We made a few experiments with casting parts by using a UV Curable SOMOS
resin in a mold made of Reynolds Sorta Clear silicone. The process appears to
work reasonably well when we use sunlight to provide the UV energy.

This may sound like an expensive way to make a casting, but it has several
advantages if you are trying to reconstruct a master pattern from a mold.

We were wondering if anyone on the list has tried a similar process?


Hi Doug:
This is a fairly common process and is often called "optical molding" or
variations on that theme. It seems to be used pretty often for high-value items
such as contact lenses, and at least in the patent literature, Japanese
companies are frequent practitioners.
