Mechanical metamaterials are artificially produced structures that derive their properties from their periodically repeated structure rather than from mechanical properties of their base material. Often, these structures are manufactured by 3D printing. Such structures can posses superior properties such as e.g. the negative Poisson’s ratio. These materials exhibit a counter-intuitive behaviour when under the uniaxial tension, the structure expands transversely and vice versa.
Here, the 3D printed metamaterial with negative Poisson ratio is studied.
