In that process, one may introduce another metal with lower melting point (e.g. copper), which fills the microscopic voids in the porous structure of the The laser sintering (LS) process uses a laser source to provide thermal energy and selectively fuse together particles of a powder material into complex three-dimensional shapes in a layer-by-layer strategy . The manufacturing process is fully automated and computer controlled, following the computer-aided design (CAD) data of the processed Laser sintering is a commonly used sintering process, and direct laser sintering (also known as selective laser sintering or selective laser melting) is one particular laser sintering process. In this type of sintering process, a directed energy beam in the form of a laser moves across a bed covered with a thin layer of metallic powder. The laser sintering/milling hybrid process can be ideal for manufacturing molds. It can make use of four different materials: hot rolled steel, maraging steel (H13 equivalent that can be heat-treated to 52 Rockwell after it comes out of the machine), 630 stainless steel and 316L stainless steel.

In selective laser sintering (SLS), the process used by UTHSCSA/UTA, components are built by material addition rather than by material removal by using a directed laser beam that causes individual particles to fuse in selected regions of space. The process begins by ﬁrst depositing a thin layer of powder into a container. Direct metal laser sintering (DMLS) is an industrial metal 3D printing process that builds fully functional metal prototypes and production parts in 7 days or less. A range of metals produce final parts that can be used for end-use applications. Selective Laser Sintering Additive Manufacturing Technology is a unique and comprehensive guide to this emerging technology. It covers in detail the equipment, software algorithms and control systems, material preparations and process technology, precision control, simulation analysis, and provides examples of applications of selective laser Another method is indirect sintering or two-step sintering, where the laser treatment creates only a preliminary porous structure, which afterwards is sintered again with a heat treatment.

Apr 13, 2019 It's used for both for rapid prototyping and mass production of metal parts. The method is very similar to selective laser melting (SLM), also Selective laser sintering is a 3D printing method that builds durable plastic parts for prototyping and low-volume production. Aug 13, 2013 Additive manufacturing, or 3D printing, is the process of turning digital used by today's 3D printers is called selective laser sintering (SLS).
The process will be repeated until the desired part is created. Compared to other additive manufacturing processes such as stereolithography (SLA) and Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF), Selective Laser Sintering (SLS) does not require support structures since the powder acts as self supporting material. Selective laser sintering fabricates complex plastic parts and assemblies in a single process, one layer at a time.
The term “3D printing” is being used more and more as a synonym for it. Selective laser sintering SLS Additive Manufacturing is a 3D printing process that uses a high powered laser to fuse small particles of plastic powders into the desired three dimensional shape. Prototypes manufactured using this 3D printing technology provide customers with tough, durable parts even capable of being used directly in end use low volume production.
The process is likened to Selective Laser Sintering (SLS), however, instead of a laser dictating the sintered cross sectional area of
Selective Laser Sintering (SLS) is an additive manufacturing process that can efficiently produce durable nylon end-use parts and prototypes.

Carl Deckard developed and patented SLS while studying under Joe Beaman […] 2014-01-01 laser powder bed fusion (aka selective laser sintering (SLS) are chosen. In this process, a homogeneous layer of powder is spread onto a building platform. The temperature in the manufacturing system is set between the onset of melting and the onset of crystallization of the … Laser sintering is a layer manufacturing technology (see Figures 1 and 2).
