dc.description.abstractIn this study, the effect of the notch fabrication method (printing the notch on the part, and machining the notch) on the impact results of 3D-printed polylactic acid (PLA) was investigated. Sensitivity to build orientation was also noted in both test situations. The impact test specimens were printed using an FDM-based printer with or without a notch at various build and print orientations. Un-notched specimens were then machined to create notches. To simulate the impact effects, Ansys software was employed to create a finite element model, and the results of the finite element analysis were consistent with the experimental results. According to the findings, the impact strength of the specimens with 3D-printed notches increased by 11-38% compared to specimens whose notch was machined after the rectangular bars were 3D printed. In addition, it has been observed that the build and print orientations affect the impact strength.en_US
