Multiscale 3D Printing System for Fabrication of Next Generation Multiscale Architectured Armor Materials

Abstract

The original goal of the proposal was to develop multiscale additive manufacturing (AM) through acquisition of state-of-the-art light-based digital light synthesisTM (DLS) (Carbon (registered trademark) M1 3D Printer) and layer-by-layer (Stratasys J735TM) 3D printing equipment that will provide unprecedented capability to design and fabricate novel architectured materials with multiscale resolution. Since the agency approved the purchase of a layer-by-layer 3D printer, the revised major goal is to design and fabricate novel heterogeneous architectured materials at the meso-scale to activate multiple damage/failure mechanisms as a driver for enhanced ballistic performance. Architectured materials constitute merger of structure and material. Together with existing high performance computational and dynamic impact testing facilities in our department (shared memory cluster, high speed cameras, split Hopkinson pressure bar, shock tube, drop-impact tower), the specific goal is to investigate processing-structure-property relationships of additively manufactured architectured composites materials. This research will enable rapid design of emerging game change materials with spatially tunable superior impact-resistant properties for defense applications; and enable design of high-throughput additive manufacturing process for development of materials for extreme conditions.
