Selective laser melting(SLM) is apowder bed fusionprocess that uses a laser beam to fusemetallic powdersselectively, layer by layer, and based on a CAD file. The schematic of this process is shown inFig. 3. It consists mainly of a powder bed, a roller/wiper to spread the powder, a bu...
Selective Laser Melting (SLM) is an Additive Manufacturing (AM) process that can produce near-net shape products from metallic powders, in a layer-by-layer fashion, directly from three-dimensional Computer-Aided Design (CAD) models. Besides being capable of printing complex geometries and allowing ...
The high-energy laser beam of the selective laser melting (SLM) equipment melts the metal powder dispersed on the substrate in a protective atmosphere along the planned three-dimensional model path (Ref1). The metals change rapidly from liquid to solid. The process is repeated until the forming...
For instance, decreasing the scanning speed leads to melting pool expansion and a higher density of the final product, while increasing the laser power or reducing the scan line spacing result in lower porosity. A schematic illustration of SLM process parameters is shown in Fig. 3. According to...

The selective laser melting (SLM) is a common additive manufacturing technology. SLM formation involves complex multiphysical phenomena, such as heat transfer, melting, molten flow, and solidification. The development of a numerical method for modeling multitrack powder melting in SLM has important scie...
Selective Laser Melting (SLM) is one of the additive manufacturing processes. It is relatively mature and has been a research focus in manufacturing metallic parts [6]. A schematic layout of a typical SLM setup is presented in Fig.1[7]. During the SLM process, data is provided from a CAD...
