This will be delivered in the form of a Technical Report. The aim of this document is to describe the concept of Functionally Graded Additive Manufacturing and to document current practices. It recognizes that Functionally Graded parts have the potential to support the development of Next-Generation products, based on the use of specialised materials that have been optimized for their functional properties. The report also clarifies the definitions of terms being used today such as 4D Printing (4DP), Smart Memory Polymers (SMP), Stimuli- Responsive Materials (SRM), Functionally Graded Materials (FGM), Multi-Material Printing (MMP), Variable Property Rapid Prototyping (VPRP), Self-Assembly and Self-Disassembly. The report outlines key manufacturing processes and examples of materials that have been used to produce FGM parts as well as their potential applications. The report will include a review of capabilities and limitations of existing CAD and Finite Element Method (FEM) software that can support the production of Functionally Graded Additive Manufactured parts. It discusses how existing software has been used to simulate FG materials that can have discrete or continuous variation of mechanical properties such as varying elastic modulus of the FGM piece. Finally, the report will discuss current limitations and suggests areas for future work.
