Laser Material Deposition

Our range of services

At the Fraunhofer Institute for Laser Technology ILT, Laser Material Deposition (LMD) has been intensively researched and systematically developed for a wide range of applications and industries for more than 30 years.

With LMD, metal layers with thicknesses between 0.01 mm and 2 mm can be applied with high precision to almost any metallic material in a very short time. By overlapping several deposited tracks, two-dimensional coatings, for example for wear and corrosion protection or functional coatings, can be produced. If several layers are deposited on top of each other, the process can also be used for additive manufacturing including processes for repair applications and individualization of prefabricated parts (hybrid AM). Due to the precisely controllable energy input, components and alloys that are generally considered difficult to weld can be processed. The easy adaptability and flexibility for different fields of application (coating, repair and additive manufacturing) and its simple integrability into existing process chains make the process particularly attractive for small and medium-sized enterprises.
