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.
Bambu Lab’s Second-Generation Technologies in the H2S
Bambu Lab’s H2S is equipped with the company’s proprietary, second-generation technologies, including:
- PMSM Servo Motor System: The H2S has a Permanent Magnet Synchronous Motor (PMSM) extruder, which, according to Bambu Lab, generates 67% more extrusion force than conventional extruders. Additionally, a 20kHz current feedback loop provides granular, real-time control, enabling filament adaptability and high-speed, high-quality prints.
- Vision Encoder Precision: The machine has optional Vision Encoder technology, which achieves motion accuracy under 50 microns, allowing for perfectly dimensioned parts for critical applications and smooth assembly for complex, multi-part projects.
- Auto Hole/Contour Compensation: This feature automatically compensates material shrinkage for mechanical tolerances, enabling fit-critical parts to integrate shafts, bearings and fasteners without the need for trial-and-error adjustments.
As part of the H2S Laser Full Combo configuration, the H2S completes a personal manufacturing solution. The H2S Laser Full Combo configuration combines laser engraving and cutting, digital cutting and precision drawing capabilities within the same enclosure, complete with safety features like laser-safe green glass windows. For enhanced safety, the H2S also incorporates five flame sensors, door and cover monitoring and emergency stop capabilities.
The H2S can be paired with the laser cutting modules.
Pricing: A More Accessible Option?
The H2S presents itself as a more affordable option than its dual-nozzle sibling, the H2D, making professional-grade 3D printing accessible to a broader range of creators and businesses. The new printer is launched in three configurations:
- H2S base configuration: available in October at $1,249
- H2S AMS Combo – Includes AMS 2 Pro for enhanced multi-material capabilities: available now at $1,499
- H2S Laser Full Combo (10W) – Complete manufacturing solution with laser and cutting modules: available now at $2,099
