Given the existing limitations in the plastic parts manufacturing industry, where producing a high-quality component generally requires substantial investment in mold fabrication and production machinery setup, manufacturing parts in limited quantities presents significant challenges. Over the past four decades, with the remarkable advancement of additive manufacturing technologies, the use of these methods for replacing limited-production parts has become increasingly widespread. Considering several printing patterns and infill densities, this paper investigates the mechanical characteristics of PLA parts produced by the FDM process. Then, the fabricated parts, produced using four common printing patterns and five different infill densities, were subjected to tensile testing, and the results were analyzed. The results indicate that while the thermal history of the printed rasters directly influences layer bonding, its effect on the tensile strength of the parts is relatively minor compared to the layer arrangement. Additionally, the findings reveal an approximately linear increase in tensile strength for printing patterns that effectively connect ends of the part during fabrication. Finally, the outcomes of this study are provided as practical appendices for industrial applications, aiming to balance both the performance and economic feasibility of FDM-manufactured parts.
