The use of Additive Manufacturing (AM) enables the fabrication of geometrically complex componentsby accurately depositing materials in a controlled way. Technological progress in AM hardware,software, as well as the opening of new markets demand for higher flexibility and greater efficiencyin today's products, encouraging research into novel materials with functionally graded and highperformancecapabilities. This has been termed as Functionally Graded Additive Manufacturing(FGAM), a layer-by-layer fabrication technique that involves gradationally varying the ratio of thematerial organization within a component to meet an intended function. As research in this field hasgained worldwide interest, the interpretations of the FGAM concept requires greater clarification.The objective of this document is to present a conceptual understanding of FGAM. The current-state ofart and capabilities of FGAM technology will be reviewed alongside with its challenging technologicalobstacles and limitations. Here, data exchange formats and some of the recent application is evaluated,followed with recommendations on possible strategies in overcoming barriers and future directionsfor FGAM to take off.
