When the powder to be fused is metal, the terms direct metal laser sintering (DMLS) and direct metal laser melting (DMLM) are commonly used. SELECETIVE LASER SINTERING 2. The laser heat input was modelled by an internal heat source, as was demonstrated by Kossolov et al. The laser used for experiments has a Gaussian power density distribution; in the The laser must have a greater power than the SLS and at the end of the process the manufactured objects is quite similar to series production, in fact, it does not require s pecial surface finishes and may be subjected quietly at conventional machining. •Offers the key advantage of making functional parts in essentially final materials. The powder feed is contained in [5]. Selective laser sintering is an additive rapid prototyping technique that uses a high power laser to fuse small particles of thermoplastic, metal, polyamide (nylon), ceramic, or glass filled nylon.

News; Printables; Buyer's Guides; Reviews; Basics; Pro . Selective laser melting is a very high-energy process, as each layer of metal powder must be heated above the melting point of the metal. Get it 3d printed All3DP is an editorially independent publication.

studies in Texas University in 1987. Selective Laser Sintering is one of the main 3D printing technologies used, though SLS 3D printers have been around since the late 1980s. + Selective Laser Sintering (SLS) •Invented by Carl Deckard during his PhD. News Printables Buyer's Guides Reviews Basics. SLM works on the principle of melting. The laser used for experiments has a Gaussian power density distribution; in the The process of Selective Laser Sintering is actually quite simple. Selective laser melting (SLM), also known as direct metal laser melting (DMLM) or laser powder bed fusion (LPBF), is a rapid prototyping, 3D printing, or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together. A typical SLS or SLM process is illustrated in Fig. Also Explore the Seminar Topics Paper on Selective Laser Sintering with Abstract or Synopsis, Documentation on Advantages and Disadvantages, Base Paper Presentation Slides for IEEE Final Year Mechanical Engineering ME or Production Automobile Students for the year 2019 2020. During the SLM process, a product is formed by selectively melting successive layers of powder by the interaction of a laser beam. The laser heat input was modelled by an internal heat source, as was demonstrated by Kossolov et al. Along with fused deposition modeling and stereolithography, SLS has dominated rapid prototyping and low number manufacturing for decades..
