Hard to disagree with that.
One naturally wonders if 3D printing technology will progress to a level where complex semiconductor circuitry can be created.
Getting to the fractional micron dimensions of current microelectronics would seem to be problematic . But maybe not. And perhaps less fine geometries will become practical. Custom microcircuits Built in your own bedroom - what a concept.
The very small structures that are currently obtained using extreme UV are reaching the limit of what physics will allow the circuits to do reliably and consistently. But I can see where a VLSI type application could be tested if the proper materials can be made available in a manner consistent with 3D printing. It is doable but may be a year or so away ) assuming anyone is working on it——and it wouldn’t surprise me to hear that some university or R&D group are doing just that). Field Programmable arrays and chips may be some of the first devices done in such a manner.
