Definition av sintering. A process in which the particles of a powder are welded together by pressure and heating to a temperature below its melting point 

The area of interest The laser then begins its path for this layer, selectively sintering the powder into a solid. The sequence of dispensing a layer and sintering continues until part completion. After the part is left to cool, the surrounding loose metal powder is removed from the printer. 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.

After successfuly sintering of the first layer, a new layer of powder is spread over the previous one and the process is repeated. The sintered component is fully surrounded by powder thus providing support. Therefore – unlike SLA or Polyjet, support structures are not needed. Laser sintering takes a comparatively long time. Direct metal laser sintering (DMLS) is an additive metal printing technology that builds metal parts from a CAD file by selectively fusing stainless steel or aluminum powder into thin layers.

So  Aug 12, 2016 The process of selective laser sintering (SLS) involves selective heating and fusion of powdered material using a moving laser beam. Because  Jun 10, 2019 Working Process: · Powder is dispersed in a very thin layer on the top of platform inside of the build chamber. · The printer preheats the powder to a  Selective laser sintering 3D printers from Prodways feature premium additive Fundamental in Prodways' selective laser sintering process is the best-class  AM processes: stereolithography (SLA) and selective laser sintering (SLS). First, there's a difference between ultraviolet (UV) lamp cured and UV laser cured .

Laser sintering process

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 [52]. The manufacturing process is fully automated and computer controlled, following the computer-aided design (CAD) data of the processed geometry.

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 … 2013-08-14 DMLS means laser-sintering using a metal powder, in which metal parts are produced directly in the building process. The basic principle of the Direct Metal Laser Sintering (DMLS) Technology is to melt down thin layers (20 ÷ 60 µm) of Metal Powder with an electronically driven LASER beam (200W). 2020-01-13 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. Metal 3D Printing with Direct Metal Laser Sintering (DMLS) 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.

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.
