Abstract

Additive manufacturing (AM) distinguishes itself from the traditional manufacturing method in that the process is fast and there is no need for expensive tooling, mold, dies etc and the process is capable of fabricating complex, customized parts derived from digital data. Magnesium is one of the most highly important lightweight metals used in automotive application to reduce vehicle weight. Its applicability in implant sector for orthopedic application is also getting acceptance. Currently, polymers have occupied most of the implant applications but superior qualities like ductility, strength and biodegradability established Mg alloys as a better choice for orthopedic implants [1]. Biodegradable Magnesium induces very small amount of stress shielding and it eliminates the necessity of secondary surgery. Additive manufactured specimen, made of Magnesium alloy, is getting popularity in structural, aviation and automobile sectors and they can be a good replacement for expensive Aluminum, Cobalt and Titanium based alloys. The sector is promising but being new, very small amount of work has been done on evaluating mechanical properties. Mechanical behaviors like tensile strength, compressive strength and fatigue properties largely depend on cavities present in the specimen. In this paper, the author described selective laser melting (SLM), paste extruding deposition (PED), friction stir additive manufacturing (FSAM) and laser additive manufacturing (LAM) techniques to fabricate Magnesium alloy based 3D printed specimen and discussed their mechanical behaviors.
