Powder metallurgy (P/M) is known as an industrial part manufacturing by powder pressing and sintering using ceramic and metal based particulars, but, P/M method has incorperated the additive manufacturing as a new method which is combined in technologies of laser, machine, design and software. The manufacturing of prototype and/or useful industrial parts has become possible as layer upon layer with today's additive manufacturing technology by using suitable laser, electron and ultraviolet beam in form of powder, wire, sheet and melt from polymer, ceramic and metal based materials. The literature survey has been done about the powder bed/feed additive manufacturing methods, the powder characterizations used in these methods and powder manufacturing methods in this study. In addition, the effect of dimension, shape, physical properties, and chemical purity of powders on the product properties manufactured by powder bed/feed additive manufacturing can be expressed with respect of investigations in the literature.
