I've been digging the SL4 archives, and found that thread (among many

As far as I know, standard engineering (techniques used today in mass
production of micro-anything) is pretty far from that, mainly due to
nanoscale-specific obstacles (surface effects, short-range forces,
quantic effects...); on the other hand a great effort (meaning many $)
is being put both on new specific techniques (self-assembling stuff,
quantum dots, nanotubes...) and in more basic investigation of the
nanoscale physics, so in order to conquer the world it would be wise to
wait for a few years, until you can set free your own basement-made
nanothings. Even then, I think that the idea of a really universal
fabrication utility is quite optimistic.
