Hexastorm is a a project where the goal is to develop a PCB machine which can get an accuracy smaller than 100 micrometers, i.e. 4 mil. The PCB machine should be fast and have a writing speed greater than 1 meter per seconds. This is achieved by using a novel technology, the transparent polygon scanner. The machine uses a transparent instead of a reflective polygon to move a laser beam. The main advantage is that an expensive f-theta lens is not needed and the projection is tele-centric. The current version is shown below.
