Hugo SISTACH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12269094
    Abstract: A method for manufacturing an aeronautical part utilizes injection molding. After injecting the prepared mixtures to obtain two green blanks, an assembly area of at least one of these two blanks is heated. The blanks are assembled and then debinding is carried out. A sintering treatment is then carried out.

  • Publication number: 20240278327
    Abstract: A device for additive manufacturing by powder bed fusion includes an enclosure having, in a lower portion of the enclosure, a manufacturing platform and a powder spreading means adapted to travel over the manufacturing platform in order to spread powder previously deposited on the manufacturing platform. The enclosure further includes, in an upper portion, a window facing the manufacturing platform and allowing the passage of laser beams. The device has at least one effector arranged in the enclosure and connected to at least two actuators, which are configured to move the effector between the upper portion of the enclosure and a target position on the manufacturing platform.

  • Patent number: 11826819
    Abstract: A process manufactures a metal part for a turbomachine that includes first and second metal materials with different chemical compositions. The process includes the steps of obtaining an element of which at least a first metallic part is made of the first metallic material and placing the element in a first mold and pouring wax into the mold to at least partially cover the element. The first mold has an impression corresponding to at least part of an external surface of the metal part. The process further includes obtaining an assembly by removing the first mold and making a shell mold with a first ceramic around the assembly. The process also includes removing the wax from the shell mold and pouring the second metal material into the shell mold in place of the wax, and removing any ceramics present in the assembly.

  • Publication number: 20220258235
    Abstract: A method for manufacturing a metal part includes forming by additive manufacturing a blank of a first portion of the part to be manufactured including a first binder and a first metal powder present in the first binder, forming by injection molding a blank of a second portion of the part to be manufactured including a second binder and a second metal powder in the second binder, debinding the blank of the first portion and the blank of the second portion, and joint sintering of the first debound blank and of the second debound blank to obtain the part, the first and the second blanks being in contact during sintering.

  • Publication number: 20220234107
    Abstract: A method for additive manufacturing deposits material on a part forming a substrate, wherein the part forming a substrate is made of a metal alloy. The method includes a step of low-energy deposition corresponding to a surface energy of less than 400 J/mm2, on a predefined surface to be deposited, in order to form a base layer. The method further includes a step of high-energy deposition, corresponding to a surface energy greater than 500 J/mm2, by depositing a wire on the base layer already formed.

  • Publication number: 20220143758
    Abstract: A method for treating an internal defect in a part made of a material, involves: a) detecting and locating the internal defect in the part; b) defining, inside the part, at least one target volume which at least partially includes the defect; c) for each target volume, simultaneously irradiating the target volume by at least two beams which converge in the target volume and are continuous, whereby a treated area is obtained. The energy applied to the target volume by each beam is less than a threshold energy for sintering the material, and the sum of the energies applied to the target volume by each of the beams is greater than or equal to a transformation threshold energy that corresponds to the threshold energy for sintering or melting the material; the material of the part is partially transparent to said beams.
