State-of-the-Art Filament Monitoring

15 sensors on one filament path

Unlike legacy systems with a single filament jam detector, H2D features comprehensive material flow monitoring. Along the entire AMS-to-die path, 15 strategically placed sensors form an intelligent network that continuously monitors five key parameters: feed rate, filament tension, filament tip position, extruder thermal environment, and dynamic extrusion pressure. This creates an industry-leading system for controlling filament behavior.

FAQ - Frequently Asked Questions

1. Can the H2D be upgraded to the H2D Laser Edition?

The H2D Laser Full Combo has a built-in air pump and air hose on the back of the printer and is pre-installed with a BirdsEye camera. The front door, left and right laser safety windows, and top cover are all designed with laser safety in mind. The package includes a laser module, a cutting module, a fume extraction hose with adapter, and an emergency stop button.

We plan to launch a laser upgrade kit for the non-laser H2D. The upgrade kit is expected to be released in Q3 and will also include installation videos to help users complete the upgrade smoothly.

It is important to note that the air pump in the upgrade kit is an external pump, which has a different installation structure than the built-in pump in the full combo kit. It can only be mounted externally and connected to the machine via an air hose.

Upgrading the H2D without laser to the H2D Laser Edition via the upgrade kit retains identical product features and performance as the H2D Laser Edition.

2. Are the left and right hotends completely identical?
Yes, the left and right hotends have identical structure and materials and can be used interchangeably.

3. What is the maximum number of AMS 2 Pro and AMS HT devices that H2D supports? How many colors can it print at most?
Since the H2D is a dual-hotend printer, and in the most extreme case, all AMS devices can be connected to one hotend, while the other hotend uses an external spool holder, it can support up to 25 colors.

4. Is H2D compatible with the first generation of AMS?
The first generation of AMS is fully plug-and-play compatible and can be used with H2D for multi-color printing, but it does not support the AMS drying function.
Due to fundamental differences in feeding mechanism and buffer structure, H2D does not support AMS Lite.

5. The AMS 2 Pro connects directly to the printer via the 6-pin ports – what are the two 4-pin ports on the back of the printer 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 a non-laser version of the printer to a laser version.

6. Can I use the A1 series hotend on the H2D? Conversely, can H2D hotends be used on A1 printers?
Although the H2D hot end is structurally similar to the A1 hot end, it is not entirely identical.
H2D hotends are specifically designed for the H2D printer and offer optimized compatibility, such as supporting higher maximum volumetric flow, lower risk of clogging, more accurate nozzle offset calibration between the left and right hotends, and automatic hotend recognition via the live camera.

To ensure optimal print quality, it is strongly recommended not to use A1 hotends on H2D printers.

It is possible to purchase additional H2D hotends for use on A1 printers, but you must also use the H2D hotend silicone sock.

7. What are the differences between the 10W and 40W laser modules? How should I choose?

Both the 10W and 40W laser modules are blue light lasers that support processing a variety of materials including wood, rubber, sheet metal, leather, dark acrylic, and stone. However, due to differences in power and size, there are the following differences:

1. Maximum cutting depth (for Basswood plywood):

• 10W laser: 5mm

• 40W laser: 10mm

2. Maximum digging speed (for Basswood plywood):

• 10W laser: 400 mm/s

• 40W laser: 1000 mm/s

3. Processing area:

• 10W laser: Max. area X310 mm × Y270 mm, max. height 280 mm

• 40W laser: Max. area X310 mm × Y250 mm, max. height 265 mm

The choice depends on your needs: for faster cutting, engraving on thicker materials or higher production speed, the 40W module is best; for smaller requirements and economical operation, the 10W module may be sufficient.

8. Is a USB included as standard? What functions are affected without USB?

The package does not include a standard USB flash drive. You can still start printing normally without USB as the printer has built-in storage to run print files.

However, without USB, the following functions will be affected:

1. The recording and time-lapse functions cannot be activated;

2. Printing cannot be started via LAN;

3. Print files cannot be sent to the machine for storage through Bambu Studio;

4. Log files cannot be exported.

USB requirements:

• USB 2.0 protocol or higher (actual minimum write speed must be above 10 MB/s)

• Supported file systems: FAT32 and exFAT

• The printer supports only one USB port at a time and cannot connect multiple USB devices through a USB hub.

9. Why can't I freely choose the hotend for printing with the printer's built-in files?
The hotend to be used for printing is already determined when the model file is sliced. For the built-in models, the right hotend is selected during the slicing process, so it is not possible to change which hotend is used for printing directly on the printer screen.

When slicing the file in Bambu Studio and sending the print job, you are free to choose to use the left or right hotend. For certain filaments, such as TPU and PPS/PPA-CF, it is recommended to use specific hotends for printing.

10. Will smoke and dust from laser operations affect the printer's precision and lifespan?
The H2D is equipped with an efficient extraction system that effectively removes smoke and dust from laser work and significantly reduces contamination. During R&D, we have conducted extensive tests that show that with regular cleaning, smoke and dust have minimal impact on precision and performance. For detailed cleaning instructions, see the Wiki .

11. How can I improve the success rate and quality of TPU printing?
Due to the flexible nature of TPU filaments, challenges can arise during feeding and printing. To facilitate TPU printing, we have created a dedicated guide in the Wiki . Simply follow the instructions to achieve successful TPU printing.

12. Are there any special safety precautions when using the laser function?
Laser processing uses high-energy lasers on potentially flammable materials, so we strongly recommend that users do not leave the machine unattended during laser operations. Ensure constant monitoring of the machine's status and remove all flammable or explosive materials from the surrounding area. For more information, see the Wiki .
