Abstract
Additive manufacturing (AM) technology plays a vital role in manufacturing components for the validation of designs. However, the strength of end-user functional components using fused deposition modeling (FDM) is yet a space of flow research. Polylactic acid (PLA) is a bio-degradable material regularly utilized in the FDM-based 3D printing process. This research paper focuses on process parameters such as layer thickness, infill geometry, and the number of perimeter on tensile strength of PLA samples. The finite element (FE) simulation has been performed on 3D printed parts to predict von-Mises stress and tensile strength. The simulation process involves the preparation of parts in SolidWorks and then subjected to tensile loads in ANSYS to calculate desired results. Three different simulation approaches have been employed and compared to obtain accurate results. The simulated results have also been compared with experimental tensile strength value for 3D printed parts fabricated using PLA material in Pursa MK3S FDM printer, exposed to tensile testing in the universal testing machine. The results revealed that the percentage variation of tensile strength for simulation and experimental results has been found in the range of almost 20%. The work proposed to simulate their behavior under tensile loads for future examination on the coupled effects of processing parameters.
