thermal activation of the particles to be sintered takes place. (- The'particles lie looSely in the powder bed. They are made molten on the surface locally. (selective) by a laser beam and thereby joined to a layer. in fact this is a partial melting and solidification process known as liquid sintering or (selective) laser sintering.
A CO2 laser is used to melt polymeric powder and form part geometries without using any toxic chemicals, blowing agents or support structures. SLS materials are suited for direct functional applications where robust performance characteristics are required [1] . 3D objects are fabricated by selectively sintering the
INTRODUCTION. Selective laser sintering (SLS) is an intelligent manufacturing process based on the use of powder- coated metal additives, a process generally used for rapid prototyping and instrumentation. A continuous. Laser beams are used or pulsating as heating source for scanning and aligning particles in
Selective Laser Sintering (SLS) is a rapid prototyping and manufacturing process that sinters (fuses) a variety of nylon-based materials for quick-turn models or for short-run production. SLS_inner3.

11 Mar 2016 A Review on Selective Laser Sintering: A Rapid Prototyping. Technology. K.R. Bakshi, A. V. Mulay. (Department of Production and Industrial Engineering, College Of Engineering, Pune, India). Abstract: The components which were assumed to be very difficult to produce or manufacture some years ago.
Abstract. Layer Manufacturing (LM) technologies like Selective Laser Sintering (SLS) were developed in the late 80's as techniques for Rapid Prototyping (RP). Today, SLS - as well as its derived technology Selective Laser Melting (SLM) - is used as well for prototyping, tooling and manufacturing purposes. This widening of
Direct Laser Sintering of Metals. William T. Carter, Jr. and Marshall G. Jones. General Electric. Corporate Research & Developlnent Center. Abstract. The use of a directed laser bealn source to selectively sinter multiple layers of binderless metal powder for the purposes of rapid prototyping is described. The work in this
This article presents an overview of selective laser sintering (SLS) work as reported in various journals and proceedings. Selective laser sintering was first done mainly on polymers and nylon to create prototypes for audio-visual help and fit-to-form tests. Gradually it was expanded to include metals and alloys to manufacture.
2 Nov 2010 The Selective laser sintering process can be indirect or direct: 1. The indirect SLS uses a polymer coating of about 5 µm in thickness for metal powders and ceramics. The metal powder particles are coated with the polymer and the action of the laser melts the polymer, bonding the metal particles together to
5 May 2015 aided design (CAD) model. The Additive manufacturing method can produce fully dense metal parts in a short time, with higher precision. Selective Laser Sintering (SLS) technique uses powder bed fusion, in which each powder bed layer is selectively fused by using a laser or electron beam, as an energy.
