Abstract
3D printing has emerged as a transformative technology that has revolutionized various industries and unlocked endless possibilities in the world of Research and Development. 3D printing allows the fabrication of three- dimensional parts from computerized designs by utilizing additive manufacturing technologies. Its importance stems from its capacity to expedite prototyping, speed up production, and stimulate innovation in industries including as healthcare, manufacturing and aerospace. The main objective of this study is to analyze the mechanical behavior of 3 dimensional (3D) printed Poly-Lactic Acid (PLA) parts when their infill density and infill geometry are varied. We have taken 3 infill geometries (Grid, Triangle, Gyroid) at 4 different infill densities (40%, 60%, 80%, 100%), these parts are measured for tensile strength and optimal conditions are identified.
