Title: STABILIZED ADDITIVE MANUFACTURING ARTICLES
Abstract:
An additive article stabilizing method includes prior to polymerization, adding a radiation-activated stabilizing composition to a liquid resin, forming the article from the liquid resin, layer by layer, using radiation such that the stabilizing composition does not stabilize the liquid resin but the formed article, and neutralizing free radicals generated during a degradation process initiated by exposure of the article to additional radiation post-cure.
