Re: 208 B transistors !!

 I guess, if one could get it to run at MHz speeds, this could be enough for a CPU.

Though, would likely need multiple passes through the printer to print something like this, say:
   Print transistor layers;
   Bake the sheet;
   Print insulator and metal trace layers;
   Bake;
   Print more insulator and metal trace layers;
   Bake;
