Abstract
Additive manufacturing (AM) has been highly popular in recent years and the number of scientific efforts on this useful manufacturing way has increased day by day. Up to now, the majority of the studies accumulated on the physical and mechanical properties of the three-dimensional (3D) printed specimens. In this paper, the impact properties of the additively manufactured polylactic acid (PLA) parts were addressed in detail. All specimens were manufactured by way of fused deposition modeling (FDM). After the manufacturing, hardness and surface roughness measurements were carried out to probe the effectiveness of the offered FDM technique. In order to detect impact features of the PLA specimens, Charpy v-notch impact tests were conducted and the influence of the notch angle was examined. As for the manufacturing parameters, the factor of infill density was altered and its effects on the impact behaviors of the specimens were established. Furthermore, micro and macro damage analyses were performed elaboratively on tested PLA specimens to comprehend the main mechanism of deformation better.
