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.
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.
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.

65 °C Heated Chamber
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.
Active Vibration Compensation neutralizes micro-vibrations and resonance in real time, enabling premium print quality at higher speeds.
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 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.
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.
With a build volume of 340×320×340 mm³, the H2S offers the largest print space among all Bambu Lab printers. Your Vision. Fully Realized in One Print.
Full Scale Printing: Print bigger, with fewer plates
Live Spatial Alignment
Top-down BirdsEye camera⁽⁸⁾ and onboard toolhead camera enable Live Spatial Alignment, letting you preview the toolpath directly on your material with 0.3 mm accuracy. What you see is what you get.
Auto Arrangement
Bambu Suite automatically arranges your project shapes to make the most of every sheet—smart, efficient, and effortless.
Safety, Built In
Shield your eyes from the 455 nm laser beam while keeping your workspace clear and visible.
Advanced sensors continuously monitor for fire risks. If an issue is detected, a loud buzzer and mobile alert⁽⁹⁾ notify you immediately—so you can act fast and stay safe.
Constructed with fire-resistant materials throughout, the chamber provides passive protection for added safety.
Immediately halt operations if something feels off—giving you full control and added peace of mind.

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.
