The Snapmaker 2.0 A350 enclosure is constructed with aircraft grade aluminum alloy and laser filtering acrylic sheet. It is super easy to assemble as the doors is already pre-assembled. The enclosure can protects from potential hazards caused by the laser engraving/cutting process. When one of the doors is opened, the laser engraving/cutting process will stop automatically; when all the doors are closed, you can resume the laser engraving/cutting via the touchscreen. The enclosure uses a folding door mechanism and takes up less space, reducing the risk of breaking the acrylic panels.
