Design and Simulation of Metamaterial Structures for FDM Applications

Metamaterials have gained significant attention from researchers across various fields due to their unique properties. Unlike conventional materials, which exhibit a positive Poisson ratio and become thinner when stretched, metamaterials possess a negative Poisson ratio. This characteristic offers advantages in applications such as energy absorption, sensing, and medical implants. This research specifically centers on the design and simulation of metamaterials for fused deposition modeling (FDM) applications, with a primary focus on investigating the effects of infill density and pattern on metamaterial behavior. 3D ASTM Type IV dog bone structures were designed, and finite element analysis was employed to explore the mechanical properties of metamaterials featuring different infill patterns and infill densities.
