What is it about?
Can we realize structures that produce any target mechanical behaviors by harnessing both geometric variation and material heterogeneity? Using our multi-material topology optimization approach, multiple materials with different properties are intelligently synthesized into composite structures to achieve arbitrary prescribed responses. We design, analyze, and fabricate these composite structures by multi-material manufacturing, and experimentally validate that their wide-ranging nonlinear responses are physically and accurately realized.

Why is it important?
Creating structures to realize function-oriented mechanical responses is desired for many applications. Yet, the use of a single material phase and heuristics-based designs may fail to attain specific target behaviors. Here, through a deterministic algorithmic procedure, multiple materials with dissimilar properties are intelligently synthesized into composite structures to achieve arbitrary prescribed responses.
