Abstract

La présente invention concerne un procédé de renforcement d’une pièce (1) de tôlerie par apport local d’une matière de renfort sur au moins une face (1a) de cette pièce et sous forme d’une surépaisseur (2) de rigidification réalisée par impression 3D, caractérisé en ce qu’on réalise la surépaisseur (2) avec un profil au moins partiellement discontinu dans lequel sont ménagés des interstices (20), ainsi que la pièce renforcée obtenue.
