Abstract
A method for producing a prototype of an article includes generating a data file utilizing a computer aided design apparatus to provide data representing all of the geometry and contours for the inner cavity of the mold required to mold the article, using the data file to create the mold as a physical object directly from photosensitive resin utilizing a stereolithographic apparatus whereby the mold which is created utilizing the stereolithographic apparatus has a mold cavity having the geometry and contours required to blow mold the prototype of the article, positioning the mold in the blow molding apparatus, introducing a preform into the mold; and expanding the preform against the surface of the inner cavity of the mold to produce the prototype of the article.
