Production of a printed circuit boards, using diode laser installed on a 3D printer.

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.

Hi.

Unfortunately, we do not know of a good way to get more accurate edges with your process. However, I did notice that you mentioned using vinyl film as a masking material. Vinyl, also called PVC, contains chlorine, so laser cutting it releases chlorine gas, which is very toxic.
