Focused microwaves allow 3D printers to fuse circuits onto almost anything

This is a much more promising technique from Applied Science: https://www.youtube.com/watch?v=UIqhpxul_og

The article reads like they are talking about the traces. What about components like surface mount resistors, IC's, etc?

The examples I noticed were things like antennas, grids, a microspring. I didn't see anything resembling a full circuit.

When is this coming to a machine sold by some company to consumers? I really want to make my PCBs at home.

OCTattoos coming soon?
