Direct Metal Laser Sintering Of Alsi10mg Alloy For Aerospace Application: A Review Of Current Literature

Abstract

Additive Manufacturing (AM) has the main benefits of freedom of design, mass customization, waste minimization and the ability to manufacture complex shape. AM is the process of making 3D object from computer model data by depositing of material layer by layer. In this research mechanical properties are investigated on AlSi10Mg alloy made by Direct Metal Laser Sintering (DMLS) and also provides this paper layer-by-layer additive process simulation before the DMLS printing process, which saves time, cost, and material. The quality and performance of the additive manufactured (AM) parts depends on the build orientation. A model based on an L9 orthogonal array of Taguchi design experiments was created to perform the mechanical properties such as tensile strength, metallurgical structure and hardness for AlSi10Mg alloy. The DMLS- AM high production cost associated with laser power, scan speed, hatching distance and layer thickness for process parameters optimization on mechanical properties.
