3DMECMET: a package to fill with metamaterials CAD designs and export
them to structural calculation softwares and 3D printable formats.
AbstractMetamaterials are gaining interest with the emergence of the additive
manufacturing technologies. Those implies a capability to perform local
mechanical optimizations of the designs, as well as versatile external
geometries of the components. The software presented is capable to fill
a complex design in a .stl format with a given metamaterial, achieving a
graded stiffness. The software developed is also configured to create
the final design in different formats to perform a virtual test of the
element in a commercial FEM, to edit the design in a CAD software, and
to export it in a 3D printable format.
