With the rapid improvement of technology, Additive Manufacturing is created to increase productivity. It is defined as the process of making products through fusing/adding materials layer by layer, which is the direct opposite of Subtractive Manufacturing.

It is based on three categories – liquid, solid or powder-based system. For this research, the main focus will be on Selective Laser Melting (SLM) which is a powder-based system.
