David,
I published two years ago in Stuttgart and another in Boston on a paper on
stereolithography process qualification where we presented different test
parts made in different configurations (positions in x and y, orientation
around x and z axis, etc...) and we used a Tagushi approach in order to
minimize the number of test parts. If you are interested, I can send you
the paper jointed to an e-mail.
Regards,
Prof. A. BERNARD
