Researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials are artificial structures with mechanical properties that are defined by their usually repetitive cell patterns, rather than the material they are made of.So far, metamaterials were understood as materials but you can think of them also as machines.
The concept of metamaterials is pushed further by creating objects that allow for controlled directional movement. This allows users to create objects that perform mechanical functions. Our objects thereby implement devices that transform input forces and movement into a desired set of output forces and movement—also known as mechanisms.
