3D-printing technologies, also known as AM (additive manufacturing), are playing an important role in the fourth industrial revolution. Among the 3D-printing technologies, Fused Deposition Modeling (FDM) is the most popular. FDM is widely employed to produce components by heating, extruding, and depositing filaments of thermoplastic polymers. The properties of FDM-produced parts are significantly influenced using the processing parameters. These processing parameters have conflicting advantages that need to be investigated. In this study, the process parameters' effect on the flexural properties of components produced by the FDM technique is investigated using polylactic acid (PLA). The vertical shell, solid layer top, temperature extruder, infill density, and infill pattern are considered in the investigation. It is observed that only one parameter (infill pattern) significantly influences the flexural properties of the model among the considered parameters.
