This area can be used to clean metal things gently. So if you have something that you want to remove the rust or paint from without removing any of the underlying metal (like a sandblaster would), this tool could be useful for that.
Many plastic recyclables in our area lack a stamp indicating the type of plastic used to create the object. This device would allow these items - including a significant % of caps/lids, to be sorted and recycled using the Precious Plastic machines: https://matoha.com/shop/plastell-desktop-18#attr=
A 3D scanner would be a very useful tool in developing designs for the 3D printers. I believe that it could be useful in designing for the CNC machines as well.
