Selective Laser Sintering (SLS) is a Rapid Prototyping technique in which a three-dimensional object is fabricated by applying successive layers of powder each of them is sintered and bonded to the preceding layer by local heating generated by a laser beam.
Sintering is a method involving consolidation of powder grains by heating the “green” compact part to a high temperature below the melting point, when the material of the separate particles diffuse to the neighboring powder particles.
Selective Laser Sintering is used for fabrication of parts from polymer, ceramic and metallic powders.
