  • Bio

    Dr. C P Paul is leading a research group in area of Laser Additive Manufacturing (LAM) as Head, Laser Additive Manufacturing Laboratory at Raja Ramanna Centre for Advanced Technology (RRCAT). He has about 20 years of experience in research and development of LAM, from system development to its applications in engineering and prosthesis. His research programs focus on next generation additive manufacturing system and processes. To this end, his group explores novel techniques to develop advanced materials, innovative products, modeling and simulation tools, and holistic in-situ and ex-situ characterization techniques. He is instrumental in promoting LAM technology in India through collaborations with other national labs and reputed academic institutes by extending the indigenous developed facility for experiments.

    He has contributed chapters to eighteen books and published over 100 research papers. He is also authoring a text book on “Additive Manufacturing” for UG and PG Scholars to be published by McGrawHill Higher Education, which is expected to release by April 2021.

    Dr. Paul is also Dean-Student Affairs (RRCAT) at Homi Bhabha National Institute (HBNI) - a deemed to be University under Department of Atomic Energy (DAE), Government of India.

    His extensive experience and leadership have allowed him to address LAM challenges holistically and promoting this strategic research area. His efforts has been recognized and he is conferred with many national awards including highest DAE Excellence in Science, Technology and Engineering award "Homi Bhabha Science & Technology Award".


  • Abstract

    Additive Manufacturing (AM) is one of the disruptive technologies bringing a paradigm shift in design and manufacturing by facilitating the fabrication of new-to-market, mass customized and smarter products. AM is primarily different from conventional manufacturing as it allows to build a structure using a ‘layer-by-layer’ approach from a digital model. In conventional manufacturing route the product is made first, followed by its appreciation of novelty and lastly its sale to the customer. However, AM disrupts the conventional route by understanding the feel first through digitization followed by selling of product and finally its making. Realizing the potential and importance of AM, a comprehensive R&D program is undertaken since 2003 at Raja Ramanna Centre for Advanced Technology (RRCAT), India. The present chapter introduces AM followed by the various freedoms offered by AM, limitations, its need and evolution, and the global scenario. It will also include the classification of AM as per ASTM/ ISO 52900 explaining the process mechanisms, advantages, limitations and applications of the different technologies. It will also explain how AM contributes towards Industry 4.0. It will also discuss the development of indigenous AM technology and its deployment for various applications along with the future scope of the technology.
