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 Compensation² 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.
23 Sensors + 3 Cameras
Each Potential Risk Has Its Own Detector
With AI-driven real-time monitoring, the vision system detects clumping, spaghetti and filling chute 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.
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.
Flap Switch Airflow & Filtration System
3D Printing & Laser Cutting. 3 Modes, All-in-One
High-Temp Printing
Chamber sealed. Internal air recirculates through the Air Filter and the heater to stabilize high-temp conditions. Print large engineering parts without warping.
Low-Temp Printing
Top Vent opens to bring in cool air, while maintaining a filtered exhaust⁴. Print PLA and PETG without opening the door, and handle overhangs and bridging with ease.
Laser Cutting/Engraving
Top Vent and Filter Switch Flap open. Fumes are channeled efficiently to the ventilation system, keeping your workspace safe and clean.
Bigger. Faster. Better.
Maximum Volume. Maximum Productivity.
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.

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.
DynaSense Extruder
PMSM servo extruder delivers up to 10kg of extrusion force—67% more than regular stepper motors, delivering the strongest support for high-flow printing.

Cut. Engrave. Draw.
Compact. Capable. All in One.
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.
10W 455nm Laser Power
Slice through up to 5 mm plywood, acrylic, or PU with ease—clean, fast, and precise.
Air Assist
Air Assist keeps your lines crisp by blowing away smoke and char while cooling the surface—preventing soot buildup and beam distortion for sharp, clean results.
Digital Cutting
Effortlessly cut through paper, vinyl, PU leatherette, and more—clean, accurate, and ready to apply.
Drawing
Use the drawing module to automate linework, sketches, or handwritten notes—precise, repeatable, and hands-free.
Not a Toolkit. A Production-Ready Platform.

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
Accessible. Comfortable. Made to Last.
Quick-Swap Nozzle
Swap nozzles in seconds—no tools, no hassle. Whether you're switching materials or upgrading to 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 dB¹¹. Print overnight or in shared spaces without disrupting your environment.
All-Metal, Die-Cast Body
The integrated die-cast aluminum alloy chassis delivers a sturdy, stable structure that provides a rigid foundation for high-speed, large-format printing, while minimizing accuracy loss caused by micro-twisting.
