The Hasso Plattner Institute HCI Lab showcases their Metamaterial Mechanisms, 3D-printed objects that, thanks to their 3D cell grids composition, can perform controlled directional movement despite being a single object.

So far, metamaterials were understood as materials—we want to think of them as machines.

We push the concept of metamaterials 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.

We demonstrate metamaterial objects that perform a mechanical function. Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch.
