Laser Sintering Process an overview ScienceDirect Topics

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.

What is Laser Sintering? XponentialWorks

Selective Laser Sintering (SLS) is an additive manufacturing technique in which a laser is used sinter powdered material into a solid structure. Unlike3D printing, in which a liquid substrate is deposited layer-by-layer to form the item being produced, laser sintering forms the end-product by using the heat from a precisely-focused laser that coalesces a powder substrate into a solid mass.

Direct Metal Laser Sintering an overview ScienceDirect

Direct laser metal sintering (DLMS), also referred to as direct laser metal forming (DLMF) and selective laser melting (SLM), is a method wherein a highly intensive laser beam is directed onto a metal powder bed and fused metal particles according to a computer-aided design file (Shibli et al., 2013). This technology is an extension of the SLS process, which also regenerates real 3D parts from layer-by

Selective laser sintering Wikipedia

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

Selective Laser Sintering 3D Systems

Selective laser sintering is a powder-based 3D printing technology that uses a laser to fuse material layers into a final part. After the laser traces a cross-section of the CAD design(s) onto a material layer, the build platform lowers and another layer is fused on top. The build platform continues to lower until every layer is built and the part is complete. 3D Systems' SLS materials include
