Abstract
An improved stereolithography method for building a three-dimensional article including the steps of patternwise curing successive layers of a bath of curable liquid resin formulation until the article has been completely built up, removing the article from the liquid resin bath and then post-curing the article, wherein the liquid resin is a "thiol/nene" formulation including: (a) a first compound having a plurality of norbornene groups thereon; (b) a second compound having a plurality of thiol groups therein; and (c) a free radical photoinitiator, the total functionality of the formulation being greater than 4.
