    A Review on Materials and Working Process Parameters of Selective Laser Sintering
    (Journal of Polymer and Composites, 2025-03-12) Pandey, Rohit
    The potential for additive manufacturing technology to replace some of the current conventional manufacturing methods makes it one of the research and development fields that is expanding quickly. With additive manufacturing, three-dimensional physical models are produced layer by layer from computer-aided design (CAD) models. Fully dense metal things may be produced more rapidly and accurately with additive manufacturing. The Selective Laser Sintering (SLS) procedure uses powder bed fusion, in which each layer of the powder bed is precisely fused by an electron or laser beam. The additive manufacturing method has the most potential for generating smaller and medium-sized quantities of either simpler or more complex metal objects. The process parameters directly affect the amount of energy delivered to the thin layer’s surface and the energy density absorbed by the powders, which in turn determines the physical and mechanical properties of the built parts, such as relative density, porosity, surface roughness, dimensional accuracy, strength, etc. This analysis of the parameter-property connection is carried out for the most researched oxide ceramic materials, which include various ceramic mixtures and the alumina and silica families. One of those factors that is essential for improving ceramic quality is reducing temperature gradient, which minimizes thermal stress. The history, condition, and difficulties of the SLS Technique are discussed in this paper. The essay focuses on how the SLS technique handles metal materials. It also discusses the materials, equipment, and applications of the SLS processes, as well as their benefits and drawbacks.
