**Selective laser sintering** (**SLS**) is an [[additive manufacturing]] (AM) technique that uses a laser as the power and heat 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 but differ in technical details. Adapted from Wikipedia https://en.wikipedia.org/wiki/Selective_laser_sintering
