Scalable Design for Manufacturing, Modeling Optimization for Additive Manufacturing

The Navy seeks a framework for generating scalable lattice structures which can be utilized for developing new structural components that are lighter yet achieve improved structural performance. Corvids design approach will utilize topology optimization to generate an initial distribution of material in the component design. Using the material distribution obtained for the topology optimized component, lattice with same corresponding mechanical properties will be seeded into the computational domain. In order to bridge the multiple scales of the lattice structures, a second round of topology optimization will be performed only at the boundary of the lattice unit cells. This will yield a continuous internal structure utilizing multiple scales of lattice structures to achieve both structural and mass efficiency.
