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
shrinkages).
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. .................
Don,
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.
