Selective laser sintering (SLS) is a rapid manufacturing process which uses powder material for fabrication of different parts directly from CAD drawing. Different common engineering thermoplastics such as polyamides, ABS, polycarbonate, and nylons, and for metal parts the materials such as titanium, stainless steel, and tool steel are broadly used for fabrication of parts [ 3 ]. In SLS manufacturing, powdered material [1] is heated to just below its melting point and then spread out into an even layer over the building platform [2] using a What is Direct metal laser sintering (DMLS)?. The direct metal laser sintering process (often abbreviated to DMLS) is controlled by a computer which instructs the Jul 16, 2019 Laser sintering is one of the leading commercial processes for rapid fabrication of functional prototypes and tools.

Two laser types, continuous-wave and pulsed lasers, have been success- fully used to sinter Ag nanoparticle ink. [13] The advan- tages of laser sintering over traditional oven sintering are 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). 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.

Selective Laser Sintering can be used to make parts using a variety of materials, including plastic, metal, ceramic, or glass The Selective Laser Sintering process involves tiny particles of polymer powders material being fused Powder bed fusion (PBF) additive manufacturing (AM) is the most popular manufacturing process for directly manufacturing of metallic parts. Processes using laser Other articles where Selective laser sintering is discussed: 3D printing: A related process is called selective laser sintering (SLS); here the nozzle head and Liquid phase sintering is one of the underlying principles that must be modeled and understood when the Selective Laser Sintering (SLS) process is used.

Direct metal laser sintering’s layer-by-layer printing allows multiple parts to be combined during the printing process.

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 med hjälp av en Direct Metal Laser Sintering (DMLS) 3D-skrivare. Den nya Form 3 och Form 3L har en ny process som företaget kallar … Denna process kan göras i varierande form och upplösning, vilket innebär att en och SLS (Selective Laser Sintering) - Laserstråle sveper över en bädd enligt Det handlar om en plattform som är automatiserad med systemet Direct Metal Laser Sintering, enligt ett pressmeddelande. Tanken är att skapa Direct metal laser sintering (DMLS), eller selective laser sintering (SLS) beter sig som en vätska vid träff, genom en process som kallas plastisk deformation.

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.

[20] employed SLS/SLM to process implants for medical purposes while Vasquez et al. [21] recently developed new SLS materials for snowboarding applications.
