We are working on a software based technology that effectively adds
non-uniform shrinkages. In essence:
 - we make a part with the normal shrinkages,
 - measure the resulting shape,
 - feed this into a software program that calculates the shape that
     should be fed to the RP machine to make a better part (without

If you are interested, send me an Email and I'll send you more info.

Yes, Erkut. That is indeed the biggest problem. We have software that=20
adds shrinkage factors automatically, but of course complex geometries=20
don't shrink equally. .................


Is the software commercially available? Could you give us more info. on =
how it works Also, do you have any data/literature on the effect of part =
geometry/mass on shrinkage? Thank you.
