Once we can make materials that are smooth, and precise enough to be used as bearings, and once we can print semiconductors we will have little actual need for centralized manufacturing, other than for efficiency, or convenience.
Already 3d printed cellulose has been done; no more stockpiling toiletpaper for TEOTWAWKI!
