I believe that Ed Garguilo's report included an CNC'ed user part out of
Aluminum. I'll hunt around for the paper and see if I can find it. The
initial study was WAY back in the early 90s and using the ole 5180 stuff.
This study has not been repeated using any of the newer resins. As far as
relative to several RP processes... the standard user part was 9.5x9.5x 1.5
so it would not fit in some machines..also I think that maybe 2 machines
were commercial when the first report was done. Heavens do I feel old.

Opinions, suggestions, and other controversial matter VOID where prohibited.
