Topology Optimization

Definition

Topology optimization is a computational design process that aims to optimize material layout within a given design space to achieve the best performance according to specific constraints and loads. It is closely linked to additive manufacturing because it allows for the creation of complex geometries that can enhance structural integrity and minimize material usage, aligning with biomimicry principles that draw inspiration from nature's efficient designs.
