According to use Additive Manufacturing technology in PLA material used Fused Deposition Modeling (FDM) technique. In this project, nine samples are tested for different infill pattern (Zig zag, Triangles & Grid) and different layer thickness (0.2, 0.1 & 0.15) mm by using Taguchi Method. Here we demonstrate an empirical method utilizing a statistical design of experiment technique and standardized mechanical testing which ultimately exposes trends and variable interactions specific to our selected additive manufacturing process. We collect data then converted to stress and strain values in order to construct stress vs. strain diagram and try to use a few basic formulas, mechanical properties such as modulus, yield stress, ultimate tensile stress, and percent elongation were able to be determined for each geometrical infill den...
