  • METHOD FOR THE ADDITIVE PRODUCTION OF AN ARTICLE
    Publication number: 20210269895
    Abstract: Method for the additive production of three-dimensional articles is disclosed. A powder layer of nickel-based metal alloy having a specific composition is scanned with an energy source so as to melt the powder in at least one point of the layer. Afterwards the energy source is removed from this point so as to solidify the metal alloy and form a layer with a desired shape. Also disclosed are articles obtainable by this method.
