When we talk about laser engraving and cutting of other materials, we are referring to non-ferrous materials, other than metals. For example, plastics, acrylic, methacrylate, wood, cork, rubber, leather, cardboard, etc.
Due to their molecular structure and density, these materials are more “delicate”. Applying excessively concentrated power to them could damage them.
For these cases the CO2 laser system is available.
CO2 laser system
The CO2 laser works with a wavelength between 9.4 and 10.6 µm (microns). That is, about 10 times more than the fiber laser. So the point of impact is higher. Thus, the power is diffused in a larger area, without being so aggressive for the piece.
Therefore, this system allows you to engrave and cut materials that are “softer” than metals, without damaging them. Materials such as those indicated above: plastics, acrylic, methacrylate, wood, cork, rubber, leather, cardboard, etc.
Note that, in the case of engraving, it can be given the necessary height, both in negative (the engraved drawing remains inside) and positive (the engraved drawing remains in relief). As well as how to make a superficial engraving (marking).
