Selective Laser Sintering (SLS) is a process by which 3D (Three Dimensional) prototypes are created by fusing or sintering powdered thermoplastic materials or metals to form functional prototypes. SLS uses a range of materials which includes nylon, metals, and elastomers. Rapid prototype (RP) laser sintering can provide a competitive edge in your product development by producing rapid plastic or metal SLS prototypes with complex shapes that closely resemble injection-molded parts.

The Selective Laser Sintering (SLS) process creates three-dimensional parts by fusing powdered thermoplastic materials with the heat from an infrared laser beam. The process is repeated over and again by fusing thin powder layers through a laser beam till the object is created. This additive manufacturing sequence produces parts that gradually increase in size until they reach the given dimensions. The prototypes are created directly from 3D CAD (Computer Aided Designs) models. There is considerable progress over the years in improving surface finish and porosity of objects created through this technique. The method has also been extended to provide direct fabrication of metal and ceramic objects and tools.

SLS has the potential to make metal prototype parts using the Rapid Steel A6 or Laser Form ST-200 materials, where metallic powder is used in the laser sintering process. Selective laser sintering material is ideal for bellows and gaskets. Another advantage is that there is typically very little processing required after the selective laser sintering is completed. It is customized allowing design changes to be made without having to create a new tool. The parts or assemblies formed have a good surface finish and feature detail. It gives the capability of flexible snaps and living hinges as well as high stress and heat tolerance. There is rapid delivery of parts or patterns with in a short span of time giving space for marketing.
