Abstract
The microstructures revealed characteristic melt pool patterns and laser scan tracks formed during the SLM process. Relative density values ranged from 97.3% to 98.27%, while hardness values varied between 126–128 HV. Tensile testing demonstrated clear anisotropic behaviour with variation in build orientation. The 45° specimens exhibited the highest elongation of 7.4%, whereas the 90° specimens achieved the maximum ultimate tensile strength of 450 ± 6 MPa. The observed variations were mainly attributed to differences in melt pool overlap and interlayer bonding. The results confirm that build orientation significantly influences the mechanical performance of as-built SLM AlSi10Mg alloy.
Keywords: Selective laser melting; AlSi10Mg; Build orientation; Anisotropy; Mechanical properties; Additive manufacturing.
