Study on the Selective Laser Sintering In Additive Manufacturing

Abstract

Additive manufacturing process, also popularly known as 3-D printing, is a process where a product is created in a succession of layers. Selective laser sintering (SLS) is one of the additive manufacturing technologies, which is used in the sintering process of powder metallurgical product. During SLS, tiny particles of plastic, ceramic or glass are fused together by heat from a high power laser to form a solid , three - dimensional product .The product printed with an SLS machine starts with CAD files which is converted to .STL format . Unlike other methods of 3D printing, SLS doesn't require the use of additional supports to hold an object together while it is being printed. The complexity factor of this process is almost 0% as in any shape and size can be manufactured except hollow enclosed shape.
