"Putting More Refractory Metals in Additive Manufacturing"
The use of refractory metal elements, either by additively manufacturing (AM) their alloys or by including them in other alloys, has always been a challenge due to their high melting temperatures, oxygen affinity, and brittle-ductile transition temperatures. These factors make them more susceptible to defect formation, in particular cracking during deposition. In this talk, an overview of the challenges associated with using refractory metals in creating functionally graded structures using direct energy deposition and laser powder bed fusion will be explored. Additional case studies will also be discussed on AM of refractory metals and alloys, highlighting some strategies to reduce their defect formation susceptibility.

"Novel Applications with Directed Energy Deposition (DED)"
About the Presentation
Directed Energy Deposition (DED) as an AM technology enables novel applications from new alloy development to functionally graded materials (FGM) and large-scale manufacturing. DED offers unique capabilities in materials due to its ability to use multiple materials within the same build, and low material consumption. Computational design frameworks can rapidly generate many compositional architectures for alloy design and transitions and bridging the gap between the computational and physical samples is key to rapid development. FormAlloy’s Co-Founder & CEO, Melanie Lang, will provide insight into the design and development of state-of-the-art DED systems and the Alloy Development Feeder (ADF), and share examples of how novel applications and rapid development are enabled by DED and the associated data capture framework known as DEDSmart™.

"Overview of Research to Standardization Efforts in Support of Additive Manufacturing Qualification and Certification"
About the Presentation
Ensuring the quality of additively manufactured parts and components is extremely critical as AM technology adoption is becoming faster across multiple industry sectors. In the past couple of years, many international standards have been published that can be used to develop quality assurance framework within an organization in order to achieve third-party or regulatory certification. This presentation provides an overview of the needs and importance of research to standardization in delivering quality AM products. Many existing standards can be mapped to the AM process chain for qualification while many gaps already exist in AM standardization. The major role of research community in closing the gaps and AM industrialization will be also highlighted.
About the Presenter

"TMS Young Innovator in the Materials Science of Additive Manufacturing Award: Microstructure Design Freedom in Metal AM: A LEGO® Analogy"
About the Presentation
Since its inception, additive manufacturing (AM) has been synonymous with geometric design freedom. However, the disruptive potential of AM goes beyond the fabrication of parts with complex shape. By employing variable processing parameters during AM, it is possible to control the formation of dissimilar microstructures within the same build. This capability enables novel materials designs by arranging the attainable microstructures into complex architectures as if they were pieces of a LEGO® construction set. In this talk, different AM strategies will be presented that demonstrate this “microstructure design freedom.” This presentation will also describe the unique functionalities imparted by some of these microstructure architectures and discuss future opportunities to leverage the combined geometric and microstructure design freedom to produce engineering alloys with improved performance.
About the Presenter
Matteo Seita is the Granta Design Assistant Professor in the Department of Engineering at the University of Cambridge, where he leads the Additive Microstructure Engineering Laboratory (AddME Lab). The goal of the AddME Lab is to understand and control the microstructure complexity brought about by additive manufacturing processes to design metallic materials with improved performance and novel functionalities. Before joining the University of Cambridge, Seita was a Nanyang Assistant Professor at NTU Singapore. During his tenure at NTU, he was awarded the prestigious NRF Fellowship—a S$3M individual grant for early-career scientists—to develop novel additive manufacturing strategies for microstructure control of metal alloys. He earned his Ph.D. in Materials Science from ETH Zurich in 2012 and then spent three years as a postdoctoral associate in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology.
