ABSTRACT
Lattice structures are low dense, highly porous, and effective in strength-to-weight ratio. Due to these properties, the lattice structures sustain high compressive loads and exhibitbetter mechanical properties. Additive manufacturing facilitates to manufacture the complex lattice structures with fewer material consumptions and gives the necessary strength tothe product. This work analyzes the mechanical behaviour of unit cell-based lattice structures such as “face-centred cubic” and “star” lattice structures. The lattice structures are fabricated through the fused deposition method with polylactic acid material. The mechanical properties calledmodulus of elasticity, and compressive strength and strains are calculated experimentally in X,Y, and Z directions. In a face-centred cubic lattice structure, the experimental and finite element results with a good agreement of 5%, and 48% deviation is observed in the star lattice structure. The results are concluded that the face-centred cubic lattice structure exhibits higher strength compared to the star lattice structure.
