Bambu Lab H2S 3D Printer

The H2S has the largest build volume in the Bambu Lab lineup — 340 × 320 × 340mm. Full-scale helmets, large enclosures, tall functional parts, all in one piece.

Underneath the size, it's a serious machine. 350°C hotend, 120°C bed, an actively heated chamber to 65°C, and the widest material compatibility Bambu offers — including PPS and PPA composites that most desktop printers can't touch. Hardened steel nozzle and gears as standard.

1000 mm/s toolhead, 40 mm³/s flow as shipped, or 65 mm³/s with the optional high-flow hotend.

Free with your printer

Add PLA Basic to your cart alongside the printer and we'll take it off automatically at checkout — 2 free spools with the H2S and the H2S Combo, 4 free spools with the H2S 10W Combo. No code needed, any colours you like.

Both Combo configurations also include an additional 0.6mm hardened steel hotend.

Which one should I get?

Nothing is locked in at purchase. The laser, cutting and drawing modules can all be added later — the base H2S upgrades to laser capability through the Laser Upgrade Kit, which includes the safety windows and air assist pump.

The H2S 10W Combo simply saves you doing it twice. Its laser safety windows shield your eyes while keeping the workspace clear and visible, so you can watch the job without goggles.

Room to grow

The H2S supports up to 24 colours in a single print — a maximum of 4 AMS 2 Pro units plus 8 AMS HT units.

Note: Drying while printing is only supported with the AMS 2 Pro Switching Adapter, sold separately.

More than a printer

10W laser — engraves and cuts wood, leather, rubber, metal sheet, dark acrylic and stone. Up to 5mm cutting depth in basswood plywood, 400 mm/s engraving, 310 × 260mm working area. Visual positioning and micro-lidar height measurement, with flame and temperature detection built in. Rated Class 1 overall when the enclosure is properly closed.

Blade cutting and pen plotting — vinyl, stickers, paper, PVC, leather. 297.5 × 300mm cutting area, 300 × 255mm drawing area.

Cutting and drawing modules are sold separately and aren't included with any configuration here.

Filament it likes

The widest range Bambu supports. PLA, PETG, TPU, PVA, BVOH, ABS, ASA, PC, PA and PPS all run on this machine.

Composites are fully supported — carbon and glass fibre reinforced PLA, PETG, PA, PC, ABS, ASA, PPA and PPS. Hardened steel nozzle and gears are fitted as standard, so nothing needs upgrading first.

The 350°C hotend is what opens up PPS and PPA — genuinely high-temperature engineering materials that a 300°C machine can't reach.

Air handling

Three-stage: a G3 pre-filter, an H12 HEPA filter, and granulated coconut shell activated carbon, with superior-grade VOC filtration and a dedicated chamber exhaust fan.

Adequate ventilation of the work area is still recommended when running ABS, ASA, nylon or PPS — filtration reduces emissions, it doesn't remove them. If you're using the laser, ventilation ducting or the Bambu Lab Smoke Purifier is advised.

Warranty & support

1 year from date of purchase, handled by Convergent Systems Pte Ltd, Bambu Lab's authorised service partner in Singapore.

No paid setup — the printer walks you through calibration itself. But if you get stuck on settings, slicer profiles or a print that won't behave, ask us. Happy to help.

Before you order

This is a large, heavy machine — 492 × 514 × 626mm and 30kg on your bench. Boxed it's 37.5 to 45.8kg depending on configuration. Measure your space, and plan to have someone help you lift it.

Power draw peaks at 2050W at 220V. That's more than most kettles — give it a circuit it isn't sharing with much else.

Self-collection is free and worth serious consideration at this weight.
