吴俊 | Recent Advances in Topology Optimization for Additive Manufacturing

Additive manufacturing enables the cost-effective production of highly complex geometries, expanding the design space beyond traditional limits. To navigate this expanded space, topology optimization has become a powerful and essential tool. In this talk, I will present recent advances in topology optimization for AM applications. I will begin with multiscale topology optimization - particularly de-homogenization techniques - which enable the efficient generation of lattice infill structures. The discussion will then shift to manufacturability, traditionally addressed through geometric design rules. I will highlight our recent work on space-time topology optimization, a novel approach that simultaneously optimizes both structural design and the fabrication sequence.
