Abstract (en)

[origin: WO2022214399A1] The invention relates to a method for the additive manufacturing of a metal part (50) on a substrate (2), by adding at least one molten metal layer by layer. The method comprises the following steps: a) step a: depositing the molten metal layer by layer, b) step b: simultaneously with step a), cooling, by means of a cooler (7) that is mobile relative to the substrate (2), a cooling zone (8) located at least around the layer (n-1) deposited immediately prior to the layer currently being deposited (n).
