FAQ

1. Does the H2S support laser and cutting functions? It supports 10W laser and cutting but does not support 40W laser. 2. Can a non-laser H2S be upgraded to a laser H2S? Yes. The upgrade kit and its installation guide will be available some time after the product launch. 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 tube. 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 placing an order. 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 can the H2S support, and how many colors can it print? The H2S supports up to 4 AMS 2 Pro and 8 AMS HT units, totaling 12 units with 24 filament slots, enabling up to 24-color printing. 6. Are the hotend and silicone sock of the H2S compatible with the H2D or A1? The H2S hotend and silicone sock are compatible with the H2D. While 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. Using an H2 series hotend on an A1 printer is feasible, but it requires the H2 series silicone sock. 7. Are the H2S and A1 series tool heads the same? Can the components on the tool head be shared with the A1 series? The H2S tool head features a completely new design, with optimized and upgraded components, including the extruder motor, filament drive wheel, hotend heating assembly, and cooling fan. As a result, the components on the H2S tool head are not compatible with the A1 series, except for the cutter blade. 8. Are the build plates of the 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 to the printer via a 6-pin interface. What are the two remaining 4-pin interfaces on the back of the H2S printer used for? The two 4-pin ports on the back are reserved for future expansion accessories. For example, to upgrade a non-laser version of the printer to a laser version, one of these ports can be used to connect an external air pump. 11. Does the H2S come with a standard USB drive, and what functions are affected without one? What are the USB drive specifications? The package does not include a standard USB flash drive. You can still initiate printing normally without a USB, as the printer has built-in storage space to run print files. However, without a USB inserted, the following functions will be affected: 1. The recording and time-lapse photography functions can't be turned on; 2. Printing cannot be initiated through the LAN; 3. Print files cannot be sent to the machine for storage through the Bambu Studio; 4. Log files cannot be exported; USB requirements: USB2.0 protocol or above (actual minimum write speed needs to be greater than 10MB/s), supported file formats are FAT32 and exFAT. and the printer only supports mounting one USB, and cannot connect multiple USB via a USB hub. 12. What precautions or recommendations are there for printing TPU with the H2S? Due to TPU’s flexible nature, which can cause issues during feeding and printing, we’ve created a dedicated wiki guide for TPU printing. Following the guide ensures smooth TPU printing. 13. What precautions should be taken when using the laser function? Laser processing involves high-energy beams that may interact with flammable materials. Never leave the machine unattended during laser operation, ensure no flammable or explosive items are nearby, and refer to the Laser Safety Document for detailed safety guidelines. 1. Vision Encoder: Vision Encoder needs to be purchased separately on the Bambu Lab Store. 2. Auto Hole/Contour Compensation: Auto Hole/Contour Compensation must be enabled in Bambu Studio and requires the use of designated Bambu filaments. 3. Filament grinding detection on the DynaSense Extruder may vary depending on filament type. 4. Filter Mode for low-temperature printing is optional and will be available in Q4 2025. 5. Permanent Magnet Brush-less Servo Motor 6. High Flow Hotend are optional equipment and can be purchased from the official store. 7. When using Bambu Lab PLA Basic to print a 200×200×200 mm cube with 15% infill, the printing time can be reduced by up to 30% compared to Bambu Lab X1C. Actual time savings may vary depending on the model, infill, and filament used. 8. The laser and digital cutting functions are all controlled and visualized through Bambu Suite. Live Spatial Alignment is enabled by the BirdsEye Camera. The BirdsEye Camera comes standard with the H2S Laser Edition, or can be added via the Laser Upgrade Kit. 9. Push notifications require the use of Bambu Handy and cloud connectivity. 10. Due to safety protocol, Developer mode cannot be enabled when using Laser and Cutting functions. 11.
