For those with an interest in this subject. I will be presenting a white
paper at the Santa Fe Symposium on Jewelry Manufacturing on May 22-23,
2005 in review of the following : 3D Systems Viper, 3D Systems Invision
HR, Solidscape T66, and EnvisionTEC Perfactory Mini, RP systems as they
apply to the investment casting process.

Revolution of CAD/CAM in the Casting of Fine Jewelry

CAD/CAM technologies, used with the casting process, have been a great
challenge as jewelry manufacturers increasingly bring these new methods
of design and materials into daily production arenas. This paper
compares the advantages of different additive fabrication manufacturing
methods, generally termed Rapid Prototyping (RP), and focuses on new
machine technologies available for producing jewelry-quality models. In
addition, materials and techniques, shrinkage rates, thermal expansion,
burnout parameters and surface treatments must all be considered
differently when comparing RP manufacturing methods with traditional wax
model casting. Finally, techniques that allow direct casting of
photopolymer resins will be explored.
