Bambu Lab H2S – Large-Format, High-Speed Bambu for Demanding Work

The Bambu Lab H2S is a fully enclosed, large-format CoreXY printer designed for serious makers, schools and small businesses that need big, accurate parts without constant babysitting. The feature overview graphic above highlights what makes the H2S special: full filament-path AI detection, 10–30% faster print times, 65°C active chamber heating, a servo-driven extruder, vision-encoded motion control, a 340 × 320 × 340 mm³ build volume, smart airflow, and optional cutting/engraving tools.

Envirolaser3D brings the H2S Series to Canadian customers with H2S, H2S AMS Combo and H2S Laser 10W variants, so you can choose the right mix of large-format printing, multi-material automation and laser engraving for your workflow.

Full Filament Path AI Detection

The H2S constantly monitors the entire filament path to catch problems before they ruin a print. The system uses sensors along the path to detect anomalies and can pause automatically so you don’t waste hours of print time and material.

The filament tangle detection graphic shows how a slider and spring-based sensor detects excessive resistance. When tension spikes (for example, from a knot in the spool), the printer pauses to prevent “air printing” and lets you fix the issue.

This combination of AI error detection and mechanical sensing makes the H2S far more reliable for long, tall prints than traditional desktop 3D printers.

Cut Printing Time by 10–30%*

The H2S is tuned for high-speed printing, with a toolhead capable of up to 1000 mm/s and high acceleration.

Bambu’s motion system, slicer profiles and high-flow nozzle work together to cut print times by roughly 10–30% compared to typical high-end desktop printers, while still maintaining excellent surface quality. For production work, props, or repeated functional parts, that time savings adds up quickly.

65°C Active Chamber Heating for Tough Materials

The chamber infographic highlights the 65°C active chamber, 120°C max bed and 350°C max nozzle temperatures. 

This combination gives you:

• Much better results on ABS, ASA, PC, PA and fibre-reinforced materials

• Reduced warping and layer separation on large parts

• Better layer adhesion and mechanical performance

With the H2S, you can tackle serious engineering filaments while still enjoying the convenience of a compact, enclosed printer.

Servo Motor Extruder with More Extrusion Force

Vision-Encoded 50 μm Motion Accuracy

The vision encoder graphic represents the H2S’s vision-encoded motion control, which achieves 50 μm motion accuracy.

By continuously measuring and correcting motion, the printer can maintain:

• Crisp edges and fine details
  

• Accurate dimensions across the full build volume
  

• Stable performance even after long use

For users upgrading from basic bedslingers or older CoreXY printers, this level of control is a big step up in repeatability.

Large 340 × 320 × 340 mm³ Build Volume

The “Cut – engrave and draw” infographic represents the H2S Laser 10W configuration. When you choose this variant, you get an integrated 10 W blue diode laser for engraving and cutting, plus support for cutting and drawing tools.

Key laser specs from the table below the images:

• Engraving laser: 455 nm ± 5 nm blue light
  

• Height measuring laser: 850 nm ± 5 nm infrared light
  

• Max engraving speed: 400 mm/s
  

• Max cutting thickness: 5 mm basswood plywood
  

• Engraving area: 310 × 260 mm²
  

This lets you turn your H2S into a hybrid fabrication system for signs, custom gifts, enclosures and more — without buying a separate laser cutter. 

Smart Auto Airflow & Filtration for Different Materials

The airflow graphic shows the H2S’s flap switch airflow and filtration system, which automatically adjusts how air moves through the chamber based on the material and process.

For example:

• High-temperature materials benefit from recirculated warm air to minimise warping.
  

• PLA and similar filaments can be printed with controlled, filtered airflow, helping maintain quality while managing fumes.

This makes the H2S more versatile in real-world environments like classrooms, offices and small workshops.
