Key features
- Large build volume: The H2S offers Bambu Lab’s largest print volume to date, measuring 340 x 320 x 340 mm³.
- High-speed printing: Equipped with a new Permanent Magnet Synchronous Motor (PMSM) servo extrusion system, the printer can reach speeds up to 1,000 mm/s with acceleration up to 20,000 mm/s², cutting print times by up to 30% compared to the X1C.
- Multi-purpose functionality: The H2S can be upgraded with additional modules to perform other tasks beyond 3D printing.
- 10W laser: Capable of cutting and engraving various materials up to 5mm thick.
- Digital cutting and drawing: A tool for cutting flexible materials and automating linework with a pen.
- Advanced temperature control: The H2S has a 350°C hotend and an actively heated chamber up to 65°C, enabling the use of high-performance engineering filaments like PC and PA, while minimising warping.
- Comprehensive AI sensing: An advanced sensor suite with 23 sensors and 3 cameras provides automated, AI-driven monitoring to detect and prevent issues like filament clumping, spaghetti failures, and nozzle pressure problems.
- Multi-colour support: The H2S is compatible with the second-generation Automatic Material System (AMS 2 Pro and AMS HT), allowing for up to 24-colour printing.
- Ease of use: The system features quick-swap nozzles, automatic calibrations for bed levelling and vibration, and offline operation capabilities.
- Safety features: Includes multiple flame sensors and a fire-resistant chassis for enhanced safety, especially when using the optional laser.
Configurations and features
The H2S is offered in several configurations:
- Base Version: Includes the core single-nozzle printer.
- AMS Combo: Bundles the H2S with an AMS 2 Pro unit for multi-colour printing. The single-nozzle design results in more purging waste compared to the dual-nozzle H2D. Up to 24 colours are possible by linking multiple AMS units.
- Laser Full Combo: Adds a 10W 455nm laser for cutting and engraving materials, along with a digital cutting module and drawing functions.
Your Go-To Personal Manufacturing Hub
Performance on a larger scale
The most immediate and striking upgrade is the build volume, which measures a generous 340 x 320 x 340 mm³. This is a significant step up from the X1C, providing the largest print area in Bambu Lab’s lineup and allowing makers to produce ambitious, single-piece projects like helmets, functional prototypes, and large-scale architectural models.
Speed is another headline feature, driven by a new Permanent Magnet Synchronous Motor (PMSM) servo extrusion system. This powerful system delivers 67% more extrusion force than its predecessors, allowing the H2S to reach toolhead speeds of up to 1,000 mm/s and acceleration up to 20,000 mm/s². This translates to print times that are up to 30% faster than the X1C on certain models.
Advanced features
- AI monitoring: An array of 23 sensors and 3 cameras detects potential issues like clogging, tangles, and spaghetti failures, pausing the print to prevent critical problems.
- Optional Vision Encoder: A separately purchased upgrade that allows for ultra-high motion accuracy of less than 50 µm for dimensionally critical parts.
- Software integration: Compatible with Bambu Studio and Bambu Handy for easy slicing and remote control.
- Robust construction: Built on a die-cast aluminium alloy chassis for stability during high-speed printing.
H2S vs. H2D: Which One Fits Your Workflow?
The Bambu Lab H2S and H2D are part of the same high-performance H2 series, but they’re designed for different priorities. If you’re focused on speed and scale, the H2S is your go-to. If you need efficient multi-material printing, the H2D might be the better fit.
Here’s a side-by-side comparison to help you decide:
| Feature | Bambu Lab H2S | Bambu Lab H2D |
| Nozzle Configuration | Single-nozzle | Dual-nozzle |
| Build Volume | Larger overall print area | Slightly smaller |
| Multi-Material Efficiency | Requires AMS for multi-material support | Built-in dual extrusion |
| Purge Waste | Higher due to single-nozzle switching | Lower due to dedicated nozzles |
| Print Speed | Faster overall print speeds | Moderate, optimised for material switching |
| Ideal Use Case | Large-format, high-speed production | Multi-material prints with minimal waste |
Accuracy That Works for You
Correct Mechanical Deviations
Even if the printer comes out of the factory with superb accuracy, mechanical wear and variances over time are inevitable—but now, for the first time in the industry, there’s a solution. With the Vision Encoder⁽¹⁾, the H2S achieves distance-independent motion accuracy under 50 μm—thinner than a human hair. During calibration, it automatically compensates for mechanical drift, ensuring consistent precision and peak performance over time.
One Print. Perfect Fit.
Bambu Lab’s Auto Hole/Contour Compensation⁽²⁾ minimises printing tolerances, delivering machine-shop-level precision for hole dimensions. Design fit-critical parts with confidence—integrate shafts, bearings, and fasteners without trial and error. Post-print assembly has never been easier.
Ready for Engineering Filaments
Featuring a 350 °C hotend and a 65 °C actively heated chamber, it supports the entire Bambu filament lineup—from PLA and PETG to PC and PPA. With closed-loop fan control and precise thermal management, the H2S minimises warping and deformation while improving layer adhesion. Build large, high-performance parts that are as functional as they are strong.
Precision in Motion
Active Vibration Compensation neutralises micro-vibrations and resonance in real time, enabling premium print quality at higher speeds.
Even Surfaces, Crisp Edges
H2S uses both the sensing capability of its servo motor on the extruder and the high-resolution eddy current sensors on the nozzle to precisely control extrusion by measuring nozzle pressure and calibrating PA parameters for each filament, improving surface smoothness and edge sharpness.
Is the Bambu Lab H2S right for you?
For makers, designers, and small businesses seeking a premium, large-format 3D printer, the H2S offers an exceptional balance of performance and price. Its expanded build volume, rapid print speeds, and advanced material capabilities make it a versatile workhorse, especially for those who primarily print in a single colour or material. While multi-colour enthusiasts might find the dual-nozzle H2D more efficient for complex projects, the H2S is undoubtedly the large-scale Bambu printer the community has been asking for.
