© International Journal of Modern Manufacturing Technologies.Fused deposition modeling (FDM) is a widely used additive manufacturing technique for producing polymeric parts. While most commonly used FDM filaments are PLA and ABS, nylon is a widely used thermoplastic polymer in industry. This study investigated the mechanical properties of FDM-produced specimens made of nylon and quantified the effect of process parameters such as raster orientation and nozzle temperature on the mechanical properties. As the nozzle temperature increases, specimens become stronger with higher elongations at the break. This is mainly due to the improved fusion between the layers, provided by an expansion of the heat-affected zone. On the other hand, specimens with diagonal raster orientation exhibit higher elongations than those with perpendicular and parallel raster. The findings also emphasize the synergistic effects between nozzle temperature and printing orientation, showing that optimization should consider the two parameters together. Overall, FDM can produce strong nylon parts with adequate ductility suitable for load-bearing applications. However, achieving such results requires a detailed optimization of process parameters.
