Özet

In this study, the changes in the mechanical properties of parts produced using the fused deposition modeling (FDM) method were investigated according to the printing speed of a three-dimensional (3D) printer. For this purpose, tensile test specimens were prepared using poly-lactic acid (PLA) material on an Ender 3 S1 Pro 3D printer, with printing speeds ranging from 15 mm/s to 105 mm/s in 15 mm/s increments and at 100% infill rates. In the research, the masses, hardness values, and surface roughness of the samples were measured in detail to determine the potential effects of printing speed on the mechanical properties of PLA. Additionally, porosity values were calculated to determine the homogeneity of the samples' internal structure and void ratios. The obtained results demonstrate that changes in printing speed lead to significant alterations in the production quality and strength performance of the samples. The findings of this research indicate that 3D printing speed can play a decisive role in the mechanical properties of the material.
