In rapid prototyping (RP), 3D printing is growing fast due to its ability to build different complex geometrical shapes and structures in the least possible time. In this manufacturing process, a computer-aided design (CAD) model is used to fabricate a physical model. The prototype is made by deposition of material in layer by layer. The major advantage of this manufacturing process is that it can fabricate complex parts quickly with minimum loss of material. There are many rapid prototyping techniques available commercially. Fused deposition modeling (FDM) is one of the most widely used methods. The mechanical behavior of 3D printed fabricated PLA parts depends on the interaction of different process parameters and the raw material properties. In this work, the effect of process parameters, namely layer thickness, Volume Infill, and print speed, has been studied on mechanical properties like tensile strength. It was observed that tensile strength increased with an increase of volume infill, minimizing print speed and layer thickness. The experimental results are compared with the simulated results from ANSYS.
