Laser metal deposition (LMD) | TRUMPF

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.

Wire-based processes, on the other hand, build up the component by melting a wire-shaped filler metal, requiring the use of a laser, electron beam, or arc. These processes have a high deposition rate and therefore help to cut production times. Wire arc additive manufacturing is a wire-based process, and uses the gas metal arc welding process
