3D printing ( additive manufacturing) has been around for more than two decades now. with improvement in technology and increasing industry participation, 3D printing is moving to the mainstream manufacturing from being a mere tool for prototyping. One of the key factors inhibiting the adoption of 3D printers in the manufacturing sector was the limited options of materials. Photo-polymers and plastics have been the dominant material in past. However, metal is now being widely used and being widely seen as the future material of the industry.
