5. Conclusion In the current research paper, the influence of nozzle diameter as a manufacturing parameter in the Fused Deposition Modeling (FDM) process on the mechanical properties and mode I fracture resistance was investigated. The results revealed that a 45/-45 o raster angle increased the plasticity in the tensile sample in all nozzle diameters. Nozzle diameters of 0.8 and 1 mm could increase the ultimate tensile strength compared to the other two nozzle diameters. Also, the highest values of J c belonged to the specimen with raster angles of 45/-45 o and nozzle diameter of 1 mm. These results may arise from the conclusion that as the nozzle diameter was increased the raster diameter was also increased, thus, more exerted loads were needed to fracture the printed samples. Meanwhile selecting an appropriate value for the nozzle diameter depends on the designers’ preferences. Anderson TL. Fracture mechanics: fundamentals and applications. CRC press; 2017. ASTM D638–14.
