Experimental Investigation on Combined ABS and PLA Materials Using 3D Printing FDM Machine

Fused Deposition Modeling (FDM) is a popular additive manufacturing technique used to build parts layer by layer. In this study, the mechanical properties of specimens made from the blends of Polylactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS) were investigated The goal was to determine if combining the two materials could enhance the mechanical properties of the resulting parts. Various compositions and parameters were used to produce specimens that were then tested for resistance against different tests such as tensile and flexural. The study was conducted by following the ASTM standards which are internationally recognized guidelines for testing and evaluating materials. During the FDM process, sandwich structure with ABS and PLA materials found some difficulty in preparing specimens, but their bonding is found good. During testing, bonding between ABS and PLA was strong. The results showed that the addition of PLA with ABS improved the mechanical properties of the parts, indicating that using the combination of these two materials could lead to an increase in strength. Therefore, it can be concluded that using blended PLA and ABS can be a viable alternative to pure ABS for achieving increased strength in FDM parts. From this S3 combination is best in flexural strength. It is concluded that S5 combination, i.e., with printing parameters 100% fill density and 45° orientation is more ductile than others.
