Large scale 3D printing – past, present and future prospects.
Since over two decades ago, when the speaker invented the Contour Crafting technology and started the development in the field of large scale 3D printing, no other activity in the field was initiated for over a decade. More recently the number of related developments have been almost exponentially increasingly. Technologies using various materials and various robotics approaches have been recently under development targeting a multitude of applications in the large scale domain. A historical perspective, a review of current activities and discussion of future prospects for terrestrial and planetary applications of large scale 3D printing will be presented.
Behrokh Khoshnevis is a Dean’s Professor of Industrial & Systems Engineering, Aerospace & Mechanical Engineering, Astronautics Engineering, Biomedical Engineering and Civil & Environmental Engineering and is the Director of the Center for Rapid Automated Fabrication Technologies (CRAFT). An inductee of the National Academy of Inventors, he is active in robotics, and mechatronics related research and development projects that include the development of three novel Additive Manufacturing (3D Printing) processes called Contour Crafting, SIS and SSS family of 3D Printing technologies as well as development of mechatronics systems for biomedical applications (e.g., digital restorative dentistry and orthodontics, rehabilitation engineering, and tactile sensing devices), autonomous mobile and modular robots for fabrication and assembly applications on Earth, in space and on other planets, planetary construction of human settlements, and energy systems including wind energy and energy storage technologies and automated production equipment for oil (petroleum) and gas industries. He has several major inventions which have been either commercialized or are in the commercialization process. His educational activities at USC include the teaching of a graduate course on Invention and Technology Development. He routinely conducts lectures and seminars on the subjects of creativity and invention. He is a NASA Innovative Advanced Concepts (NIAC) Fellow, a Fellow member of the Society for Computer Simulation, and a Fellow member of the Institute of Industrial Engineers. His inventions have received extensive worldwide publicity in acclaimed media such as New York Times, Los Angeles Times, Business Week, Der Spiegel, New Scientist, and numerous national and international television and radio networks. In 2014 Contour Crafting received the Grand Prize among 1000+ globally competing technologies in the Create the Future Design Contest which was organized by the NASA TechBriefs Group. Contour Crafting was earlier selected as one of the top 25 out of more than 4000 candidate inventions by the History Channel Modern Marvels program and the National Inventor’s Hall of Fame; and has been identified as one of the major disruptive technologies of our time. In 2016 the SSS Additive Manufacturing technology received the Grand Prize in the In-Situ Challenge international competition sponsored by NASA.

A Supply Chain Model for Additive Manufacturing: A Medical Case component
This presentation presents an exciting new topic for industrial/manufacturing engineering – using Additive Manufacturing (AM), or 3D Printing as it is commonly known in the press, to produce unique one-of-a-kind parts. Although AM has held the promise of making functional metal components directly from a CAD model in 1-2 days with very little human interactions, deficiencies associated with AM makes this vision difficult to achieve. For instance, parts coming from a metal AM process are typically the texture of a casting, meaning that they require finishing operations of some sort. This cast like surface also affects the mechanical properties of the component often leaving these parts with less than desired fatigue properties.
Richard Wysk’s research and teaching interests are in the general area of Computer Integrated Manufacturing (CIM) and medical device design and manufacturing. In particular, he is interested in: 1) lean manufacturing (waste elimination and setup reduction), 2) product/process engineering, 3) Computer-Aided Manufacturing, 4) Flexible Manufacturing Systems (FMSs) planning, design and control, and most recently 5) the engineering and manufacturing of medical products, including regenerative medical products.
Dr. Wysk has coauthored six books including Computer-Aided Manufacturing, with T.C. Chang and H.P. Wang — the 1991 IIE Book of the Year and the 1991 SME Eugene Merchant Book of the Year. He has also published more than one-hundred seventy-five technical papers in the open-literature in journals including the Transactions of ASME, the Transactions of IEEE and the IIE Transactions. He is an Associate Editor and/or a member of the Editorial Board for five technical journals.
Dr. Wysk is an IIE Fellow, an SME Fellow, a member of Sigma Xi, and a member of Alpha Pi Mu and Tau Beta Pi. He is the recipient of the IIE Region III Award for Excellence, the SME Outstanding Young Manufacturing Engineer Award, the IIE David F. Baker Distinguished Research Award and the IIE Albert Holzman Outstanding Educator Award.
He has held engineering positions with General Electric and Caterpillar Tractor Company. He has also served on the faculties of Virginia Polytechnic Institute and State University and Texas A&M University where he held the Royce Wisenbaker Chair in Innovation. He is a veteran of the U.S. Army, and served in Vietnam, where he earned a Bronze Star and an Army Commendation Medal with an Oak Leaf Cluster.
