What is PD CEN/TR/ISO/ASTM 52912 about?
The use of Additive Manufacturing (AM) enables the fabrication of geometrically complex components by 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 efficiency in today’s products, encouraging research into novel materials with functionally graded and high-performance capabilities. This has been termed as Functionally Graded Additive Manufacturing (FGAM), a layer-by-layer fabrication technique that involves gradationally varying the ratio of the material organization within a component to meet an intended function. As research in this field has gained worldwide interest, the interpretations of the FGAM concept require greater clarification.
The objective of PD CEN/TR/ISO/ASTM 52912 is to present a conceptual understanding of FGAM. The current state of art and capabilities of FGAM technology will be reviewed alongside its challenging technological obstacles and limitations. Here, data exchange formats and some of the recent application is evaluated, followed by recommendations on possible strategies in overcoming barriers and future directions for FGAM to take off.

Why should you use PD CEN/TR/ISO/ASTM 52912?
Functionally Graded Materials (FGMs) are a class of advanced materials with spatially varying composition over a changing dimension, with corresponding changes in material properties built in. FGMs attain their multifunctional status by mapping performance requirements to strategies of material structuring and allocation.
The manufacturing processes of conventional FGMs include shot peening, ion implantation, thermal spraying, electrophoretic deposition and chemical vapour deposition. Since additive manufacturing processes builds parts by successive addition of material, they provide the possibility to produce products with Functionally Graded properties, thereby introducing the concept often known as Functionally Graded Additive Manufacturing (FGAM). As this area of work is new, driven by academic research, and lacks available standardization, there have been multiple different names proposed by different researchers in different publications as terms for this area, for example, functionally graded rapid prototyping (FGRP), varied property rapid prototyping (VPRP) and site-specific properties additive manufacturing.
