Bambu Lab H2S AMS Combo
Accuracy That Works for You
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.

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.

Build large, high-performance parts that are as functional as they are strong.
23 Sensors + 3 Cameras
Each Potential Risk Has Its Own Detector
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.
23 Sensors + 3 Cameras
Each Potential Risk Has Its Own Detector
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.
23 Sensors + 3 Cameras
Each Potential Risk Has Its Own Detector
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
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.
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.
