Lattice Block Material{trademark}, or LBM{trademark} is a unique lightweight structure consisting of repeated cells with an internal node connected to, in the most common configuration, 14 ligaments. In its metallic version, this product is available in a variety of castable metals including aluminum alloys, copper alloys, nickel alloys and steels. The relationship between LBM structural performance (strength and stiffness) and parent metal properties is investigated using compression tests in three primary orientations and 3-pt. bend tests. Analytical assessment of the LBM via finite element analysis shows reasonable agreement with experimental findings and provides predictions for LBM capabilities with different materials, unit cell sizes and ligament geometries.
