Unit cell-based lightweight structure design possesses multiple advantages over the other freeform lightweight geometry design tools. Traditional cellular structure theory focuses on the design of relative density, which provides limited design flexibility and is often insufficient for multi-objective designs. Unit cell design that simplifies the cellular structure into representative unit geometries provides an alternative that addresses the design efficiency issue for structures with complex cellular geometries.
