Laser metal deposition is a generative manufacturing method for metals. Internationally, it is generally known as “laser metal deposition”, abbreviated to LMD. People also talk about “direct metal deposition” (DMD) or “direct energy deposition” (DED). The process is easy to explain. The laser creates a weld pool on the component surface. Metal powder is automatically added via a nozzle. Beads that are welded together are formed, resulting in structures on existing base bodies or entire components. The process is used in industries such as the aviation and aerospace industry, energy technology, petrochemicals, the automotive industry, as well as medical technology. TRUMPF customers benefit from a wide range of lasers and laser systems, process expertise, and services for numerous applications. This means LMD technology can also be combined with laser welding or laser cutting.
The laser generates a weld pool on the component surface. A metal filler material is then continuously added and melted on in this pool. In this manner, beads that are welded to one another are created, which then form structures on existing base bodies for repairs or coating, or form entire components
