I also am satisfied with what the pcb industry provides anyways, but couldn't this 3d printing technique produce more than 2 layer boards? That seems like at least one potential improvement beyond milling a copper board. I do wonder how well the non-conductive material handles the heat of soldering though. I think it could be cool to combine the circuit board and enclosure into one thing, even though that's terrible for serviceability.
