Title (EN) ADDITIVE MANUFACTURING
(FR) FABRICATION ADDITIVE
Abstract:
(EN) A method of additive manufacturing metallic components, the method comprising the steps of: forming a component in a layer by layer process, the component being formed integrally with at least one non-perforated support structure to be separated from the component after the layer by layer process, the support structure being formed with at least one wall that is non- perforated; and wherein after completion of the layer by layer process, the method comprises exposing the component and support structure to at least one thermal pulse so as to weaken, or break, the interface(s) between the support structure and component prior to removal of the support.
(FR) La présente invention concerne un procédé de fabrication additive de composants métalliques, le procédé comprenant les étapes de: formation d'un composant dans un processus couche par couche, le composant étant formé de façon intégrée avec au moins une structure de support non perforée devant être séparée du composant après le processus de couche par couche, la structure de support étant formée avec au moins une paroi qui n'est pas perforée; et dans lequel, après l'achèvement du processus couche par couche, le procédé comprend l'exposition du composant et de la structure de support à au moins une impulsion thermique de façon à affaiblir ou à rompre la ou les interface(s) entre la structure de support et le composant avant le retrait du support.
