1. Plenty of CPUs have been built from discrete logic.
2. As soon as you start talking about complex printed items (including PCBs), you're necessitating either a trusted computational device to compile the design and drive the printer, or the ability to audit the output of the printer (eg read and understand the traces on a 2-layer PCB).
