| contents | This research addresses a critical gap in the understanding of Fused Deposition Modeling (FDM) by investigating the effects of hybrid infill configurations on the mechanical performance of Polylactic Acid (PLA) components. While the influence of individual infill patterns and densities on structural properties is well-documented, the synergistic effects of combining multiple pattern layers within a single part remain underexplored. This study systematically analyzes the tensile and flexural behavior of ASTM D638 Type-I and ASTM D790 specimens, respectively, fabricated with varying combinations of honeycomb, grid, and triangular infill patterns at 20% and 50% densities. The experimental results demonstrate that hybrid infill designs significantly enhance both tensile and flexural strength compared to single-pattern configurations. Notably, the combination of honeycomb and triangular patterns yielded a 58% increase in tensile strength, while a grid and triangular pattern combination resulted in a 53% improvement in flexural strength. By elucidating the fracture mechanisms associated with these hybrid configurations, this research provides valuable insights for optimizing FDM part design and enabling localized reinforcement in additive manufacturing applications. |
