Building a conceptual understanding of Functionally Graded Additive Manufacturing (original) (raw)

Technological progress in Additive Manufacturing (AM) hardware, software, as well as the opening of new markets and applications has encouraged research into novel materials with functionally graded and high performance capabilities. Functionally Graded Additive Manufacturing (FGAM) is a layer-by-layer fabrication technique that gradationally varies the ratio of the material organization within a component to achieve an intended function. As research in this field has gained worldwide interest, the interpretations of the FGAM concept requires greater clarification. The objective of this paper is to present a conceptual understanding of FGAM by clarifying key terms associated with FGAM. The current stateof-the-art and capabilities of FGAM technology are reviewed alongside with current technological obstacles and limitations, followed by recommendations on possible strategies to overcome those barriers for FGAM to take off.
