Özet
Fused deposition modeling (FDM) is one of the most extensively used additive manufacturing (AM) techniques. This study contributes to the knowledge enhancement related to AM by presenting the details of experimental investigation conducted on FDM of three different materials i.e. polylactic acid (PLA), acrylonitrile butadiene styrene (ABS) and carbon fiber (ePA-CF) and providing the common optimum fabrication parameters for FDM of PLA, ABS and ePA-Cf materials. A detailed analysis of the effect of two important FDM parameters, namely infill pattern (IP) and layer thickness (LT), on mechanical properties of the fabricated samples from the materials, has been done. The best mechanical properties of the PLA sample were obtained with LT of 0.15 mm and hexagon pattern, of the ABS sample were obtained with LT of 0.15 mm and triangle pattern, and of the ePA-CF sample were observed at LT of 0.15 mm and hexagon pattern. It was determined that elongation, yield (YS) and tensile strength (TS) decreased with increasing LT in all materials’ samples. While the fracture surfaces of PLA samples were smooth, and the layer lines were evident. Whereas the fracture surfaces of ABS samples were rough, and the lines were less distinct than PLA. On the other side, the fracture surfaces in ePA-CF samples had a fibrous structure. The voids formed between layers were seen the most in PLA and the least in ePA-CF samples. LT of 0.15 mm and hexagon IP. It was observed that the best results in terms of mechanical properties were obtained under LT of 0.15 mm and IP of hexagon conditions.
