Title (EN) FEEDSTOCKS FOR ADDITIVE MANUFACTURING, AND METHODS OF USING THE SAME
(FR) CHARGES D'ALIMENTATION POUR FABRICATION ADDITIVE, ET LEURS PROCÉDÉS D'UTILISATION
Abstract:
(EN) Some variations provide a method of making an additively manufactured metal component, comprising: providing a feedstock that includes a high-vapor-pressure metal; exposing a first amount of the feedstock to an energy source for melting; and solidifying the melt layer, thereby generating a solid layer of an additively manufactured metal component. The metal-containing feedstock is enriched with a higher concentration of the high-vapor-pressure metal compared to its concentration in the additively manufactured metal component. The high-vaporpressure metal may be selected from Mg, Zn, Li, Al, Cd, Hg, K, Na, Rb, Cs, Mn, Be, Ca, Sr, or Ba, for example. Additively manufactured metal components are provided. Metal-containing feedstocks for additive manufacturing are also disclosed, wherein concentration of at least one high-vapor-pressure metal in the feedstock is selected based on a desired concentration of the high-vapor-pressure metal in an additively manufactured metal component derived from the metal-containing feedstock. Various feedstock compositions are disclosed.
(FR) Certaines variantes concernent un procédé de fabrication d'un composant métallique fabriqué de manière additive, consistant à : fournir une charge d'alimentation qui comprend un métal à haute pression de vapeur ; exposer une première quantité de la charge d'alimentation à une source d'énergie pour la fusion ; et solidifier la couche fondue, ce qui permet de produire une couche solide d'un composant métallique fabriqué de manière additive. La charge d'alimentation contenant du métal est enrichie avec une concentration plus élevée du métal à haute pression de vapeur par rapport à sa concentration dans le composant métallique fabriqué de manière additive. Le métal à haute pression de vapeur peut être choisi parmi Mg, Zn, Li, Al, Cd, Hg, K, Na, Rb, Cs, Mn, be, Ca, Sr ou Ba, par exemple. L'invention concerne également des composants métalliques fabriqués de manière additive. L'invention concerne également des charges d'alimentation contenant du métal pour la fabrication additive, la concentration d'au moins un métal à haute pression de vapeur dans la charge d'alimentation étant sélectionnée sur la base d'une concentration souhaitée du métal à haute pression de vapeur dans un composant métallique fabriqué de manière additive dérivé de la charge d'alimentation contenant du métal. L'invention porte également sur diverses compositions de charge d'alimentation.
