Bambu Lab Launches Its Large-Format Successor to the X1C: The H2S

Today, Bambu Lab unveiled its newest 3D printer: the H2S. What makes this machine stand out from the rest of the Bambu Lab lineup? For one, it boasts the largest print volume for a single-nozzle setup that the brand has ever offered. Designed to be the “ultimate single-nozzle printer,” it combines professional-grade precision with an accessible, user-friendly package.

The H2S was developed out of community demand: users were asking for expanded capabilities and performance, but without the complications of a dual-nozzle setup. The printer offers a 340×320×340 mm³ build volume, which is 220% the volume of the X1C. Additionally, it can operate up to 30% faster than the X1C, with a toolhead speed of up to 1000 mm/s and an acceleration of 20,000 mm/s².

The Bambu Lab H2S is ideal for creating larger projects.

The temperature control is also improved in this model, with a 350°C hotend and 65°C actively heated chamber. The H2S can handle a full spectrum of engineering materials, from everyday PLA to demanding carbon fiber reinforced filaments. Furthermore, the H2S features a comprehensive monitoring system, complete with 23 sensors and 3 onboard cameras that continuously track the printing process. This intelligence network is supposed to detect issues before they become failures, ensuring reliable overnight printing and reduced waste.
