Bambu Lab H2S 3D Printer Series

Topzhu Bambu Lab H2S 3D Printer

To suit your accuracy needs, correct for mechanical deviations.
Even if a printer is manufactured with extremely high precision, mechanical wear and differences are inevitable over time—but now, for the first time in the industry, a solution has been found.
Using a visual encoder, H2S achieves motion accuracy below 50 μm, unaffected by distance—fineer than a human hair. During calibration, it automatically compensates for mechanical drift, ensuring consistent accuracy and optimal performance.

One print, perfect fit
Bambu Lab's automatic hole/contour compensation feature minimizes printing tolerances, achieving machine shop-level hole dimensional accuracy.
Design critical mating components with confidence – integrate shafts, bearings, and fasteners without trial and error.
Post-printing assembly has never been easier.

Engineering wires
It features a 350 °C hot end and a 65 °C active heating chamber, supporting the entire Bambu consumable range—from PLA and PETG to PC and PPA.
H2S features closed-loop fan control and precise thermal management to minimize warpage and deformation while improving interlayer adhesion.
To create large, high-performance parts that are both functional and robust.

Smooth surface, clear edges
H2S utilizes the sensing capabilities of the servo motor on the extruder and the high-resolution eddy current sensor on the nozzle to precisely control extrusion by measuring nozzle pressure and calibrating the PA parameters of each wire, thereby improving surface smoothness and edge sharpness.

Precision movement
Active vibration compensation can instantly eliminate micro-vibrations and resonances, thereby achieving superior print quality at higher 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, thereby dynamically adjusting the electromagnetic torque vector.
The system can ensure stable extrusion and proactively detect grinding or clogging 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 problems such as material clumping, noodle-like patterns, and clogged waste trays, thereby helping to prevent printing failures.
This vision system also supports a number of advanced features, such as real-time spatial alignment for precise laser and cutting calibration, and vision encoder technology to improve positioning accuracy.
Feeding: Wire path sensors work together to monitor feed speed and position, detect wire tangling and abrasion risks, track wire mileage and spool usage, and ensure that AMS, buffers, cutters and tools on the feed path are ready, ensuring that 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 printing chamber.
The system works in conjunction with an integrated airflow sensor to actively monitor and regulate internal temperature and circulation, and maintain an ideal printing environment through real-time feedback control.
Safety: The H2S is equipped with five flame sensors, front door and roof sensors, and an emergency stop button, forming a complete safety system.
It can detect fire risks, monitor cabinet alignment, and shut down immediately when needed, thus always protecting your projects and workplace.

Artificial Intelligence Pre-Flight Checklist
Before the start of 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 identify the attributes of the printing platform.

3D printing and laser cutting.
Three modes, integrated.

Maximum output. Highest productivity.
The H2S has a print volume of 340×320×340 cubic millimeters, making it the printer with the largest print space among all Bambu Lab printers.
Your vision can be realized with a single print.

Extremely fast. More reliable.
Bambu Lab’s proprietary PMSM servo extrusion system can increase extrusion force by 67%, providing robust support for high-volume printing.
With printhead speeds up to 1000 mm/s and accelerations up to 20,000 mm/s², your H2S can finally run at full speed, reducing printing time by up to 30% while maintaining top-quality prints.

Built-in security
Laser safety window: Protects your eyes from 455 nm laser beams while keeping your workspace clearly visible.
Five flame sensors: Advanced sensors continuously monitor fire risks. Once a problem is detected, a loud buzzer and cell phone alarm will immediately notify you, allowing you to take swift action to ensure safety.
Flame-retardant compartment: This compartment is constructed entirely of fire-resistant materials, providing passive protection and increasing safety.
Emergency Stop: If you feel anything unusual, stop operating immediately - giving you complete control and greater peace of mind.

Designed with all possible connectivity and privacy
H2S provides seamless cloud connectivity, enabling remote control from any device.
For security-sensitive applications, it also provides full offline functionality to ensure physical isolation during operation.
Users can control printers, transfer files, and upgrade firmware without an internet connection.
In addition, developer mode unlocks MQTT port access, enabling developers and integrators to easily connect third-party components and custom software.

Quick nozzle change
Nozzle can be changed in seconds – no tools required, easy and convenient.
Whether you're replacing a high-flow nozzle or a nozzle of a different size, the redesigned nozzle allows for easy and intuitive operation, making it easy for even first-time users to get started.

Quiet design

The H2S is equipped with active motor noise reduction technology and professional duct noise reduction technology, and the noise level is below 50 decibels when it is running.
Even if printed overnight or in a public space, it will not disturb your environment.

All-metal die-cast body
The unibody die-cast aluminum alloy chassis is robust and stable, providing a solid foundation for high-speed, large-format printing while minimizing precision loss caused by micro-torsion.
