4.selective laser sintering (by Hari Prasad) 1. SELECETIVE LASER SINTERING 2. SELECTIVE LASER SINTERING TECHNOLOGY SLS is a rapid prototyping (RP) process that builds models from a wide variety of materials using an additive fabrication method. The build media for SLS comes in powder form, which is fused together by a powerful carbon dioxide laser to form the final product

The temperature of the powder along with the (incomplete) parts must be controlled within 2 °C during the three stages of preheating, sintering, and storing before removal to minimize warping, stresses, and heat-induced distortion. Selective laser sintering is an additive manufacturing technique that uses a laser as the power source to sinter powdered material, aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. It is similar to selective laser melting; the two are instantiations of the same concept but differ in technical details. SLS is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume produ Laser-Sintering, which means, methods that helps in the manufacturing of solid parts by solidifying powder like materials layer-by-layer, exposing the surface of a powder bed with a laser or other high energy beam. The laser sintering process is characterised by extreme rapid sintering and solidification.

However, the  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). Selective Laser Sintering (SLS) is an Additive Manufacturing process that belongs to the Powder Bed Fusion family. In SLS, a laser selectively sinters the  Selective Laser Sintering, SLS, bygger 3D-objekt lager för lager genom att låta en laserstråle sintra samman pulver enligt detaljens tvärsnitt.

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. Direct metal laser sintering’s layer-by-layer printing allows multiple parts to be combined during the printing process. 2019-09-03 · Today, we will focus on Laser Powder Bed Fusion (LPBF), which, as its name suggests, uses a laser to additively manufacture a metal part. In 1994, EOS patented its process called Direct Metal Laser Sintering (DMLS), while in 1995 the Fraunhofer Institute introduced the term SLM for Selective Laser Melting.

Firstly, the roller within the metal 3D printer spreads out a thin layer of powder in the 3D printer’s empty tank. This powder layer is spread to be the same as the height of one layer (usually 20-100 microns). The print chamber of the 3D printer is then heated up. The build begins with dispensing a thin layer of metal powder onto the build platform. 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. 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.

It is similar to selective laser melting; the two are instantiations of the same concept but differ in technical details. SLS is a relatively new technology that so far has mainly been used for rapid prototyping and for Selective laser sintering (SLS) is a popular powder-based AM process, which utilizes a scanning laser beam (e.g., CO 2 laser) to sinter the powdered materials. After the first layer is solidified, the powder bed moves downward, allowing a new layer to be added on the top and the process is repeated until a 3D part is obtained. 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 DMLS means laser-sintering using a metal powder, in which metal parts are produced directly in the building process.

The machine was equipped with a 60 W continuous wave CO 2 laser and a peristaltic pump for slurry deposition. The process chamber was filled with inert N 2 gas in order to prevent thermal oxidation of the PVA. In this process, laser automatically aims at points in space defined by a three-dimensional (3D) model, binding the material together through sintering process to create a solid structure. 1 An important type of metal used in DMLS technique is nickel based alloy, e.g., Inconel 625 and 718. 2 Inconel alloys are oxidation and corrosion resistant materials which are well suited for service in Direct metal laser sintering Direct metal laser sintering (DMLS) is an AM process [1] by which digital 3D design data (Fig. 1a) is used to build up a component in layers by depositing metal material.
