- The development of surface-based mechanical metamaterials has been potentialized by additive manufacturing and parametrization techniques. Herein, novel surface-based metamaterials inspired by the gyroid minimal surface are designed, tailoring their mechanical properties by a finer degree using a parametrization based on cubic-based Bézier curves. The use of such curves allows the user to customize the constituent surface at a higher detailed level. This new parametrization presented allows for a fine tuning of the mechanical properties of surface-based metamaterials. This methodology can tune the stress¿strain response and the corresponding effective properties. The effective stiffness of the metamaterials designed can be adjusted within a ±15% range compared to the original gyroid structure. The length of the plateau can be tuned up to a 55% of the total strain applied. Hence, the use of the parametrization presented can benefit the design of mechanical metamaterials with tailored properties for energy absorption applications. © 2025 The Author(s).
