H2S-Combo Bambu Lab

Precision that works for you

Correction of mechanical deviations

Even printers that come out of the factory with extreme precision, over time mechanical wear and variation is inevitable – but now, for the first time in the industry, there is a solution. With the Vision Encoder⁽¹⁾, H2S achieves distance-independent motion accuracy of less than 50 μm – thinner than a human hair. During calibration, it automatically compensates for mechanical drift, ensuring consistent precision and maximum performance over time.

One print. Perfect fit.

Bambu Lab’s Auto Hole/Contour Compensation⁽²⁾ minimizes printing tolerances, providing machine-workshop level precision for hole dimensions. Design parts with critical fit with confidence – integrate shafts, bearings and fasteners without trial and error. Post-print assembly has never been easier.

Ready for engineering filaments

With a 350°C hot head and an actively heated 65°C chamber, it supports the entire range of Bambu filaments from PLA and PETG to PC and PPA. With closed-loop fan control and precision thermal management, H2S minimizes distortion and warpage while improving ply adhesion. Build large, high-performance parts that are as functional as they are tough.

Flat surfaces, sharp edges

H2S uses both the extruder’s servomotor sensing capabilities and the nozzle’s high-resolution eddy current sensors to precisely control extrusion by measuring nozzle pressure and calibrating PA parameters for each filament, improving surface smoothness and edge sharpness.

Precision on the move

Active Vibration Compensation neutralizes micro-vibration and resonance in real time, enabling high print quality at higher speeds.

Intelligence that supports you

20 000 checks per second

Closed-loop feedback, real-time control

Bambu Lab’s patented PMSM servo system enables 20 kHz resistance and positional sampling to dynamically modulate electromagnetic torque vectors. It stabilizes extrusion and actively detects friction⁽³⁾ or blockages in real time.

23 sensors + 3 cameras

Each potential risk has its own detector

Using AI-guided real-time monitoring, the vision system detects clumping, spaghetti and ejection channel blockages as they happen, helping to prevent failed stamps before they start. This same vision system powers advanced features such as Live Spatial Alignment, enabling precise laser and cutting calibration, and Vision Encoder technology that improves positioning accuracy.

Pre-press check by AI

Prior to each operational cycle, the H2S vision system runs a comprehensive pre-flight inspection: the Camera Integrity Scan – detects debris across the entire print surface. Hardware configuration check – immediately identifies build platform properties.

3D printing and laser cutting. 3 modes, all in one

Bigger. Faster. Better.

Maximum volume. Maximum performance.

With a build volume of 340×320×340 mm³, the H2S offers the largest print space of any Bambu Lab printer. Your vision. Fully realised in one print.

Maximum speed. More reliable than ever.

Bambu Lab’s patented PMSM⁽⁵⁾ servo extrusion system delivers 67% greater extrusion force, providing solid support for high flow⁽⁶⁾ printing. Combined with a tool head speed of up to 1000 mm/s and acceleration of up to 20,000 mm/s², your H2S can finally run at full power, reducing print times by up to 30%⁽⁷⁾ while maintaining the highest quality.

Connectivity in every way. Privacy by design.

H2S offers seamless connectivity to the cloud for convenient remote control from any device. For security-sensitive applications, it also offers full offline functionality providing physically isolated operation. Users can manage the printer, send files, and update firmware-without the need for the internet. In addition, developer mode unlocks access to the MQTT port, enabling developers and integrators to easily connect third-party components and custom software.¹⁰
