# Bambu Lab H2S review

Big single nozzle enclosed printer for large and engineering prints

- Our score: 6.1 out of 10
- Price: $1,049 (checked Nov 4, 2026)
- Status: on sale
- Best for: large prints and engineering filaments
- Skip if: you print lots of multi color models
- HTML version: https://robotsforthat.com/robot/bambu-lab-h2s/

## Verdict

The H2S gives you the big heated chamber of Bambu Lab's H2 line with one nozzle, so you get large builds without dual nozzle dead zones. It suits makers printing big parts, batches and engineering filaments like ABS, ASA and nylon. Skip it if you do a lot of multi color or soluble support work, since single nozzle color swaps waste filament and run slower than on the H2D.

## Pros

- Large 340 x 320 x 340 mm build volume
- Heated chamber up to 65 C for ABS, ASA and nylon
- 350 C hotend with quick change nozzles
- Optional laser and cutting modules
- Polished guided setup and app

## Cons

- Multi color jobs purge a lot of filament
- No tool changer, so soluble supports are less practical
- Heavy, about 30 kg, and needs two people to unbox
- Costs much more than a P2S

## Specs

- build volume: 340 x 320 x 340 mm (Bambu Lab)
- print speed: Up to 1,000 mm/s toolhead speed, 20,000 mm/s2 acceleration (Bambu Lab)
- multi color: Yes with AMS 2 Pro (AMS Combo version); single nozzle, so color changes purge filament. CGMagazine says chained AMS units can hold 16 or more spools
- enclosure: Yes, fully enclosed with active chamber heating up to 65 C (Bambu Lab)
- auto leveling: Yes, automatic calibration; first run calibration took about 30 minutes for The Gadgeteer
- max nozzle temp: 350 C (Bambu Lab)
- heated bed: Yes, up to 120 C (CGMagazine, The Gadgeteer)
- filament types: PLA, PETG, TPU, ABS, ASA, PC, PPA, PA6 GF, PAHT CF and other fiber filled engineering filaments (Bambu Lab)
- connectivity: Cloud, LAN, full offline mode, USB drive (not included); MQTT access in Developer Mode (Bambu Lab)
- camera: Yes, 3 cameras including a top down BirdsEye camera and a toolhead camera, with AI failure detection (Bambu Lab)
- noise: Below 50 dB (Bambu Lab claim, measured at 1 m)
- assembly: Ships assembled; CGMagazine says unboxing needs two people and setup with calibration can take more than 30 minutes
- weight: 30 kg printer alone, 40.7 kg AMS combo (The Gadgeteer)

## Safety

- recalls: No recall found for this model as of 2026-10-30 (web search of cpsc.gov for 3D printer recalls by Creality, Bambu Lab, Elegoo, Sovol, Snapmaker and Flashforge; only the Bambu Lab A1 appeared)
- fcc: Not checked
- company status: Active

## Questions buyers ask

### How is the H2S different from the H2D?

The H2S has one nozzle instead of two. That gives it a full 340 x 320 x 340 mm build area with no dual nozzle dead zones, but multi color prints purge more filament and run slower, per CGMagazine and The Gadgeteer.

### Can the H2S print ABS and nylon?

Yes. It has an enclosed chamber heated up to 65 C, a 350 C hotend and a 120 C bed, and Bambu Lab lists ABS, ASA, PC and nylon composites.

### Does it work with a laser?

Yes, with the optional 10 W laser module. Creative Bloq notes it does not support the 40 W laser.
