Abstract

La présente invention concerne un procédé de fabrication additive d'une ébauche d'un objet métallique à partir d'un objet numérique, par apport de matière métallique sur un support lui-même métallique, combiné à un apport d'énergie. On réalise l'apport de matière métallique sous forme de plusieurs éléments de surface discrets (1, 1', 2), l'apport d'énergie permettant de souder les éléments sur le support (3) en au moins deux passes à savoir une première passe et une deuxième passe, chaque élément de surface étant défini par une longueur (L, 1) selon laquelle il est soudé sur le support, une hauteur (h) selon laquelle il s'étend en saillie par rapport au support après avoir été soudé sur celui-ci , et une épaisseur (e) dans un plan sensiblement perpendiculaire à celui défini par la hauteur (h) et la longueur (L, 1) de l'élément, la hauteur de l'élément étant supérieure à son épaisseur, le procédé comportant une étape d'enlèvement de matière réalisée à sec d'au moins un des éléments de la première passe avant réalisation de la deuxième passe.The present invention relates to a process for the additive manufacturing of a blank of a metallic object from a digital object, by supplying metallic material on a support which is itself metallic, combined with an input of energy. The supply of metallic material is carried out in the form of several discrete surface elements (1, 1 ', 2), the energy supply making it possible to weld the elements on the support (3) in at least two passes, namely one first pass and a second pass, each surface element being defined by a length (L, 1) according to which it is welded to the support, a height (h) according to which it protrudes from the support after having been welded thereon, and a thickness (e) in a plane substantially perpendicular to that defined by the height (h) and the length (L, 1) of the element, the height of the element being greater than its thickness , the method comprising a step of removing material carried out dry from at least one of the elements of the first pass before carrying out the second pass.
