Abstract Scope The broad applications of metastructures in civil and military fields have triggered a lot of investigations on rational design of metastructures, which opens up entirely new possibilities for the manipulation of mechanical properties over a vast spectrum. To envision the unique capability of a level-set based unified computational design and manufacturing framework, we illustrate the potential of using level-set based topology optimization as a systematic and efficient computational design innovation tool to identify the optimal geometry for robust multimaterial and multifunctional mechanical metastructures. Also, in this work topology optimization and additive manufacturing (AM) are seamlessly integrated by exploiting the information embedded in the geometric level set models and conduct mechanical testing to validate the design and modeling methods. The proposed computational framework seamlessly pairs topology optimization technology with additive manufacturing, which will enable the systematic creation of innovative mechanical metastructures without compromise of performances.
