Mechanical Properties and Bioanalytical Characterization for a Novel Non-Toxic Flexible Photopolymer Formulation Class

We present herein a new class of resin formulations for stereolithography, named FlexSL, with a broad bandwidth of tunable mechanical properties. The novel polyether(meth)acrylate based material class has outstanding material characteristics in combination with the advantages of being a biocompatible (meth)acrylate based processing material. FlexSL shows very promising results in several initial biocompatibility tests. This emphasizes its non-toxic behavior in a biomedical environment, caused mainly by the (meth)acrylate based core components. The FlexSL materials are less cytotoxic than other commercial available and tested resin materials. This novel resin material could then be one of the engineering materials of choice for very complex three-dimensional structures in the medical technologies area. A short overview of mechanical and processing properties will be given in the end.Mechanical Engineerin
