## Description

- description: An auxetic metamaterial is a type of mechanical metamaterial that has
    negative Poisson's ratio. Most auxetic metamaterials are truss-based or originate
    from Boolean operations of simple geometries. Herein, we introduce a new 3D auxetic
    metamaterial that is mathematically generated from an implicit expression. Further,
    this metamaterial is fabricated by 3D printing using a flexible material, which
    allows it to recover from large deformations. The buckling-induced auxetic behavior
    of the metamaterial was evaluated via compression tests and finite element analyses.
    A nickel layer was then plated on the surface to enhance its stiffness, strength,
    and conductivity without loss of auxeticity and resilience. The integration of
    3D printing and electroless plating thus enables accurate control over the mechanical
    and conduction properties of the auxetic metamaterial; these properties are presented
    as contour maps for guidance in functional applications.
