3D Printed Mechanical Metamaterials Beyond Classical Continuum Mechanics – Presented by Tobias Frenzel, Karlsruhe Institute of Technology at the 3D Printing Materials Conference which will take place on 2 February 2017 at Brightlands Chemelot Campus in Sittard-Geleen, The Netherlands.

In 3D printing, the number of printable materials is limited and therefore also the accessible physical properties like stiffness, energy absorption, or density are limited. Metamaterials can  overcome these restrictions by exploiting structure.

Absorption of mechanical shocks is usually based on viscoelasticity or destruction of the material. Using the buckling instability of inner elements, a different type of absorber has been realized leading to a self-recoverable and reusable metamaterial.

Furthermore, we present structures that break centrosymmetry leading to coupling between rotation and axial compression which might enable for new cloaking devices for mechanical waves.
