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 … 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.

En DML-skrivare använder en Yb-laser på 200 W eller mer. Denna DML, Direct Metal Laser Sintering in the Tool/Die manufacturing process/production.

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 HAp powders have been characterized based on their laser sintering ability with the variation of process parameters like spreading behavior, different grain 

Unlike the direct metal Laser sintering process, melting actually creates a pool where the materials can consolidate before reforming and hardening to create a new solid structure. 2015-05-19 Selective laser sintering (SLS) is a powder bed 3D printing technology that produces highly accurate and durable parts capable of being used directly in end-use, low-volume production. SLS is a newer 3D printing process that is often thought of as a cousin to the popular metal 3D printing technology direct metal laser sintering (DMLS). Metal Laser Sintering (MLS) is very similar to the Selective Laser Sintering process (SLS), with the addition of atmosphere controlled build tanks and higher output lasers. MLS uses powdered metal to create solid metal parts. MLS unlocks the potential for designs that would typically be impossible to build with conventional machining methods Metal laser sintering process on a Farsoon FS271M system (left) and an metallographic image of an as-built H13 part (right).

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. Selective laser sintering of inkjet-printed silver nanoparticle inks on paper of divalent Ytterbium in the photodarkening process of Yb-doped fiber lasers.

After successfuly sintering of the first layer, a new layer of powder is spread over the previous one and the process is repeated.

Chart courtesy of Farsoon Technologies 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. during the sintering process. In terms of the signature of acoustic signals, two phases can be roughly separated, i.e. internal laser sintering (0– 10.1 s) and boundary laser sintering (10.1–11s).
