Abstract Applications for the MSOE TetraLattice (TM) used for SFF structures are growing. The simplicity of the tetragonal lattice morphology makes this structure useful for composite and metal castings, gradient morphologies, conformal cooling and heating systems, transfer and filtering systems, rapid build style, and stress-reducing build style. As more applications emerge, the need for a simplified 3D CAD representation, with easily adjustable void-solid ratios, has become increasingly important. The volume was determined as a function of node spacing and node size in a simplified, minimal surface representation. Reducing the points required to define the lattice surface is key in reducing processing time and improving synthesis quality. The simplified CAD representation and mathematical model, used to determine percent volume, will be presented followed by TetraLattice applications. (Auth abstract) [References: 8]
