Effect of infill pattern scaling on mechanical properties of FDM-printed PLA specimens

Abstract 3D printing offers a significant advantage in the production of hollow parts through use infill patterns. However, these patterns are typically generated by slicer software with primary focus on providing basic structural rigidity, while neglecting other important criteria. This paper presents simplified scaling technique for fused deposition modeling (FDM) and evaluates its effectiveness tensile tests. The research question addressed this study is whether adjusting size pattern can reduce print time maintaining same stiffness at given ratio. methodology involves analyzing results obtained from findings reveal that be reduced to some extent properly pattern. it observed mechanical resistance influenced layer formation process. In conclusion, contributes understanding relationship between scaling, reduction, FDM printing.
