Due to the local heat input of a focused laser beam, material properties in the surface region of a component can be adjusted while at the same time achieving minimal distortion. Furthermore it is possible to produce components almost without geometric restrictions (construction of new parts), and/or repair damaged components. Applications for Laser Additive Manufacturing are seen in areas such as tool and mold manufacturing, turbo machinery, aerospace, medical, automotive and electrical engineering. This presentation gives an overview on the technological potentials as well as on the current R&D trends for the laser-based processes Selective Laser Melting (SLM) and Laser Metal Deposition (LMD).
