Additive manufacturing has become a highly researched topic in recent years all over the world. The 6061 series is a precipitation hardening alloy; containing magnesium and silicon (Si-Mg), 6061 aluminum is used extensively as a construction material, most commonly in the manufacture of automotive components and well-suited to the construction of motorcycles, bicycle frames, camera lenses, fishing reels, electrical fittings, & couplings, valves. In the present work investigation has been done to evaluate the effect of selective laser melting process parameters like (laser power, laser exposure time, spot size) on the microstructure and mechanical properties (Vickers hardness, wear resistance) of additive manufacturing Al-alloy was characterized. In the porosity of AlSi10 Mg in SLM done by various conditions altered the microstructure of all Specimens, Hardness is characterized by micro indentation on samples along building direction (along z-axis) and Wear resistance of frictional force values, and wear values of the specimens were plotted on graph according to the above mentioned working conditions. The obtained results demonstrate how these alter microstructure & hardness and wear resistance of additive manufacturing Al-alloy. AM has expanded over the last five years or so to include applications in many areas of our lives. From prototyping and tooling to direct part manufacturing in industrial sectors such as architectural, medical, dental, aerospace, furniture and jewellery, new and innovative applications are constantly being developed.
