Selective laser melting (SLM) is one of many proprietary names for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering (DMLS), the ASTM standard term is powder bed fusion (PBF). PBF is a rapid prototyping, 3D printing, or additive manufacturing technique designed to use a high power

Selective laser melting (SLM) is one of the powder bed fusion additive manufacturing technology for metal. Its other name is direct metal laser sintering (DMLS), and they are often mentioned interchangeably. However, SLM melts a single metal while DMLS fuses/sinter metal alloys. On a molecular level, the laser melts the powder
Selective laser melting (SLM) is an additive manufacturing approach that falls under one of seven general categories defined by the ISO/ASTM known as powder bed fusion (to learn more, read our article all about powder bed fusion 3D printing ). In SLM, a high-powered laser selectively melts metal powder into a part in a layer-by-layer process.
Selective Laser Melting (SLM) is an industrial 3D printing process that uses similar technology to SLS. But unlike SLS, it creates parts additively by sintering fine metal powder particles. A high-power laser melts and fuses the metal powder into solid surfaces. One major difference with SLM technology is the sintering temperature.
Selective laser melting (SLM) is the premier metal 3D printing technology revolutionizing the additive manufacture of metal parts, but how does it work, and which 3D printers do it best? Most metal 3D printers use selective laser melting technology, which involves a laser that melts powdered metal. In fact, this method accounts for more than []

This study investigates the microstructure and mechanical properties of 430 ferritic stainless steel (FSS) fabricated via the selective laser melting (SLM) process. The mechanical properties and fracture morphologies of SLM-fabricated 430 FSS and conventional 430 FSS were compared in this paper.
The multi-component characteristics of high-entropy alloys (HEAs) endow them with excellent performance that many traditional alloys cannot match. However, there are still some limitations in the preparation of HEAs using traditional methods. Selective laser melting (SLM) technology can achieve the precision formation of complex
