The high strength and low weight requirements of advanced land, air and sea vehicles are obtained by taking advantage of sandwich panel structures. The low density cores used are limited to feasible topologies by current manufacturing techniques. Fused deposition modeling combined with electroforming removes the manufacturing limitations and creates topologies with comparable mechanical properties to conventional cores. Tetrahedral, pyramidal and ' strut-reinforced tetrahedral (SET) unit cell topologies will be optimized for specific strength. The response of fused deposition acrylonitrile butadiene styrene (ABS) plastic cores will be presented. In addition, scaling experiments such as 3D scaling and slenderness ratio scaling will be conducted on a unit cell analysis.
