Nature benefits from high stiffness and strength low-weight materials by involving architected cellular structures. For example, trabecular bone, beaks and bones of birds, plant parenchyma, and sponge optimize superior mechanical properties at low density by implementing a highly porous, complex architected cellular core [25]. The same engineering and architectural principles at the material scale have been used by humankind to develop materials with higher mechanical efficiency and lower mass in many weight-critical applications. The emergence of advanced manufacturing technologies such as additive manufacturing and three-dimensional (3D) laser lithography offer the opportunity to fabricate ultralight metallic and composite materials with intricate...
