Accuracy That Works for You

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.

Bambu Lab H2S

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.

Bambu Lab H2S

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

Bambu Lab H2S

Intelligence That's Got Your Back

20,000 Checks Per SecondClosed-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.

Closed-Loop Feedback, Real-Time Control


23 Sensors + 3 Cameras
Each Potential Risk Has Its Own Detector

Vision System:
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.

Feeding:
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.


Thermal 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.

Safety:
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.

Each Potential Risk Has Its Own Detector

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.

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.⁽¹⁰⁾

Bambu Lab H2S


Accessible. Comfortable.
Made to Last.

Quick-Swap Nozzle
Swap nozzles in seconds—no tools, no hassle. Whether you're switching to a high flow hotend or a different nozzle size, the redesigned hotend makes it easy and intuitive, even for first-time users.

Quiet by Design

With Active Motor Noise Canceling and specialized air duct noise-reduction technology, the H2S operates below 50 dB⁽¹¹⁾.
Print overnight or in shared spaces without disrupting your environment.
