Abstract
Additive manufacturing, well known as 3D printing, is used to fabricate complex geometries and customized products. Freedom to design and waste minimization are key concerns of this technology. Additive manufacturing gains significant interest in many fields which includes aerospace, automotive, navy, and biomedical industries. In this technology, a geometrical CAD model is sliced into a number of layers and then stacked of material in layer-by-layer manner. In this review paper we discussed the various 3D printing methods and materials that are available now and current limitations, future trends of this technology.
