Abstract - Mechanical metamaterials draws everyone’s attention and expands its scope due to their exceptionally controllable mechanical properties, along with the advancement in additive manufacturing technology, which facilitates the easy fabrication of the metamaterial. The experimental survey presented in this document involves the design of the hybrid type model (Anti-tetra chiral) and its two variants with modified dimensions, simulation for the designed models for compressive loading conditions using loads 50N, 75N and 100N for each variant of varied dimensions. Inconel 718 material is considered for the simulation study. After simulations, the results obtained are transformed into graphical representation to further analyse the compressive strength that each model can withstand..
