Making these flexible boards is an arduous process and requires a LOT of
capital outlay, so you have to make a LOT of boards or they will be
very expensive.

Maybe true if they're made of mylar or kapton, which most are, but I already
posted that very thin FR4 exists, and can be processed in exactly the same
way as any other copper clad FR4, and possibly it may even accept laser-
printed toner directly on to it, as it will roll just fine through the
printer. I don't know where to buy it, but I was given some by a guy who
would not have done that it it was particularly expensive or hard to come by.

Reread the article, this is NOT how he is making boards.

He is basically cutting the conductors from copper foil, laying the
foil on the printer, then printing the plastic on top of it.

The plastic is whatever the printer prints.
