<title>Stereolithography 1993: epoxy resins, improved accuracy, and investment casting</title>

Abstract

During the past few years there has been much emphasis on the development of stereolithography resins with improved part building characteristics as well as enhanced physical and mechanical properties. A detailed presentation of the results achieved by all four companies would be well beyond the scope of this paper. However, a discussion of a new epoxy resin currently undergoing extensive diagnostic and alpha testing, including experimental data showing a number of extraordinary properties, is both timely and appropriate.
