Precision that works for you

Corrects mechanical deviations
While the printer leaves the factory with high precision, mechanical wear and small variations over time are inevitable. For the first time in the industry, the H2S offers a solution: With Vision Encoder⁽¹⁾, the printer achieves motion precision below 50 μm – thinner than a human hair – regardless of distance. During calibration, the system automatically compensates for mechanical drift, ensuring consistent precision and maximum performance over time.

One print. Perfect fit.
Bambu Lab's Auto Hole/Contour Compensation⁽²⁾ minimizes print tolerances, delivering machine-shop level precision for holes and dimensions. Design parts where fit is critical with confidence – integrate shafts, bearings, and fasteners without guesswork. Subsequent assembly has never been easier.

Ready for engineering filaments
With a 350 °C nozzle and an actively heated 65 °C chamber, the H2S supports the entire Bambu filament line – from PLA and PETG to PC and PPA. With closed-loop fan control and precise temperature management, the printer minimizes warping and deformation while improving layer adhesion. Print large, high-performance parts that are both functional and strong.

FAQ - Frequently Asked Questions

1. Does the H2S support laser and cutting functions?
   It supports 10W laser and cutting, but does not support 40W laser.

2. Can an H2S without a laser be upgraded to a laser H2S?
   Yes. The upgrade kit and installation guide will be available some time after product launch. Please note that the upgrade kit uses an external air pump, which differs in installation structure from the built-in air pump. It must be installed externally and connected to the machine via an air hose. The upgraded printer has the same functionality and processing performance as the laser version.

3. Can the H2S be upgraded to an H2D?
   No. It is recommended to choose the model that suits your needs when ordering.

4. Is the H2S compatible with the first generation AMS or AMS lite?
   The first generation AMS is fully plug-and-play compatible with the H2S for multi-color printing, but does not support AMS drying. Due to fundamental differences in the feeding mechanism and buffer structure, the H2S does not support AMS lite.

5. How many AMS 2 Pro and AMS HT units does the H2S support, and how many colors can it print?
   The H2S supports up to 4 AMS 2 Pro and 8 AMS HT units, a total of 12 units with 24 filament slots, enabling up to 24-color printing.

6. Are the hotend and silicone sock on the H2S compatible with the H2D or A1?
   The H2S hotend and silicone sock are compatible with the H2D. Although they are structurally similar to the A1 hotend, they are not fully compatible. For optimal print quality, we strongly recommend not using the A1 hotend on H2 series printers. It is possible to use an H2 series hotend on an A1 printer, but it requires the H2 series silicone sock.

7. Are the tool heads on the H2S and A1 series similar? Can components be shared with the A1 series?
   The H2S tool head has a brand new design with optimized and upgraded components, including the extruder motor, filament drive wheel, hotend heating unit, and cooling fan. Therefore, the components on the H2S tool head are not compatible with the A1 series, except for the cutting blade.

8. Are the build plates for H2S and H2D compatible?
   Yes, they are compatible.

9. Does the H2S support motion accuracy calibration, and is the calibration plate from my previously purchased H2D compatible?
   It supports motion accuracy calibration, and the H2D calibration plate is compatible.

10. The AMS 2 Pro connects via a 6-pin connector. What are the two remaining 4-pin connectors on the back of the H2S used for?
    The two 4-pin ports on the back are reserved for future expansion accessories. For example, one of these ports can be used to connect an external air pump when upgrading from a non-laser version to a laser version.

11. Does the H2S come with a USB drive, and what functions are affected without it? What are the USB requirements?
    The package does not include a standard USB flash drive. You can still start prints normally without a USB, as the printer has built-in storage for running print files. However, without an inserted USB drive, the following functions will be affected:
    a. Recording and timelapse photography cannot be activated.
    b. Prints cannot be started via LAN.
    c. Print files cannot be sent to the machine for storage via Bambu Studio.
    d. Log files cannot be exported.

USB requirements: USB 2.0 or newer (actual minimum write speed must be above 10 MB/s). Supported file systems are FAT32 and exFAT. The printer only supports mounting one USB drive and cannot connect multiple USB devices via a USB hub.

12. What precautions or recommendations apply to printing with TPU on the H2S?
    Due to the flexible nature of TPU, which can cause issues during feeding and printing, we have created a dedicated wiki guide for TPU printing. Following the guide ensures seamless TPU printing.

13. What precautions should be taken when using the laser function?
    Laser processing involves high-energy beams that can interact with flammable materials. Never leave the machine unattended during laser operation, ensure there are no flammable or explosive objects nearby, and refer to the Laser Safety document for detailed safety instructions.
