| description | This study investigates the mechanical behavior of 3D-printed polyethylene terephthalate glycol (PETG) polymer specimens subjected to tensile and shear testing, with a particular focus on the influence of raster orientation and shell contour. Specimens were fabricated using Fused Deposition Modeling (FDM) at three raster angles (0�, 45�, and 90�) and tested using both a mechanical extensometer and a Digital Image Correlation (DIC) system. The results indicate a significant influence of raster orientation on tensile and shear properties. 0� specimens exhibited the highest tensile strength, as the filament alignment was parallel to the loading direction. In contrast, 45� specimens demonstrated more ductile behavior. While the shell contour had minimal effect on 0� and 45� specimens, it enhanced stiffness and ductility in 90� specimens. Furthermore, the Tsai-Hill criterion was applied to predict the tensile strength at a 45� orientation. These findings contribute to a deeper understanding of the anisotropic behavior of 3D-printed materials and highlight the importance of raster orientation in optimizing mechanical performance. |
