This is known as theMaximum Permissible Exposure ("MPE") based on several parameters mentioned here. In a few words there are several materials that (technically) can be cut but should be avoided for different reasons. Lasers can also burn the skin. Its just like with CD and DVD writers. Any performance parameters, geometric tolerances, specific design features, quality and types of materials, or processes should not be inferred to represent what will be delivered by third-party suppliers or manufacturers through Xometrys network. Due to the interlocks built into the laser cutter, however, they are generally sold as Class-1 laser products. The viewing window is optical density 5+ for 10.6 and 9.3 micron laser radiation. This means that they comply with international safety regulations to prevent the user from coming into contact with the dangerous laser. Lasers are divided into 4 classes (and few subclasses) based on their wavelength, maximum output power, and amount of damage they can inflict on exposed people. 2) Level of protection: what protection level is needed is premised on the laser's output.
