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. While Deckard and Beaman patented the process of selective laser sintering, they were far from the first to use sintering — the process of creating objects from powders using atomic diffusion — to selective laser sintering process. The CO2 laser is often used to sinter successive layers of powder instead of liquid resin. Parts are built upon a platform which sits just below the surface in a bin of the heat-fusible powder. A beam of laser then traces the pattern on the very first layer thereby sintering it together. Selective laser sintering (SLS) is an Additive Manufacturing (AM) process that yields excellent part qualities with good mechanical properties.
Selective laser sintering (SLS) is an Additive Manufacturing (AM) process that yields excellent part qualities with good mechanical properties. The SLS process employs micron-sized polymer particles, which are Schematic of the selective laser sintering process. SLS 3D printing uses a high power laser to sinter small particles of polymer powder into a solid structure based on a 3D model. Printing: The powder is dispersed in a thin layer on top of a platform inside of the build chamber. The Selective Laser Sintering process allows for the production of large and small prototype components in a range of tough, highly functional materials.. Please note that the build platform dimensions represent single part builds, larger components can be “split and bonded” by our team of highly trained in-house model makers. The sintering process takes place in furnaces that cool materials at a rate consistent with the creation of martensitic, crystalline structures.
This runs counter to traditional manufacturing processes where additional design complexity usually involves greatly increased time and expense.

Laser sintering is an additive manufacturing technology with which components can be built in a materials layering process on the basis of digital 3D design data. The term “3D printing” is being used more and more as a synonym for it.

According to the ASTM designation F2792, Standard Terminology for Additive Manufacturing Technologies, laser sintering is defined as a “powder bed fusion process used to produce objects from powdered materials using one or more lasers to selectively fuse or melt the particles at the surface, layer by layer, in an enclosed chamber.”
Selective Laser Sintering, or SLS, is an additive manufactured process that uses a laser to fuse thin layers of nylon powder to create parts. SLS technology
Laser additive manufacturing often work as follows, with a method called stereo lithography:. One starts with a bath of liquid or powder, having a smooth surface. A laser beam is then moved over the top surface, irradiating some parts of it, causing the solidification, while not hitting other parts.

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 Direct metal laser sintering (DMLS) is one type of additive manufacturing process that allows layer by layer printing of metal parts having complex geometries directly from 3D CAD data. It uses a high-energy laser to sinter powdered metal under computer control, binding the material together to create a solid structure.
