We design, 3D-print and demonstrate the extreme mechanics of architected crystals. Beyond single crystals architected on high symmetry lattices, we're probing the (nonlocal) elasticity, inelasticity and (in) stability of architected polycrystals, inspired by polycrystalline metallurgy and the grain boundary engineering. Through this macroscopic approach for architected crystals, we aim to visualize the intra- and inter-grain mechanisms in their atomic counterparts.

We seek to engineer and leverage microstructural disorder to achieve mechanical, chemical and optical functionalities untapped in architected materials with high internal symmetry and long-range order. Our research aims to elucidate the underlying physical-mathematical principles of "disorder" and the emerging amorphous states of matter. This work is strongly connected to research on Heterogeneous Materials.
