The skins of armadillo, alligator, snakes or fish display unique and attractive combinations of resistance to penetration, flexibility and light weight. These armors are made of stiff and hard plates of finite size (tiles or scales) embedded in soft tissues. Resistance to puncture and compliance are controlled by the relative motion of the scales or bony plates and therefore by their architecture, which includes their shape, size and arrangement. In this talk we will discuss how we use 3D printing to explore how the architecture of stiff protective plates on soft substrates can be tailored to achieve a wide range of properties. In particular, we will discuss the tilt stability of individual plates, the redistribution of strains, the overlapping between the plates and interlocking mechanisms between the plates. We explored these features and mechanisms using geometries inspired from teleost and ganoid scales, as well as from modern topologically interlocked materials.
