Additive manufacturing - Design - Functionally graded additive manufacturing (ISO/ASTM/TR 52912:2020)

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 requires greater clarification. The objective of this document is to present a conceptual understanding of FGAM. The current-state of art and capabilities of FGAM technology will be reviewed alongside with its challenging technological obstacles 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 directions for FGAM to take off.

Fabrication additive - Conception - Fabrication additive à gradient fonctionnel (ISO/ASTM/TR 52912:2020)

L'utilisation de la fabrication additive (FA) permet la fabrication de composants géométriquement complexes en déposant des matériaux avec exactitude et de manière contrôlée. Les progrès technologiques dans le domaine du matériel, des logiciels de FA, ainsi que l'ouverture de nouveaux marchés exigent une plus grande flexibilité et une plus grande efficacité des produits actuels, ce qui encourage la recherche de matériaux nouveaux dotés de capacités à gradient fonctionnel et de hautes performances. Cela a été désigné par la fabrication additive à gradient fonctionnel (FGAM), une technique de fabrication couche par couche qui consiste à faire varier graduellement le rapport de l'organisation du matériau au sein d'un composant pour répondre à une fonction prévue. Comme la recherche dans ce domaine a gagné en intérêt dans le monde entier, les interprétations du concept de FGAM exigent une plus grande clarification. L'objectif du présent document est de présenter une compréhension conceptuelle de la FGAM. L'État de l'Art actuel et les capacités actuelles de la technologie de FGAM seront examinés, ainsi que ses obstacles et limites technologiques. Les formats d'échange de données et certaines applications récentes sont ici évalués, suivis de recommandations sur les stratégies possibles pour surmonter les obstacles et les orientations futures pour le décollage de la FGAM.
