Laser metal fusion
Laser metal fusion is often referred to as metal 3D printing, powder bed fusion, or selective laser melting. The laser builds up the workpiece from a powder bed, layer by layer.
Laser metal deposition
Laser metal deposition is also referred to as LMD, direct energy deposition, or laser cladding. The process is quite simple: The laser first generates a weld pool on the component surface. A nozzle then automatically adds metal powder. This creates beads that are welded to one another, which then form structures on existing base bodies or entire components.
