Porosity is extensively exploited in natural materials as an effective means to reduce weight, minimize resources or enable the transport and storage of fluids and nutrients. Because porosity inevitably reduces the strength of materials, the incorporation of pores should occur with minimum impact on the mechanical performance of the structure. To this end, porous biological materials like plant leaves, animal skulls and bird beaks often exploit porosity gradients at multiple length scales to generate mechanically efficient structures. In this talk, I will present a new processing route for the 3D printing of foams and emulsions into hierarchical and graded porous structures of high mechanical efficiency. Exploiting this concept in engineering applications should lead to the rational utilization of building resources and the minimization of energy demand for transportation without impairing the mechanical stability of the hierarchical structures.
