The purpose of this paper is to review the recent trends in the Metal 3D Printing. Metal 3D Printing holds a unique position in modern-day product development. It allows for the direct manufacturing of complex end-use parts and facilitates tooling for conventional manufacturing technologies, reducing costs and lead times.3D printing is a technology on the cusp, and therefore it is essential that you be fully prepared for its arrival. The only way to profit from great changes is to anticipate them in the very early stages and be ready to take advantages of the opportunities that they create. We are still at the beginning phase today, but major technical advanced are already heralding enormous business opportunities. 3D printing is a technique that converts a digital design in to tangible products by laying down consecutive cross section of materialism thin layers until it is built up.3D printing has been widely used in aerospace, Bio- Printing and automotive industries to create prototype of un usually shaped components. The material here has been meticulously researched and combined with uniquely specialized knowledge of overseas manufacturing, niche markets and emerging economies.
