Bambu Lab H2S Laser Full Combo - 3D Printer

One nozzle. Full manufacturing hub.

The H2S trades the H2D's second nozzle for scale — a 340 × 320 × 340 mm build volume, 120% larger than the X1 Carbon, so full-size models print in one go without upscaling or assembly. The Laser Full Combo turns that same enclosure into an engraver and cutter, so one machine covers printing, laser work, digital cutting, and pen drawing.

Extrusion that corrects itself in real time

A proprietary PMSM servo extruder samples resistance and position 20,000 times per second, delivering 67% more extrusion force than conventional designs while actively catching grinding or clogs as they happen. High-resolution eddy current sensors on the nozzle read pressure and auto-calibrate pressure advance per filament, so surfaces come out smooth and edges stay sharp.

Precision that doesn't drift

The optional Vision Encoder holds motion accuracy under 50 µm and automatically compensates for mechanical wear over time — accuracy the machine maintains rather than just ships with. Active vibration compensation cancels micro-resonance in real time, so print quality holds even as speed climbs toward 1000 mm/s and 20,000 mm/s² acceleration.

23 sensors, 3 cameras, one job: catch problems first

A full-path AI detection system tracks flow, temperature, and filament usage while onboard cameras watch for tangled filament, foreign objects, or a failed print — all before it wastes a spool.

Built to run hot and cold, safely

A sealed chamber recirculates heated, filtered air up to 65 °C for warp-free engineering prints, while a top vent brings in cool air for PLA and PETG without opening the doors. Switch to laser mode and the same vent system redirects fumes out through a G3 pre-filter, H12 HEPA filter, and coconut-shell activated carbon filter. Five flame sensors, door and lid monitoring, and a physical emergency-stop button back it all up — safety features specifically built around the laser's presence.

Cut, engrave, draw — no separate machine needed

The included 10W laser module (H2S supports 10W only, not 40W) handles engraving and cutting up to 5 mm of basswood plywood, with a laser-safe enclosure and safety-rated glass windows. A digital cutting module and pen holder round out the Full Combo for vinyl-style cutting and precision drawing.
