The Bambu Lab H2S is a high-performance 3D printer engineered for speed, precision, and reliability. Building on the innovations of the H2 series, it offers advanced motion control, intelligent automation, and broad material compatibility to handle everything from rapid prototypes to demanding functional parts.
With a focus on efficiency and ease of use, the H2S empowers makers, educators, and professionals to bring complex ideas to life with exceptional consistency and quality.
Features
Correct Mechanical DeviationsWhile the H2S leaves the factory with exceptional accuracy, mechanical wear over time is unavoidable. For the first time in the industry, there’s a solution: the Vision Encoder (purcahsed separately). This system enables distance-independent motion accuracy under 50 μm—finer than a human hair—and automatically compensates for mechanical drift during calibration, ensuring long-term precision and peak performance. |
 |
 |
Perfect FitsBambu Lab’s Auto Hole/Contour Compensation reduces print tolerances to deliver machine-shop precision in hole dimensions. Create fit-critical parts with confidence—shafts, bearings, and fasteners integrate seamlessly, making post-print assembly faster and easier than ever. |
350°C Hotend & 65°C Chamber HeatingWith 65°C active chamber heating and a high-temperature hotend reaching 350°C, the H2S provides precise closed-loop temperature control. This system minimises warping and deformation in advanced materials, ensuring strong layer bonding and unlocking their full performance potential. |
 |
 |
Even Surfaces, Crisp EdgesThe H2S combines servo motor sensing on the extruder with high-resolution eddy current sensors on the nozzle to precisely control extrusion. By measuring nozzle pressure and calibrating pressure advance for each filament, it enhances surface smoothness and delivers sharper edges. |
Precision in MotionActive Vibration Compensation counteracts micro-vibrations and resonance in real time, ensuring superior print quality even at high speeds. |
 |
 |
Precise Extrusion ControlBambu Lab’s proprietary PMSM servo architecture creates an intelligent extrusion control system, performing 20 kHz torque, resistance, and position sampling to dynamically adjust electromagnetic torque. This stabilises extrusion while detecting issues such as filament grinding or clogging |
23 Sensors + 3 CamerasThe H2 series continuously monitors every aspect of the printing process—from detecting clumping, spaghetti, and purge chute jams to managing filament flow, tracking usage, ensuring tool readiness, optimizing temperature and airflow, and enabling advanced features like Live Spatial Alignment and Vision Encoder technology for precise calibration and superior accuracy. |
 |
 |
AI Pre-CheckBefore every print, the H2S’s vision system runs a full pre-flight check. It scans the chamber to detect debris, audits hardware to identify nozzle size and build plate properties, and verifies alignment between hardware settings and slicer parameters for seamless consistency. |
Large Build VolumeWith a build volume of 340 × 320 × 340 mm³, the H2S delivers the largest print capacity of any Bambu Lab printer—turning your vision into reality in a single print. |
 |
 |
Quick-Swap NozzleSwap nozzles in seconds—no tools, no fuss. The redesigned hotend makes switching to a high-flow option or different nozzle size quick and intuitive, even for first-time users. |
Quiet by DesignThanks to Active Motor Noise Canceling and optimised air duct design, the H2S runs at under 50 dB—quiet enough for overnight printing or use in shared spaces without disturbance. |
 |
 |
Multi-Colour PrintingWith the Bambu Lab Automatic Material System (AMS 2 Pro), you can seamlessly print using multiple colours and material types without the hassle of manual changes. |
Bambu Studio & Bambu Handy AppTake full control of your H2S wherever you are—use Bambu Studio or the Bambu Handy app to monitor prints remotely, record timelapse videos with the onboard camera, and explore new projects from the MakerWorld library. |
 |
 |
Optional Laser Cutting Add-OnThe Bambu Lab H2S Laser Upgrade Kit transforms the H2S into a versatile maker’s tool, expanding its capabilities beyond 3D printing. With the high-precision laser module, users can engrave detailed patterns or cut thin materials, unlocking new creative and functional applications in wood, leather, acrylic, and more |
Optional Drawing & Cutting Add-OnThe Cutting Upgrade Kit for the H2 Series expands your machine’s functionality beyond 3D printing, enabling precise blade cutting for a wide range of materials such as vinyl, paper, fabric, and more. In addition to cutting, the kit also unlocks Draw Mode, allowing the H2 to hold a pen for sketching, outlining, or adding decorative details directly onto your projects. |

Does the H2S support laser and cutting functions?
It supports 10W laser and cutting but does not support 40W laser.
Can a non-laser H2S be upgraded to a laser H2S?
Yes. The upgrade kit and its installation guide will be available some time after the product launch. Note that the upgrade kit uses an external air pump, which differs in installation structure from the built-in air pump. It must be installed externally and connected to the machine via an air tube. The upgraded printer has the same functionality and processing performance as the laser version.
Can the H2S be upgraded to an H2D?
No, it is recommended to choose the model that suits your needs when placing an order.
Is the H2S compatible with the first-generation AMS or AMS lite?
The first-generation AMS is fully plug-and-play compatible with the H2S for multi-colour printing but does not support AMS drying.
Due to fundamental differences in the feeding mechanism and buffer structure, the H2S does not support AMS lite.
How many AMS 2 Pro and AMS HT units can the H2S support, and how many colours can it print?
The H2S supports up to 4 AMS 2 Pro and 8 AMS HT units, totaling 12 units with 24 filament slots, enabling up to 24-colour printing.
Are the hotend and silicone sock of the H2S compatible with the H2D or A1?
The H2S hotend and silicone sock are compatible with the H2D. While structurally similar to the A1 hotend, they are not fully compatible. For optimal print quality, we strongly recommend not using the A1 hotend on H2 series printers. Using an H2 series hotend on an A1 printer is feasible, but it requires the H2 series silicone sock.
Are the H2S and A1 series tool heads the same? Can the components on the tool head be shared with the A1 series?
The H2S tool head features a completely new design, with optimised and upgraded components, including the extruder motor, filament drive wheel, hotend heating assembly, and cooling fan. As a result, the components on the H2S tool head are not compatible with the A1 series, except for the cutter blade.
Are the build plates of the H2S and H2D compatible?
Yes, they are compatible.
