Abstract

Additive manufacturing (AM), especially Fused Deposition Modeling (FDM), has emerged as a widely adopted and versatile method for producing three-dimensional components. The process involves the deposition of a thermoplastic filament in a semi-molten state, which solidifies in successive layers to form the final structure. While this method enables the production of complex geometries at relatively low cost, the printed parts often exhibit inferior surface quality and reduced mechanical performance compared to components manufactured by traditional techniques. Such drawbacks are primarily attributed to the layer-wise fabrication process, which may result in poor interlayer adhesion, and anisotropy in mechanical properties.To improve part performance, various studies have investigated the influence of process parameters on mechanical properties using statistical design approaches. Among these, the Taguchi method has been effectively employed to identify significant factors impacting flexural strength. Experimental findings suggest that shell thickness has the most dominant effect on flexural performance, followed by layer thickness, while infill percentage and other process parameters play comparatively minor roles. These results highlight the importance of optimizing shell thickness to enhance structural strength in FDM-printed parts, thereby offering valuable insights for achieving improved reliability and functional application of additively manufactured components.
