AN OVERVIEW OF ADDITIVE MANUFACTURING – APPROACHES, TECHNIQUES, TRENDS AND CHALLENGES IN MANUFACTURING SCENARIO

Nowadays, Additive Manufacturing (AM) otherwise called 3D (Three Dimensional) Printing is a prominent one in the emerging industrial scenario. The domain called Additive Manufacturing (AM) is an emerging technology for multifaceted applications, developing novel materials and exhibiting excellent mechanical, physical and chemical properties of the end product. The Additive Manufacturing technique of bottom-up approach which is beneficial than Conventional Methods of top-down approach in all aspects except certain limitations like Production time; Product Size; Setup Cost; Statutory Regulations. Irrespective of the challenges, there is a scope for commercializing AM products in the global market, which in turn leads to the production savings of less than 50% and an increased production speed of more than 400 % when compared to conventional methods of optimizing the constraints. The aim of the paper is to overview of Additive Manufacturing on modeling approaches, techniques, trends and its challenges in the application of AM to attain its full potential
