Your Go-To Personal Manufacturing Hub

Request A Quote

The Bambu Lab H2S is a large-format, single-nozzle “personal manufacturing hub” built for speed, precision, and versatility: it pairs a 340×320×340 mm build volume with up to 1000 mm/s toolhead speed and 20,000 mm/s² acceleration (for up to 30% faster prints), adds a 350 °C hotend and 65 °C actively heated chamber for engineering-grade materials, and offers optional Vision Encoder calibration to reach <50 µm motion accuracy. AI-driven monitoring (23 sensors + 3 cameras) helps prevent failures and enables Live Spatial Alignment for the optional 10 W laser/digital-cutting module, while AMS 2 Pro/AMS HT support brings multi-color printing with integrated drying. It’s quiet (<50 dB) and can run fully offline or through the cloud—suited to both workshops and offices.

Accuracy That Works for You

Correct Mechanical Deviations

Even if the printer comes out of the factory with superb accuracy, mechanical wear and variances over time are inevitable—but now, for the first time in the industry, there’s a solution.

With the Vision Encoder⁽¹⁾, the H2S achieves distance-independent motion accuracy under 50 μm—thinner than a human hair. During calibration, it automatically compensates for mechanical drift, ensuring consistent precision and peak performance over time.

 

One Print. Perfect Fit.

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

 

Ready for Engineering Filaments

Featuring a 350 °C hotend and a 65 °C actively heated chamber. It supports the entire Bambu filament lineup from PLA and PETG to PC and PPA. With closed-loop fan control and precise thermal management, the H2S minimizes warping and deformation while improving layer adhesion. Create large, high-performance components that are both functional and robust.

Even Surfaces, Crisp Edges

H2S utilizes both the sensing capabilities of its servo motor on the extruder and the high-resolution eddy current sensors on the nozzle to precisely control extrusion by measuring nozzle pressure and calibrating PA parameters for each filament, thereby improving surface smoothness and edge sharpness.

 

Precision in Motion

Intelligence That's Got Your Back

20,000 Checks Per Second

Bambu Lab's proprietary PMSM servo system enables 20 kHz resistance and position sampling to dynamically modulate electromagnetic torque vectors. It stabilizes extrusion and actively detects grinding⁽³⁾ or clogs in real time.

23 Sensors + 3 Cameras

Each Potential Risk Has Its Own Detector

With AI-driven real-time monitoring, the vision system detects clumping, spaghetti and purge chute jamming as they happen, helping prevent failed prints before they start. This same vision system powers advanced features like Live Spatial Alignment, allowing precise laser and cutting calibration, and Vision Encoder technology, which enhances positional accuracy.

 

Filament-path sensors work in unison to monitor feeding speed and position, detect filament tangles and grinding risks, track filament mileage and spool usage, and ensure tool readiness across the AMS, buffer, cutter, and feeding paths, making sure every tool is in place and every move is under control.

 

Five NTC temperature sensors are strategically placed across the nozzle, heatbed, and chamber. Paired with integrated airflow sensors, the system actively monitors and adjusts internal temperatures and circulation, maintaining the ideal print environment through real-time feedback control.

The H2S features five flame sensors, front-door and top-cover sensors, and an emergency stop button to form a complete safety system. It detects fire risks, monitors enclosure alignment, and allows instant shutdown when needed—protecting your projects and your workspace at all times.

Pre-Flight Checklist by AI

Prior to each operational cycle, the H2S vision system initiates a comprehensive pre-flight checklist: Chamber Integrity Scan – Detects debris across the entire print surface. Hardware Configuration Audit – Instantly identifies build plate properties.

Get the Quality Filament You Need

Nothing will impact your 3D printing results like the kind of filament you use. Good filament is highly consistent in diameter, is wound evenly onto the spool with just the right amount of tension, and will not tangle when being unwound. 3D Universe offers a wide range of high-quality filaments to choose from.
