Correct Mechanical Deviations

Even the printer come out of the factory with superb accuracy, mechanical wear and variances over time are inevitable. But now, 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. Build large, high-performance parts that are as functional as they are strong.

Even Surfaces, Crisp Edges

H2S uses both the sensing capability 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, improving surface smoothness and edge sharpness.

Precision in Motion

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

Intelligence That’s Got Your Back

20,000 Checks Per Second
Closed-Loop Feedback, Real-Time Control

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.

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 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.

Top Speed. More Reliable Than Ever.

Bambu Lab’s proprietary PMSM⁽⁵⁾ servo extrusion system delivers 67% more extrusion force, providing solid support to high flow⁽⁶⁾ printing. Paired with up to 1000 mm/s toolhead speed and up to 20,000 mm/s² acceleration, your H2S can finally go full throttle—cutting your printing time by up to 30%⁽⁷⁾—while maintaining top-tier quality.

Connectivity, By All Means.
Privacy, By Design.

The H2S offers seamless cloud connectivity for convenient remote control from any device. For security-sensitive applications, it also delivers complete offline functionality, ensuring physically isolated operation. Users can control the printer, send files, and upgrade firmware—no internet required. Additionally, Developer Mode unlocks MQTT port access, empowering developers and integrators to connect third-party components and custom software with ease.
