Selective Laser Sintering

Selective laser sintering (SLS) is considered an additive rapid prototyping technique that utilizes a high power laser to fuse particles of plastic, metal, or ceramic powders into a 3-dimensional object. The laser fuses powdered material by scanning cross-sections generated from a 3-D digital model from a CAD file or scan data on a powder bed. After each individual cross-section is scanned, the bed is lowered slightly and a new layer of material is applied on top. The process is repeated until the part is completed.
SLS can produce parts from a wide range of powder materials including polymers , metals and sand. The materials can be fully melted, partial melting, or liquid-phase sintered.
SLS is performed by machines called SLS systems. The most widely known model of SLS systems is the Sinterstation SLS system.
