To construct a three dimensional material from a 3D printer specialty printing inks are required. These type of inks are called as 3D printing inks and manufactured from addition of 3D printing powder. Digitally controlled layering of 3D printing powder are used to make a three-dimensional object. Some of the important materials that are utilized in making 3D printing powder include tool steel, stainless steel, copper alloys, aluminum alloys, diamond catalyst alloys, titanium alloys, super alloys of chromium and nickel. 3D printing powder has characteristic packing density, and specific morphology that ensure uniformity and good flow in 3D printing of different objects. Some of the major techniques are used to produce 3D printing powder includes gas atomization, water atomization, centrifugal atomization, and plasma atomization.
