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
