Bambu Lab H2S Combo – Professional Large-Format Multi-Material 3D Printing System

Enclosed CoreXY printer with AMS multi-material support for high-throughput, high-precision production prints

The Bambu Lab H2S Combo is designed for professionals, engineers, and advanced makers who demand large build volume (340 × 320 × 340 mm), extreme speed (up to 1000 mm/s), and the flexibility to handle multiple materials and colors with the included AMS system. With a 350 °C hotend, actively heated 65 °C chamber, integrated sensor suite, vision system and automatic calibration, it combines high throughput with industrial-class precision and reliability. Whether you’re producing functional engineering parts, end-use components, or high-volume prototypes, the H2S Combo delivers.

Accuracy That Works for You

Correct Mechanical Deviations
Even the printer comes 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.

23 Sensors + 3 Cameras

Each Potential Risk Has Its Own Detector

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.

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 exhaust⁽⁴⁾. 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.
