Scope Additive manufacturing is a fast-developing eco-friendly fabrication pathway that allows engineers to design a single part rather than multiple individual parts, reducing the procedures of joining or assembly compared to the traditional manufacturing methods. AM also provides a tremendous opportunity to synergistically couple materials, design and manufacturing strategies, where one can strive towards fabricating parts with targeted site-specific properties. For example, a combinatorial approach for zone-based hybrid microstructural evolution may be achieved by employing multi-material alloying and multi-modal manufacturing strategies. Other examples include overcoming mismatches in thermal expansion coefficients, controlling residual stress and/or achieving desirable microstructure in heat treated multi-material builds.

The purpose of this symposium is to present the latest developments that explore and possibly integrate the following breakthrough AM functionalities:
• Functionally Graded Materials: use of multi-material builds via sequential or simultaneous injection of raw materials, or single material with dramatically different process conditions for tailored hybrid microstructures
• Metamaterials: topological and/or shape optimization to exploit light-weighting and enhanced property response
• Multimodal Manufacturing: integrating additive and/or conventional manufacturing techniques to achieve the right balance among materials properties, part resolution and build efficiency

The call encompasses all AM modalities, such as the Laser or E-Beam based PBF and DED processes. Studies on processing-structure-property assessments of structural and functional materials by coupling multiscale experimental and modeling strategies are encouraged.
