Scope Objective: This symposium will provide a forum for all veins of additive manufacturing to present their latest results in developing methodology for science-based or practice-based material and process qualification. Sessions will be included that seek to develop processing-microstructure-property- performance relationships in metals and non-metals alike. Experimental, modeling, and combined experimental/modeling approaches are welcome.

Background and Rationale: Additive manufacturing (AM) offers distinct advantages over conventional manufacturing processes including the capability to both build and repair complex part shapes; to integrate and consolidate parts and thus overcome joining concerns; and to locally tailor material compositions as well as properties. A variety of fields such as aerospace, military, automotive, and biomedical are employing this manufacturing technique as a way to decrease costs, increase manufacturing agility, and explore novel geometry/functionalities. To increase acceptance of AM as a viable processing method, pathways for qualifying both the material and the process need to be developed and, perhaps, standardized. This symposium will serve as a venue for the international AM community - including government, academia, and industry - to define the fundamental interrelationships between feedstock, processing, microstructure, shape, mechanical behavior/materials properties, and function/performance. This will be accomplished through experimental observations, theoretical advances, and computational modeling of physical processes to provide insight and understanding of the nature of the final product and the evolution of microstructure resulting in final part properties and performance.

Materials of interest include but are not limited to:
• Homogeneous materials: polymers, ceramics, and metals
• Heterogeneous materials: foams, polymeric matrix, metallic matrix, ceramic matrix, functionally graded

Areas of interest include, but are not limited to:
• Fabrication:
o Machines: emerging technologies and advancing current capabilities
o Processing: feedstock material (including powder, wire, and filament), process and process monitoring (both freeform and direct write), build parameters, repair parameters, post processing (e.g., heat treatment)
o Specimen design: net-shaped parts; parts machined to shape based on scaling; as built laboratory test specimens/coupons; specimens/coupons machined from larger builds
• Developing constitutive relationships: coupling microstructure measurements and experimental stress analysis to characterize mechanical behavior/materials properties targeting performance
• Closing the feedback loop: microstructure measurements feedback to fabrication; performance (mechanical behavior, materials properties, and/or functional) feedback to fabrication
