What strikes me is that we are reaching "mass manufacturing" limits (or possibly internal combustion engine limits. Possibly both. I have a nice modern car, and it stopped working the other day. And I had absolutely no idea what was wrong. No way to diagnose and no conceptual framework. Military hardware (I am guessing) cannot be as fragile as my nice car, so it must now be lagging behind the cost benefit curve of commercial car production - all the efficiency gains Ford makes must get lost as they cannot risk the fragility. Additionally military hardware is really a special snowflake - lots of highly specific not really available commercially parts. So military hardware must be desperate for actually working 3d printing / one off manufacturing - it solves the cost problem and the special snowflake problem. So I am guessing the DoD will be a heavy investor in all things additive manufacturing for a decade ? Am Inway off base ?
