A method of making hollow turbomachine components is disclosed. The method provides for an additive manufacturing step, wherein on a substrate the following are manufactured in sequence: a first terminal portion of a semi-finished component, said first terminal portion adhering to said substrate, an intermediate portion adjoining the first terminal portion, and a second terminal portion adjoining the intermediate portion. After cooling of the component, at least one of said first terminal portion and second terminal portion is removed. The removed terminal portion includes sacrificial features, where thermally induced deformations of the component are concentrated, or which are aimed at stiffening the component, such that deformations are reduced or prevented.
