Featured Speakers

Ming Leu, Missouri University of Science and Technology (MUST), USA
Presentation Title: "Additive Manufacturing Technologies, Applications, Markets and Opportunities"

Commonly known as 3D Printing, Additive Manufacturing (AM) is a suite of computer automated processes to fabricate three-dimensional physical objects layer by layer from CAD models. AM offers significant benefits over conventional manufacturing processes in producing one-of-a-kind parts or small batches, especially for those with geometric and/or material complexities. It holds great promise for the future as a tool-less, light-out manufacturing technology for components and products made of metals, polymers, ceramics and composites. This talk will first give an introduction of AM technologies along with their applications in the aerospace, healthcare, electronics and other industries. Then, markets and market trends on AM equipment, materials and services in the U.S. and abroad will be overviewed. Finally, future AM business and innovation opportunities will be presented.

Richard Hague, University of Nottingham, United Kingdom
Presentation Title: "Enabling Next Generation Additive Manufacturing: the 3D Deposition of Functional Materials for the Additive Manufacturing of Smart Devices - a UK perspective"

Though many of the emerging industrial examples of additive manufacturing are highly promising, by their single material nature, they also are limited to being used as “passive” entities that have little functionality beyond being structural. Taking the concept of design freedom beyond the geometrical domain to one where multiple materials are contemporaneously deposited opens-up the potential for the creation of complex, functionalized, “active” printed devices. However, though simple in concept, this discrete deposition of dissimilar materials throughout a 3D volume creates significant technical challenges, particularly in the deposition of useful materials.

This presentation will firstly give an overview of the UK AM landscape and then give a realistic view of the state of the art of “multifunctional” AM from both the UK and beyond. It will then focus on the current activities of the Centre for Additive Manufacturing (CfAM) at the University of Nottingham where a coordinate Programs of activity into next-generation, multifunctional AM is being undertaken. Principally funded by the UK’s national Science funder (EPSRC) and working with key industry, this research is predominantly, but not exclusively, utilizing novel jetting-based technologies for the co-deposition of both structural and functional materials for electronic, pharmaceutical and biological structures and devices over varying length scales.

About the Presenter: Richard Hague is Professor of Innovative Manufacturing and Director of the Centre for Additive Manufacturing (CfAM) at the University of Nottingham. Having worked in the AM field for over 24 years, he is internationally recognized both for scientific endeavor and creating impact though industrial exploitation where he has a background of leading and managing large multi-disciplinary, multi- partner research projects from both EPSRC and industry. Hague’s research interests are focused on AM specific processes, materials and computational methods across for wide spectrum of industrial sectors with current research programs focused on next generation multifunctional additive manufacturing. Richard has received multiple international awards and honors and is a co-founder and Director of Added Scientific Ltd, a spin out from the University of Nottingham focused on implementing Additive Manufacturing technical solutions to industry.

Todd Palmer, Pennsylvania State University, USA
Presentation Title: "Additive Manufacturing of Metals: Current Status and Future Outlook"

The Additive Manufacturing (AM) of metallic systems represents both great promise for the larger scale application of AM and challenges in producing structurally sound components with consistent material properties. The characteristic layer-by-layer deposition of the AM process produces complex processing conditions that can lead to unique microstructures and properties. In addition, it provides the opportunity to much more easily integrate different materials into complex geometries. Significant work is being undertaken globally on improving the process understanding as well as characterizing material properties in AM fabricated monolithic and functionally graded metallic components. Much of this future promise for AM processing of metals will depend on the development of new alloy systems and improved understanding and control of the processing conditions. Recent road mapping efforts have identified future directions for research in these areas, and progress on selected tasks will be reviewed.

Dave Rosen, Georgia Institute of Technology, USA/Singapore University of Design, Singapore
Presentation Title: "Polymers in Additive Manufacturing: Survey and Opportunities"

Despite the rapid growth of the Additive Manufacturing (AM) field, the range of polymer materials available for AM is far smaller than the breadth of polymers available for conventional manufacturing processes. This is due, in part, to the complexities of the coupled interacting physical and chemical phenomena occurring in AM processes. On the other hand, the unique capabilities of AM offer opportunities for developments of new polymer materials, composites, functionally graded materials, hierarchically structured materials, and others. In this talk, a survey is given of polymer materials and their AM processes. Opportunities for new polymer-based materials are identified and illustrated with recent research results.

Suman Das, Georgia Institute of Technology, USA
Presentation Title: "Additive Manufacturing of Ceramics"

Additive manufacturing of ceramics is an increasingly important area of research and development with applications spanning aerospace and defense, biotechnology, electronics, energy, metal casting, and several other sectors. A number of AM ceramics technologies were developed in the mid-1990s spurred by large US funding. These included, for example, robocasting, ceramic stereolithography, and ceramic slurry extrusion. In most cases, the processing was indirect and required thermal post-processing to eliminate transient binders and develop final properties. More recently, direct processing including laser sintering techniques have been developed. Several common direct and indirect ceramic AM methodologies will be presented in this talk. Emphasis will be placed on a novel technique developed by the presenter, Large Area Maskless Photopolymerization (LAMP). While broadly capable of a range of applications and ceramic systems, this approach is especially well-suited for printing high-precision ceramic cores and shell molds for investment casting of complex metal parts.

About the Presenter: Suman Das is the Morris M. Bryan, Jr. Chair in Mechanical Engineering for Advanced Manufacturing Systems, professor of mechanical engineering and of materials science and engineering at Georgia Tech.
