WHY
This project is the result of an exploration of metamaterials design opportunities. Metamaterials are artificial structures whose mechanical properties are defined by their typically repetitive cell patterns, independently of the material used (as long as it has a desired deformation behavior).

WHAT
Metahinge is a hinge realized in a metamaterial that enables the movement of a swing chair. Compared to traditional hinges, it does not require lubrication. The prototype was made with 3D-printed TPU, but a final product could be made from a much more durable material and using more convenient production processes, such as injection moulding.

HOW
For this project, two main types of cells have been used: Shear Cells and Rigid Cells. Shear Cells represent flexible points in the system, while Rigid Cells are the rigid points. By combining these two types of cells, it is possible to create complex assemblies that integrate their mechanical characteristics to produce the behavior of a macroscopic object.
