Abstract

Selective Laser Melting (SLM) is an advance Additive Manufacturing (AM) technique in which a component is manufacturing in a layer by layer manner by melting the top surface of a powder bed with a high intensity laser according to sliced 3D CAD data. AlSi10Mg alloy is a traditional cast alloy that is often used for die-casting. Because of its good mechanical and other properties, this alloy has been widely used in the automotive industry. In this work, the effects on the relative density is investigated for SLM-produced AlSi10Mg parts on one factor at a time (OFAT) basis by keeping constant various parameters such as laser power, scanning speed and hatching distance. It is shown that AlSi10Mg parts produced by SLM having best relative density values are at 350 watt laser power, 1650 mm/s of scanning speed and hatching distance of 0.13mm.
