Selective laser melting (SLM), a powder bed fusion metal additive manufacturing method, is used in the biomedical, defence, aerospace, and automotive industries to create highly customized and value-added products. AlSi10Mg has a surface finish of 30 microns during the SLM printing process, hence post processing is required to smooth up the surface. For the vertical and horizontal direction printing of AlSi10Mg material during fine finishing of the surface roughness, the maximum surface finish achievable after post processing approach is around 5 microns. The hardness is improved in horizontal direction than the vertical direction printing of the AlSi10Mg in SLM process. The hardness is influenced with highest silicon percentage and it showed 183Hv. The tensile strength results higher in vertical direction than the horizontal direction. The maximum tensile strength is 590.777MPa and good elongation is 6.965 achieved in vertical direction. The microstructure shows the influence of elements to support the maximum tensile strength. The theoretical results of the printing AlSi10Mg in SLM process using ANSYS for the maximum tensile strength, deformation and load absorption capacity. Also compare the results with experimental analysis in various directions of the printing in SLM process. The maximum stress is 513.01MPa, Strain is 0.46 and total deformation is 45mm in SLM process using theoretical analysis. [ABSTRACT FROM AUTHOR] |
