Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being compressed. The plant’s hardiness comes from a combination of its hollow, tubular macrostructure and porous, or cellular, microstructure. These architectural features work together to give grass its robust mechanical properties. Harvard SEAS, Wyss Institute and MIT have developed a new method to 3D print materials with independently tunable macro-and microscale porosity using a ceramic foam ink...
