Abstract: State-of-the-arts method about laser additive processing, which is used to manufacture components and moulds by adding not reducing materials, is reviewed and discussed. This novel technology can be used in many fields such as military, automotive and aerospace industries. The surface roughness, inefficient filling, interlayer stress, porous and cracking can be eliminated by further development of the technology. Reactive laser additive processing will be a suitable method for synthesizing intermetallics and metal matrix composites.
