Free always sounds good...  still messier than ink jetting around....
And the ink jetting has just been proven out some.

I bet, with just a trace to trace connection overlap area,
using the silver-nitrate/ascorbic-acid ink jet method, you could lay down a "topology layer",
reduce it to silver metal, lay down insulating paint, cure it, prep the overlap areas so
they take new ink jetting conductively, and lay down a second "topology layer" that can
cross over the first, reduce it to silver, cover with insulating mask, cure.

Without any holes at all, you could do multi layers.   Silver's high conductive.  You could do RF.
