3D SLS Sintering

Selective laser sintering (SLS) is an additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal), 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 direct metal laser sintering ; the two are instantiations of the same concept but differ in technical details. Selective laser melting uses a comparable concept, but in SLM the material is fully melted rather than sintered,allowing different properties (crystal structure, porosity, and so on). SLS  is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume production of component parts. Production roles are expanding as the commercialization of AM technology improves.
