Method for manufacturing an asymmetric component using additive manufacturing

Method for manufacturing a component using additive manufacturing, notably by fusing or sintering particles of powder using a high-energy beam. According to the invention, this method comprises the following steps: provision of a digital model of a component that is to be manufactured, orientation of the model with respect to a direction of construction (62) of the component, modification of the model by adding a sacrificial equalizing portion (72) configured to equalize the residual stresses that are introduced into the component while same is being manufactured, creation of a raw component layer by layer using an additive manufacturing technique based on the model thus modified (50'), said layers being stacked in the direction of construction (62), removal of the sacrificial part from the raw component derived from the sacrificial equalizing portion (72) of the model (50') using a method involving the removal of material therefrom, thereby obtaining said component that is to be manufactured.
