Patent number: 11077610Abstract: Method for additive manufacturing of at least one component comprises the manufacture, by depositing and selective melting of layers of powder, of at least one intermediate assembly comprising the component produced at an inclined angle and forming an angle of between 20° and 70° with a manufacturing support plate, a support interposed between the support plate and a lower base of the component, and at least one local supporting element resting against the rear frontal face of the component. During the selective-melting phases of the manufacturing step, incipient cracks are formed in regions of connection of the support and of the supporting element to the component. The component is separated from the support and the local supporting element after the manufacturing step by breaking of the connecting regions.Type: GrantFiled: November 3, 2016Date of Patent: August 3, 2021Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Etienne Blanchet, Romain Calvel, Florian Eparvier

Patent number: 10583481Abstract: A part obtained by selective melting of a powder on a support plate, this part comprising a main element and rigid secondary elements, these secondary elements supporting the main element between a lower surface of this main element and the support plate. Secondary elements are intended to be detached from the main element. The lower surface of the main element thus comprises a first surface portion and at least one second surface portion, and the first surface portion makes, with the support plate, an angle ?1 of less than a predetermined value, and the second surface portion makes, with this support plate, an angle ?2 greater than or equal to this predetermined value. The first surface portion is therefore entirely supported by the secondary elements and the second surface portion is partially supported by the secondary elements. The predetermined value is between 20° and 30°.Type: GrantFiled: February 12, 2014Date of Patent: March 10, 2020Assignees: Compagnie Generale Des Etablissements Michelin, Michelin Recherche Et Technique, S.A.Inventor: Etienne Blanchet
