Hexastorm develops desktop PCB prototype equipment with a laser scanner and a spindle. It already developed the transparent polygon scanner, which can get an accuracy smaller than 100 micrometers, i.e. 4 mil, without an f-theta lens. The technology to cut boards with a spindle is under development. A video of the scanner can be seen on Youtube . A blog with recent progress and technical details can be found at Hackaday.
