Abstract
The instant invention contemplates a process for manufacturing jewelry including the steps of: (a) creating a photographic negative from a computer-generated image; (b) exposing the back side of a polyester backed soft photopolymerizable resin sheet to ultra-violet radiation thereby causing photopolymerization to a predetermined depth corresponding the exposure duration; (c) masking the negative over a 'soft' photopolymerizable resin; (d) irradiating the unmasked resin with ultraviolet radiation; (e) chemically removing the non-photoset resin from the photopolymer resulting in a positive three-dimensional likeness of the object to be cast; and (f) creating a final negative mold using the positive three-dimensional likeness via a 'lost-wax' type process.
