Bambu Lab - H2S AMS Combo

Accuracy suitable for you, correcting mechanical deviations

Even if the printer is highly accurate when it leaves the factory, mechanical wear and differences are inevitable over time - but now, the industry has found a solution for the first time.

With the help of a visual encoder, the H2S achieves motion accuracy below 50 μm unaffected by distance - finer than a human hair. During the calibration process, it automatically compensates for mechanical drift, ensuring consistent accuracy and optimal performance.

One print, perfect fit

Bambu Lab's automatic hole/profile compensation feature minimises print tolerances, achieving workshop-level hole size accuracy.

Confidently design critical fit components - integrate shafts, bearings, and fasteners without repeated trials.

Post-print assembly has never been so simple.

Engineering-grade filament

It is equipped with a 350 °C hot end and a 65 °C actively heated chamber, supporting the full range of Bambu materials - from PLA, PETG to PC and PPA.

The H2S features closed-loop fan control and precise thermal management, minimising warping and deformation while enhancing interlayer adhesion.

Create large, high-performance parts that are both functional and robust.

Smooth surface, clear edges

The H2S utilises the sensing capabilities of the servo motor on the extruder and high-resolution vortex sensors on the nozzle to precisely control extrusion by measuring nozzle pressure and calibrating the PA parameters of each filament, thereby improving surface smoothness and edge sharpness.

Precise motion

Active vibration compensation can instantly eliminate micro-vibrations and resonance, achieving high-quality print results at greater speeds.

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, dynamically adjusting the electromagnetic torque vector.

This system stabilises extrusion and actively detects grinding or clogging issues 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 can instantly detect issues such as material clumping, noodle-like formations, and waste chute blockages, helping to prevent print failures.

This vision system also supports various advanced features, such as real-time spatial alignment for precise laser and cutting calibration, as well as visual encoder technology to enhance positioning accuracy.

Feeding: Filament path sensors work together to monitor feeding speed and position, detect filament tangling and grinding risks, track filament mileage and spool usage, and ensure that tools on the AMS, buffer, cutter, and feeding path are ready, ensuring every tool is in place and every action is under control.

Thermal control: Five NTC temperature sensors are cleverly distributed across the nozzle, heated bed, and print chamber.

The system works in conjunction with integrated airflow sensors to actively monitor and adjust internal temperature and circulation, maintaining an ideal printing environment through real-time feedback control.

Safety: The H2S is equipped with five flame sensors, front door and top cover sensors, and an emergency stop button, forming a complete safety system.

It can detect fire risks, monitor the alignment of the machine cabinet, and shut down immediately when necessary, thereby always protecting your projects and workplace. 

Artificial Intelligence Pre-Flight Checklist

Before each operational cycle begins, the H2S visual system initiates a comprehensive pre-flight checklist:

Chamber integrity scan - detects debris across the entire print surface.

Hardware configuration audit - instant identification of the print platform's attributes.

Flap switch airflow and filtration system

3D printing and laser cutting.

Three modes, integrated.

Maximum output. Highest productivity.

The print volume of the H2S is 340×320×340 cubic millimetres, the largest print space among all Bambu Lab printers.

Your vision, realised in a single print.

Ultra-fast. More reliable.

Bambu Lab's proprietary PMSM servo extrusion system can increase extrusion force by 67%, providing solid support for high-flow printing.

With print head speeds of up to 1000 mm/s and accelerations of up to 20,000 mm/s², your H2S can finally operate at full speed, reducing print times by up to 30% while maintaining top print quality.

Built-in safety

Laser safety window: Protects your eyes from the 455 nm laser beam while keeping your workspace clearly visible.

Five flame sensors: Advanced sensors continuously monitor fire risks. Once a problem is detected, a loud buzzer and mobile alerts will immediately notify you, allowing you to take quick action to ensure safety.

Flame-retardant chamber: This chamber is entirely constructed from fireproof materials, providing passive protection and enhancing safety.

Emergency stop: If something feels off, stop operation immediately - giving you complete control and peace of mind.

Connectivity and privacy designed to the fullest extent

The H2S offers seamless cloud connectivity, allowing for remote control from any device.

For security-sensitive applications, it also provides full offline functionality, ensuring physical isolation operations.

Users can control the printer, transfer files, and upgrade firmware without needing to be online.

Additionally, developer mode unlocks MQTT port access, enabling developers and integrators to easily connect third-party components and custom software.

Quick nozzle replacement

Nozzle replacement in seconds - no tools required, easy and convenient.

Whether you are replacing a high-flow nozzle or a nozzle of a different size, the redesigned nozzle allows for easy and intuitive operation, even for first-time users.

 

Quiet design

The H2S is equipped with active motor noise reduction technology and professional duct noise reduction technology, operating at noise levels below 50 decibels.

Even overnight printing or printing in public spaces will not disturb your environment.

All-metal die-cast body

The one-piece die-cast aluminium alloy chassis structure is robust and stable, providing a solid foundation for high-speed, large-format printing while minimising precision loss due to micro-twisting.
