Influence of Post Curing Conditions on the Mechanical Properties of Stereolithographic Photopolymers
Post cure methods have always been a critical issue for most of the currently used stereolithography photopolymers. Different post cure conditions can be used to enhance the mechanical and physical properties of the stereolithography models. To better understand the influence of post cure conditions on these material properties, an experimental study evaluating various post cure conditions has been conducted. Ultra-violet, thermal and ultra-sound post curing techniques are investigated and a comparative study is made for one epoxy based photopolymer - Somos™ 6100. Similar results should be attainable for other epoxy based photopolymers.
