Title: Topology Optimization of Multiscale Structures for 3D Printing
Abstract: 3D printing enables the fabrication of complex structures. In engineering the benefits of this manufacturing flexibility are probably best demonstrated in combination with the design of structures by topology optimization. In this talk I will present our research on topology optimization of multiscale structures. The first approach, inspired by trabecular bone, generates porous bone-like infill structures for 3D printing. This approach is extended to allow simultaneous optimization of shape boundaries and the interior lattice. To reduce its computational complexity, a homogenization-based approach is developed to project orthotropic lattice structures. In the second approach, we develop a continuous formulation to the discrete problem of quadtree subdivision. By restricting the subdivision level, geometric features such as maximum and minimum structure sizes can be controlled, for manufacturing benefits.
Images of optimized structures and fabrication results can be found on this page.
