| Abstract | ||||
| This paper investigates the influence of various filling strategies and infill percentages on the ultimate tensile strength (UTS) and build time of polylactic acid (PLA) objects produced using Fused Deposition Modeling (FDM). The research focused on three infill percentages: 25%, 50%, and 75%, along with four distinct filling strategies: Cross, Cross 3D, Triangles, and Tri-Hexagon. Tensile test specimens were prepared following ASTM D638 standards, with Ultimaker Cura software employed to determine build times. The findings revealed that the Triangles filling strategy provided the highest UTS at 50% and 75% infill, while the Cross-3D strategy consistently delivered the lowest UTS across all percentages. Regarding build time, the Triangles and Tri-Hexagon strategies were the most efficient, offering the shortest building durations. The study concludes that UTS improves as the infill percentage increases, and it ranks the strategies based on both strength and build time, offering practical insights for optimizing FDM printing parameters for PLA materials, and balancing mechanical performance with manufacturing efficiency. | ||||
