We had a similar need for some designs of our own and tried
reduce it. It does work marginaly; however, we were not
thrilled with the results. The part shrinks from between thirty
to fifty percent non-uniformly, eg certain sections of the part
shrink 30% and some 50%, producing sometimes considerable
distortion of the origional design. Additionaly the surface of
the reduced part is somewhat grainy reqiring attention, either a
PVA coating, sanding, or two generations of molding two a
finished part or some combination of the above.
It is appropriate for some applications but there has got to be
something better. We however are still lookingg as we want to be
able to reduce some parts to ten percent of there original size.
