A clear water-resistant stereolithography material has passed stringent biological tests and achieved a USP Class VI rating. Watershed XC 11122, developed by DSM Somos (Elgin, IL, USA; www.dsmsomos.com), has been widely used in the medical device industry since it was introduced in 2007, but this new qualification will allow broader biomedical and skin-contact applications for the material.

Because of its functional properties and dimensional stability, the resin has been used to prototype medical device housings and fluid-flow-analysis models. By adding biocompatibility to its portfolio of properties, the material will allow med-tech engineers to produce USP Class VI–approved ABS-like prototypes, according to the company.
