What Does Selective Laser Sintering Mean?

Selective laser sintering (SLS) is an additive manufacturing process that is used to build three-dimensional solid prototypes and components, usually of a small scale. It is a rapid prototyping technique that use laser to sinter powder-based materials into solid products and models. It was first conceived by Dr. Carl Deckard at the University of Texas.

Techopedia Explains Selective Laser Sintering

SLS use a a high-powered laser beam such as a carbon dioxide laser to join together raw materials and create the desired product/model. The material can be plastic, metal, glass or ceramic in a powdered form. The whole process of SLS is additive in nature. The laser beam takes cross section geometrical coordinates detail from a CAD drawing and adds the powder surface accordingly. When the layer is finished, the surface is powdered again and the process is repeated until the model is complete.
