Development of a new product involves carrying out a series of activities such as need analysis, ideation, conceptual design, preliminary design and detailed design, manufacturing, assembly, and testing. Conventionally, this chain of activities takes more time and hence considerable delay in launching the new product in the market. Rapid prototyping compresses the product development time which is vital for the survival of manufacturing industries. Reduced time-to-market greatly enhances the competitive advantage of industries. The book deals with various Rapid Prototyping Processes: Stereo-lithography, Selective Laser Sintering, Fusion Deposition, Modelling, Solid Ground Curing, Laminated Object Manufacturing, Vacuum Casting, 3D Printing, Rapid Tooling and Softwares for Rapid Prototyping, and Evaluative Questions. The book will be useful for those pursuing professional courses in design engineering, mechanical engineering, production engineering, and automobile engineering. It will also benefit manufacturing technology students studying in engineering colleges and institutes of technology.

Dr. M. Adithan, Professor Emeritus, Mechanical Engineering, VIT University, Vellore (Tamil Nadu), taught various manufacturing engineering related courses at IIT, Madras; National Institute of Technical Teachers Training and Research (NITTTR), Chandigarh; and VIT University, Vellore. He was a UNESCO Fellow at Ohio State University, U.S.A. and visiting Professor, University Technology, Malaysia. He was instrumental in establishing Rapid Prototyping Centre at VIT University.
