340 × 320 × 340 mm Build Volume
Print larger prototypes, functional parts and production tools with fewer assembly steps.

Bambu Lab H2S combines a generous 340 × 320 × 340 mm build volume, high-speed printing, active chamber heating and smart automation in one powerful personal manufacturing platform.
H2S combines large-format capacity, high-speed motion, engineering-material capability and smart automation in one platform.
Print larger prototypes, functional parts and production tools with fewer assembly steps.
Better thermal control for ABS, ASA, PC, PA, PPS and reinforced engineering filaments.
Up to 1000 mm/s toolhead travel speed and 20,000 mm/s² acceleration for faster production cycles.
Integrated cameras, sensors and intelligent monitoring help detect printing issues and improve process reliability.
Advanced calibration and motion control help maintain dimensional consistency across demanding prints.
With the Vision Encoder⁽¹⁾, the H2S achieves distance-independent motion accuracy under 50 μm—thinner than a human hair.
Swap nozzles in seconds—no tools, no hassle. Whether you're switching to a high flow hotend or a different nozzle size, the redesigned hotend makes it easy and intuitive, even for first-time users.
With Active Motor Noise Canceling and specialized air duct noise-reduction technology, the H2S operates below 50 dB⁽¹¹⁾. Print overnight or in shared spaces without disrupting your environment.
The integrated die-cast aluminum alloy chassis delivers a sturdy, stable structure that provides a rigid foundation for high-speed, large-format printing, while minimizing accuracy loss caused by micro-twisting.
From engineering prototypes to production tools and creative work, H2S gives teams a larger in-house fabrication platform.
Large-format Core-XY printing with high-speed motion, active chamber heating and engineering-material capability.
