Direct metal laser sintering (DMLS) is an additive metal fabrication technology, occasionally referred to as selective laser sintering (SLS) or selective laser melting (SLM). This process utilizes a 3-dimensional CAD model, creating a file which is then forwarded to the software utilized by the machine. The operator utilizes the aforementioned 3-dimensional model to correctly align the geometry for the purpose of building parts and implements support structures wherever necessary. The direct metal laser sintering machine makes use of a powerful fiber optic laser. Within the build chamber is a platform for material dispensation and a build platform, in addition to a recoater blade which moves new powder on top of the build platform. With a focused laser beam, this DMLS technology melts metal powder locally to fuse it into solid parts. Parts are constructed additively, one layer at a time. Each layer is usually 40 micrometres thick. This direct laser metal sintering process facilitates the creation of very complex geometries derived from 3-dimensional CAD data. The process is completely automated and is usually completed within just a few hours. DMLS is a net-shape process, accurately creating parts that yield, high resolution, great surface quality and excellent mechanical properties.
