Abstract
The growing application of additive manufacturing (AM) has revolutionized modern production, offering design freedom, material reduction, and rapid production. Of the various AM processes, Laser Powder Bed Fusion (L-PBF) is a leading process for manufacturing metal components with complex geometries and high mechanical properties. Its capability to utilize advanced materials like AlSi10Mg makes it attractive for aerospace, automotive, and biomedical applications. However, L-PBF is challenged with maximizing productivity, quality of parts, and reducing costs. In this study, the influence of major process parameters on AlSi10Mg manufacturing is investigated to enhance productivity while ensuring high-quality, low-cost production. The present study targets four key L-PBF parameters—layer thickness, laser power, scan speed, and hatch distance—and their influence on critical quality factors like density, porosity, surface roughness, and mechanical properties.
In addition, a cost analysis examines the economic feasibility of the different processing conditions
