Direct Metal Laser Sintering (DMLS) is an additive manufacturing process. Parts are built using a laser to selectively sinter (heat and fuse) a powdered metal material into layers. The process begins once a 3D CAD file is mathematically sliced into multiple 2D cross sections and uploaded into the system.

ABSTRACT An analytical ray tracing model is developed to simulate the energy absorption and penetration during the selective laser sintering (SLS) of metal powders. The model is applied to a Fe-Cu powder mixture. It gives an evaluation of the energy absorption and penetration and an estimation of the sintering zone dimension.

Laser additive manufacturing (LAM) is a layer wise fabrication method in which a laser beam melts metallic powder to form solid objects. Although 3D printing has been invented 30 years ago, the industrial use is quite limited whereas the introduction of cheap consumer 3D printers, in recent years, has familiarized the 3D printing.
