Abstract

Porous and microporous parts prepared by additive manufacturing as disclosed herein are useful in medical and non-medical applications. The parts are prepared from a composition containing both a solvent soluble component and a solvent insoluble component. After a part is printed by an additive manufacturing process it is exposed to solvent to extract solvent soluble component away front the printed part, resulting in a part having surface cavities.
