About the Bambu Lab H2S
Get a large-format 3D printer with a massive 340 x 320 x 340 mm build volume, 1,000 mm/s high-speed printing, pro-level precision, and vibrant multi-colour printing. The H2S is the single-nozzle member of Bambu Lab’s H2 series and has the largest build volume of the Bambu Lab printers we sell. It is sold as the printer alone (Standard), as an AMS Combo with the AMS 2 Pro, or as a Laser Full Combo with the 10W laser module and cutting module.

Laser safety (Laser Full Combo)
The laser module is a Class 4 laser product, and “when the printer’s protection is complete and properly working, the printer and laser module work as a class 1 laser product”, says Bambu Lab. Bambu Lab’s laser safety document says: “This device is not recommended for operation by minors. Please place the device in a location inaccessible to them to prevent accidents.” It also says “When the laser module is working, ensure the area near the device is free from bystanders, children, and pets”, “The laser module stops working if the front door, top glass cover, or safety window is opened” and “Always ensure a person is present to supervise the laser module in operation to promptly address any fire hazard.” Bambu Lab asks that the smoke exhaust system is correctly installed (the Laser Full Combo includes a ventilation pipe) and that materials that could release harmful gases, such as PVC, are not laser engraved or cut.
