Make plastic printed circuits with a standard laser cutter

I developed a new chemical process to make double-sided PCBs with a laser cutter, and some common chemicals.  This is intended to be used on SLA 3D-printed parts, but may work on many materials.

  1. Awesome video! Never thought a saturated solution of copper would just deposit like that. I wonder what would happen if you shot a laser beam at an uncharged plastic surface through the copper sulfate solution. I would think the surface would get charged and copper would deposit.. could you then '3D print' something? :P

  2. Just in case you read these. Just watched your hackaday vid, you said you couldn't put electroluminescent coating on non-smooth surface. If you do HOT acetone vapour polishing on an ABS FDM printed part, you will get something pretty smooth. Might be good enough for the coating

  3. Hey Ben! I know this is years old now, but this specific video and a few others have been the inspiration for some of my own work. Thanks!
