We made a video how to make a printed circuit boards using diode laser installed on a 3D printer (or you can put on any CNC mill)

The idea is that you cover copper board with a vinyl film and then remove it with a diode laser.
The simply put into Ferrum chloride.
If anyone has an idea how to make edges more accurate, please let us know.
