Laser metal deposition (LMD) belongs to the powder feed method. And selective laser melting (SLM) is another, which employs the laser beam to melt the pre-prepared powder bed [4,5]. Since both SLM and LMD have good ability to form the parts, some scholars have conducted the comparative research on the two manufacturing methods.

Methods of 3D Metal Printing - SPOTLIGHTMETAL

This technology includes Selective Laser Melting (SLS), which is also called Direct Metal Laser Sintering (DMLS) or Laser Metal Fusion (LMF). The term SLS is also used in plastic 3D printing, where the "S" at the end stands for "sintering". The average powder size is 20 to 50 µm, but also particles of up to 100 µm can printed.

Laser Metal Deposition | LMD | TRUMPF

The laser metal deposition process explained briefly. First of all, the laser beam heats up the workpiece locally, creating a weld pool. Fine metal powder is sprayed directly into the weld pool from a nozzle in the processing optics. It melts there and combines with the base material. A layer of approx. 0.2 to 1 millimeter remains.
