Aspects of the disclosure relate to apparatus and methods for producing a downhole electrical component, having steps of providing a non-conductive polymer substrate, establishing an active area on the non-conductive polymer substrate, patterning the active area on the non-conductive polymer substrate with a conductive material through an additive manufacturing process and incorporating the patterned non-conductive polymer substrate into a final arrangement.

A tooling assembly for mounting a plurality of components, such as compressor blades, in a powder bed additive manufacturing machine to facilitate a repair process is provided. The tooling assembly includes component fixtures configured for receiving each of the compressor blades, a mounting plate for receiving the component fixtures, and a magnet assembly operably coupling the component fixtures to the mounting plate in a desired position and orientation to facilitate an improved printing process.

A meshed shell and a sandblasting method are provided. The meshed shell includes a first end portion, a second end portion opposite to the first end portion, a first annular portion, a second annular portion connected to the first annular portion, a first mesh portion between the first end portion and the first annular portion and a second mesh portion between the second end portion and the second annular portion. The weights of the first end portion and the second end portion are the same. A maximum inner diameter of the mesh of the first and second mesh portions is smaller than a penetration size of the component. Both of the sum of the weights of the first and second end portions and the sum of the weights of the first and second annular portions are greater than the sum of the weights of the first and second mesh portions.

According to examples, a processor may dilate a first digital model of a first 3D part a predefined amount and a second digital model of a second 3D part the predefined amount, in which the first 3D part and the second 3D part are to be fabricated together in an assembly to have a functional relationship with respect to each other, and in which the first digital model and the second digital model are spaced from each other in a manner that corresponds to a spacing of the first 3D part and the second 3D part in the assembly. The processor may determine a spatial relationship between the dilated first digital model and the dilated second digital model and may determine, based on the determined spatial relationship, whether the assembly of the first 3D part and the second 3D part is predicted to function properly when the assembly is fabricated.

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.

A method for joining an additively-manufactured component includes welding a plurality of additively-manufactured components via a weld joint to fabricate an integral structure. The additively-manufactured components are built by repeatedly depositing a weld bead layer of a next layer on a weld bead layer formed of a weld bead obtained by melting and solidifying a filler metal by use of an arc, and the weld joint is built along with the deposition.
