastair Jennings tested the Bambu Lab H3C 3D printer for a month. He describes it as a large, complex machine whose multi-tool design and support for different nozzle sizes and materials show potential, though the technology and software still require refinement.

The H3C uses the Swaptek Tool Changer and PrintTools, rather than the Vortek Hotend Change System found on the H2C. It can switch between 0.2 mm and 0.8 mm nozzles, using the finer nozzle for detail and the wider one for faster infill. Its PrintTool hotend also supports thicker 2.85 mm TPU filament. Jennings says learning to use these features takes time.

For a practical test, Jennings printed speaker parts with PLA outer walls and TPU infill for damping, changing nozzle sizes for different parts. He says the project showed the printer’s potential but also involved a steep learning curve with the machine and Bambu Lab software.

The AMS 3H filament system sits on top and holds up to nine filaments. It includes two slots for integrated drying and bypass feeds for specialist materials. The H3C weighs 36.28 kg with the AMS 3H and measures 493 × 571 × 587 mm. Its build area is 330 × 320 × 325 mm, and its maximum toolhead speed is 1,400 mm/s.

At the time of the test, official machine specifications and final software adjustments had not yet been released. TechRadar says the H3C is due to go on sale through Bambu Lab’s website on 3 November 2026, with one launch configuration that includes the AMS 3H and all nine PrintTools.
