The work consisted of adapting and developing the process parameters of FFF to produce tensile specimens. These parameters included the infill pattern, density, printing angle and support structures. In addition, several tests were done, like tensile, surface roughness, and microscopic analysis, to validate the imposed parameters. After gathering the best parameters, a part from the automotive industry was printed to optimise the parameters, and cost analysis was compared with SLM technology. Thus, in this dissertation, the process parameter optimization of the FFF technology was made.engFused Filament FabricationAdditive ManufacturingStainless SteelInfillSupport Structuresmaster thesis203173341
