AM+EM+MS+TF-ThM-3 Additive Manufacturing Enabling Advanced Technologies
Teresa Clement (Raytheon Company)
The aerospace and defense industry for the last decade has taken note and contributed to significant advances in materials and process capabilities enabled by the field of additive manufacturing (AM) to fabricate beyond state-of-the-art advanced technologies. Conventional and non-conventional industry partners continue to push the boundaries of next-generation materials and multi-materials for additive manufacturing in order to further extend product capabilities. As these material developments continue evolving, our industrial base begins to realize the many benefits of AM: reducing lifecycle costs, engineering resilience and capability surprise by rapidly reconfigurable responses to adaptive adversarial threats, and the enabling of truly agile manufacturing via AM integration with the model based enterprise (aka marrying AM to the ‘digital thread’). Some specific examples of advanced technologies are discussed herein, with examples of design iteration cycle-time reduction and use of material/process controls to verify by inspection and full characterization demonstrations of improved or unprecedented material performance and multi-functionality (electrical, thermal, structural, etc) made possible by additive manufacturing.
AM+EM+MS+TF-ThM-5 4D Printing: Three Dimensional Printing with Material Composition as the Fourth Dimension
Douglas C. Hofmann (NASA Jet Propulsion Laboratory, California Institute of Technology)
Much of the current research in additive manufacturing in the aerospace community is focused on qualifying materials for service, which is a critical requirement for using additive materials. However, additive manufacturing is a powerful tool for creating materials and applications that cannot be replicated using traditional means. In the past, this has meant 3D printing complex geometries that cannot be easily machined. In the current talk, we will discuss what we call 4D printing; 3D printing where the fourth dimension is the material composition. By using multiple materials strategically in additive manufacturing, a whole new frontier of materials science becomes possible. The science behind these alloys and their applications will be discussed.

AM+EM+MS+TF-ThM-10 The Future of Additive Manufacturing and Multifunctional Parts
Phill Dickens (University of Nottingham, UK, United Kingdom of Great Britain and Northern Ireland)
Additive Manufacturing has many advantages for producing complex components and systems and this has already started to be exploited for parts made of a single material. There is now much interest in the possibility of building parts with multiple materials so that electrical circuits and electronic items can be included within the structure. This paper will highlight some of the research that is taking place at the University of Nottingham and some recent examples of simple products that could exploit this technology.
Some of the issues will be covered where the layer manufacturing process provides some limitations.
