Evaluation of Biocompatible Photopolymers II:Further Reactive Diluents

摘要

Within these investigations a new monomer formulation-consisting of a biodegradable basis monomer,reactive diluents,fillers,and an appropriate photoinitiator-was developed for the stereolithographic fabrication of bone replacement materials.In the current paper we describe the testing of several acrylate based reactive diluents-having different functional groups-concerning reactivity,biocom-patibility,and mechanical properties.Polymers from tripro-pylene glycol diacrylate,propoxylated glycerol diacrylate and tricyclodecan dimethanol diacrylate showed the most promising results regarding these 3 criteria.Three-dimensional spongiosa-like structures were built by stereolithography using different monomers,fillers,and a suitable photoinitiator.
