Abstract :This study focuses on investigating the effect of process parameters on the tensile strength of PLA and iron-reinforced PLA samples produced using FDM technology. Filament material insert ignore into journalissuearticles values(PLA and iron-reinforced PLA);, infill ratio insert ignore into journalissuearticles values(20, 40 and 60%);, layer thickness insert ignore into journalissuearticles values(0.1, 0.2 and 0.3 mm);, printing speed insert ignore into journalissuearticles values(40, 60 and 80 mm/s); and raster angle insert ignore into journalissuearticles values(30, 45 and 60°); were selected as process parameters. The experimental design was based on the Taguchi L18 index. Signal-to-Noise insert ignore into journalissuearticles values(S/N); ratio, variance analysis insert ignore into journalissuearticles values(Anova); and regression analyses were used to statistically analyze the tensile strength values obtained as a result of experimental measurements. The outcomes of this study show that the filament material plays an important role in tensile strength and iron reinforcement to PLA material decreases the tensile strength and increases the % elongation. The maximum tensile strength was measured as 33.55 MPa at 60% infill rate, 0.3 mm layer thickness, 60 mm/s printing speed and 60° raster angle in PLA filament material, which is the optimum process parameters.
