An overview of functionally graded additive manufacturing
TLDR
Functionally Graded Additive Manufacturing (FGAM) is a layer-by-layer fabrication process that involves gradationally varying the material organization within a component to achieve an intended function as mentioned in this paper.Abstract:
Functionally Graded Additive Manufacturing (FGAM) is a layer-by-layer fabrication process that involves gradationally varying the material organisation within a component to achieve an intended function. FGAM establishes a radical shift from contour modelling to performance modelling by having the performance-driven functionality built directly into the material. FGAM can strategically control the density and porosity of the composition or can combine distinct materials to produce a seamless monolithic structure. This paper presents a state-of-art conceptual understanding of FGAM, covering an overview of current techniques that can enable the production of FGAM parts as well as identify current technological limitations and challenges. The possible strategies for overcoming those barriers are presented and recommendations on future design opportunities are discussed.read more

TL;DR: Additive manufacturing (AM) is fundamentally different from traditional formative or subtractive manufacturing in that it is the closest to the bottom-up manufacturing where a structure can be built into its designed shape using a "layer-by-layer" approach rather than casting or forming by technologies such as forging or machining as discussed by the authors.
