Bambu Lab H2S Combo — Large Format 3D Printer with AMS
The Bambu Lab H2S Combo is the largest single-nozzle 3D printer in the Bambu Lab range, designed for those who need to make large-format parts without sacrificing professional-grade precision. With a build volume of 340×320×340 mm — the largest ever offered by Bambu Lab — it allows you to print bulky objects in a single piece, reducing the need to divide models into multiple sections to be assembled.
Unlike dual nozzle configurations such as the H2D, the H2S relies on a single but enhanced extruder: head movement up to 1000 mm/s, acceleration up to 20,000 mm/s² and a servo-extruder with active vibration compensation that makes it up to 30% faster than the X1C. It is the ideal choice for those looking for the performance of the H2 series without the management complexity of a dual extrusion system.
AMS 2 Pro included for multi-color and multi-material
In the Combo version, the printer comes standard with the AMS 2 Pro, which automatically handles up to 4 filaments for multi-color or multi-material printing, as well as intelligent material drying — a workflow designed for those who regularly print with multiple colors or different materials without having to manually intervene at each changeover.
Compatibility with technical materials
The hardened steel hotend reaches 350°C, while the actively heated chamber up to 65°C makes the H2S Combo compatible with a wide range of technical materials: PLA, PETG, ABS, ASA, TPU and reinforced composites. Quality control is entrusted to 23 sensors and 3 cameras, with ultra-precise automatic leveling and automatic resumption of printing after a power failure.
