The technology was established in the 1980s and has been commercially used since the 1990s. Unlike some other forms of additive manufacturing, SLS isn’t suited (in most cases) to residential use. This article from EOS addresses all three questions by explaining the laser sintering process, focusing on one metal—EOS titanium Ti64—to demonstrate how DMLS provides solutions to real-world manufacturing problems.

SLS process involves spreading of polymer powders, which also serves as self-supporting basement, on the stage and application of laser light to fuse fine polymeric powders into selective layers into final object [6,62]. From: Composite Structures, 2020. Related terms: Fabrication; Sintering; Additive Manufacturing; Nanoparticles Selective laser sintering ( SLS) is an additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically nylon or polyamide ), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. Fig. 4 (a) schematically illustrates the SLS manufacturing process in which a thin powder layer is spread over a platform using a leveling roller and is selectively sintered by a controlled scanning laser beam, usually a CO 2 laser, according to the sliced pattern. Se hela listan på llfurnace.com Selective Laser Sintering (SLS) is a type of additive manufacturing process that uses a laser as a thermal source for fusing ceramic, glass, plastic, metal powder and others into a 3-dimensional object. Many consider SLS to have the most diverse list of viable materials.

The term “3D printing” is being used more and more as a synonym for it. Selective laser sintering SLS Additive Manufacturing is a 3D printing process that uses a high powered laser to fuse small particles of plastic powders into the desired three dimensional shape. Prototypes manufactured using this 3D printing technology provide customers with tough, durable parts even capable of being used directly in end use low volume production.

systems, including the laser system–optical train (a) deflecting a 50 W CO 2 laser beam in the X and Y dimensions to sinter selectively the preheated surface Inverted Laser Sintering We have developed an additive manufacturing process that uses an upward-directed laser to fuse a monolayer of powder onto a substrate through a clear surface. The process is then repeated to build a hanging part layer by layer, by replenishing powder on the glass, or moving to a second plate with a different powder. Additive manufacturing: Laser sintering Laser sintering is a powder bed process that uses a laser as a power source to sinter powdered material. Understanding the material at a microstructure level is critical to the development of materials for laser sintering. According to the ASTM designation F2792, Standard Terminology for Additive Manufacturing Technologies, laser sintering is defined as a “powder bed fusion process used to produce objects from powdered materials using one or more lasers to selectively fuse or melt the particles at the surface, layer by layer, in an enclosed chamber.” Selective Laser Sintering, or SLS, is an additive manufactured process that uses a laser to fuse thin layers of nylon powder to create parts.

The process is likened to Selective Laser Sintering (SLS), however, instead of a laser dictating the sintered cross sectional area of Selective Laser Sintering (SLS) is an additive manufacturing process that can efficiently produce durable nylon end-use parts and prototypes. SLS provides a number of benefits, including the ability to manufacture high precision and complex parts without the need for tooling or molds. Selective Laser Sintering (SLS) is one of the most used Additive Manufacturing technologies to produce structural plastic parts.

The laser sintering/milling hybrid process can be ideal for manufacturing molds. It can make use of four different materials: hot rolled steel, maraging steel (H13 equivalent that can be heat-treated to 52 Rockwell after it comes out of the machine), 630 stainless steel and 316L stainless steel.

Direct metal laser melting offers short lead times ideal in situations where repeated testing of functional metal prototypes is necessary.
