Dear List,

Please help me..
I am not an expert in RP, just a student in research of the evolution
of new technology in industries and its implication.
I got a problem.
I asked Terry Wohlers about my research assumption.

"RP is superior to CNC in the small batch production of complex
figure, and aerospace industry is just the case. Currently, investment
casting which used frequently in aerospace production is helping
percolation of RP in the field. In addition, SLS is fit for the
production of composite material parts. CALS is infrastructure.
Therefore, RP in aerospace can reach higher level(or faster) than that
of automobile."- I think that the object of RP in auto is not the
production of final goods(componets). But I suppose, it is in

Terry's reply is ...RP in automobile is every bit more advanced than
in aero.
I am so frustrated, I don't know from where I went wrong in the
assumption. (might be because the internal market for the unit
production of automobile mould is so large..)
Even I don't know whether RP in auto is identical with that of aero.
Please give me an advice so that I can find right direction.
