Abstract
A system and method for making a biomaterial device includes a support structure providing a shape for a biomaterial device. At least one applicator has a supply of biomaterial solution and is positioned along the support structure. The at least one applicator forms a biomaterial fiber by applying shear force to the biomaterial solution and delivering the biomaterial fiber to the support structure. A controller causes relative movement between the support structure and the at least one applicator, and the biomaterial fiber is arranged on the support structure according to the relative movement to form the biomaterial device. The biomaterial may be silk fibroin which may be wound onto a reciprocating and rotating mandrel. Control over the properties of the biomaterial device is achieved through appropriate selection of material processing, winding strategy, and post-winding processing.
