文摘：The utilization of 3D printing metals has gained considerable traction as a manufacturing technique within the automotive and aerospace sectors, leading to a demand for more efficient and cost-effective methods. In this article, the connecting rod (CR) of the two-wheeler's four-stroke engine underwent a redesign, analysis, and printing process using SS17-4PH gas atomized stainless steel powder through selective laser melting (SLM). The redesign aimed to reduce weight while maintaining strength in SolidWorks. Ansys 18.1 was used to perform finite element analysis (FEA). A comparison was made between the overall deformation, elastic strain, Von-Mises stress, safety factor, life, damage, and weight reduction of the optimized CRs and the original CR. The analysis was conducted under a load of 616 N, which is double the actual load on the CR. Subsequently, the optimized CR was printed using SLM. The study revealed that the weight of the optimized CR is significantly lower than that of the original. Furthermore, the modified CR is expected to have a similar lifespan to the original CR.
