3-D printing as emerging technology-A review

3D printing is an emerging technology all over the world. It booms the industrial growth in many sectors like biomedical, Automation and Aeronautics, Construction, Food Processing and in Defence. Additive manufacturing is the “process of joining materials to make objects from 3D model data, usually layer by layer, as opposed to subtractive manufacturing methods. Synonyms include additive fabrication, additive processes, additive techniques, additive layer manufacturing, and additive fabrication.”3D printing, according to Wohler Report 2014: 13, is the “fabrication of objects through the deposition of a material using a print head, nozzle, or other printer technology. However, the term is often used synonymously with additive manufacturing. It particular it is associated with machines that are lower in price and overall functional capability.”

The modelis created with Computer aided design software, which make objects layer by layer of material under control. It's easy to operate and cover less space, all these properties make 3D Printing best for all. It change the definition of Manufacturing and easily accepted from child to adult to make their own dream product. Many free software are available in the Internet like FreeCAD, Cura, Blender etc from beginner to professional level which gives guidance of designing. This paper Reviews about 3D printing as emerging technology. This paper shows about the trigger of Next Industrial Revolution which set to have a transformational impact on the direct or indirect production of a reasonable proportion of products. This paper reviews 3-d printing as an operation and throws some insight on the various possible applications of it.
