Selective laser sintering - Wikipedia

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.It is similar to selective laser melting; the two are instantiations of the same concept ...

Selective Laser Sintering (SLS) : Additive Manufacturing

Selective Laser Sintering (SLS) is a printing and manufacturing process that is ideal for quick-turn prototypes or for short-run production. Parts made from SLS are much more robust and offer significant weight savings in comparison to SLA parts. Because support structure is not required, assemblies and very complex large geometries can be created.
