Science, Technology and Applications of Metals in Additive Manufacturing

Bhaskar Dutta, Ph.D. has over 26 years of experience in the field of metallurgy and metal processing, including 11 years in the Additive Manufacturing (AM) industry. He has been directly involved in participating and directing AM research and technology development as well as commercial product development using AM. He has over 15 publications and more than 30 presentations in the field of AM. He also has 7 pending patents in this area.Dr. Sudarsanam Babu is the UT/ORNL Governor's chair of advanced manufacturing at the University of Tennessee, Knoxville, TN. In this role he acts as a bridge to the ORNL's expertise and infrastructure including manufacturing demonstration facility to develop a collaborative research and education ecosystem locally and deploy engineering solutions to manufacturing industries. Dr. Babu has 23 years of experience in the area of advanced manufacturing, additive manufacturing, physical metallurgy, as well as, computational materials modeling. His work relates to welding metallurgy, solid-state joining, ultrasonic additive manufacturing, laser/electron beam assisted additive manufacturing, phase transformation issues related to low-alloy steels, inclusion formation, nonequilibrium solidification, and application of computational thermodynamics and kinetics to corrosion issues. He is also involved in the application of state-of-the-art characterization tools including atom probe tomography; synchrotron diffraction and neutron diffraction for understanding interaction between weld thermal cycles, phase stability and diffusion in complex alloys, as well as, energy storage materials. Dr. Babu has published 180 journal papers and numerous conference proceedings. He has received many awards in recognition of his technical and leadership service to the materials and manufacturing community. He is a fellow of AAAS, ASM International and AWS.Dr. Bradley H. Jared is a Principal Member of the Technical Staff at Sandia National Laboratories where he leads research and development efforts in advanced and additive manufacturing within the Materials Science and Engineering Center. He has over 20 years of experience in mechanical design and advanced manufacturing process development including precision machining, metrology, ultrafast pulsed laser processing and additive manufacturing. He is working with multiple Sandia teams evaluating the requirements and design aspects for qualification of additive components, materials and processes for high consequence applications. His additive research interests are focused on process-structure-property relationships in metal powder bed fusion, the metrology of additive equipment and processes, the application of advanced optimization design methodologies, and the development of computational tools for predicting material and process performance. Bradley has over 15 years of research experience and worked in the industrial sector for Corning Incorporated and 3M before joining Sandia working in precision fabrication, design and assembly. He has submitted over 15 technical advances for intellectual property at Sandia, three of which have accepted for patents.
