Selective Laser Sintering technology uses a laser to harden and bond small grains of plastic, ceramic, glass, metal, or other materials into layers that form a 3D dimensional structure. The laser traces the pattern of each cross section of the 3D design onto a bed of powder. After one layer is built, the bed lowers and another layer is built on top of the previous layer until the part is complete. SLS doesn’t require the support structures that many other technologies use to prevent the design from collapsing during production. This characteristic alone, while also conserving materials, means that SLS is capable of producing complex geometries unlike any other technology.
