Abstract

Additive manufacturing (AM) is increasingly used for producing lightweight and complex metal components with reduced material waste and shorter production time. Selective laser melting (SLM) is widely employed for manufacturing AlSi10Mg alloy parts for aerospace and automotive applications. In the present work, the influence of build orientation on the microstructure and mechanical properties of SLM-fabricated AlSi10Mg alloy was investigated. Samples were fabricated at 0°, 45°, and 90° orientations and analysed using microstructural, density, hardness, and tensile characterization techniques.

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.
