Accuracy That Works for You – Correct Mechanical Deviations

Even though printers 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 Compensation⁽²⁾ minimises 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 minimises 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 neutralises 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 stabilises extrusion and actively detects grinding⁽³⁾ or clogs in real time.

23 Sensors + 3 Cameras

Each Potential Risk Has Its Own Detector

Vision System

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.

Feeding

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.

Thermal 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.

Safety

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.

Pre-Flight Checklist by AI

Before 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.

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 stabilise 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

Flap Switch Airflow & Filtration System

Top Vent and Filter Switch Flap open. Fumes are channelled 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.

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.
