How you are counting this? Volume, proportion of mechanical parts, proportion of total number of parts, number of compounds, number of elements? By any measure I can think of
the machine makes a small fraction of what is needed to make another machine - especially considering the electronics and metal rods. Fractions of the collective energies of hundreds of thousands of people are required in the electronic components, motor and plastics manufacturing industries for the rest. For me the "self-replication" aspect is an interesting dream worth thinking about and perhaps striving towards (as reflected in the various challenges). This doesn't detract at all from the considerable contributions to low cost 3D printing represented by the work around reprap.
