Direct metal laser solidification/sintering (DMLS) is the Industrial 3D printing technology that directly create a metal part from its 3D computer model. This process is an advancement of all Manufacturing methods.The working material for this Industrial 3D printing process is finely powdered metal. Typically, the manufactured size of the metal particles is in microns The CAD model is divided into many fine layers, which are then printed one-by-one to build the final part.
