A composite member is manufactured by a manufacturing method including adding, on a surface of a base member composed of a first material, a second material different from the first material, using additive manufacturing employing directed energy deposition as an additive manufacturing process. The manufacturing method is performed by placing the base member in a machining area of a machine tool configured to perform subtractive machining. Accordingly, a composite member can be obtained that is manufactured through additive manufacturing and that is in a state in which the composite member can be promptly machined.

Additive manufacturing techniques are used to achieve customized preforms for repair or manufacture of turbomachinery. A method of modifying a section of a product includes forming, a preform set to fit the section. A base material is selected with properties desired for the modification of the section. A binder is selected that vaporizes at a temperature below a melting point of the base material. The preform set is built by the selective application of the binder to the base material to achieve design dimensions of the section when the preform is joined to the section. The section is prepared for effecting the extent of modification and the preform is positioned on the section. The section and the preform are heated to substantially eliminate the binder from the preform and then thermally processed to harden the preform and to bond the preform to the section.

The present invention discloses a roll forming device for micro-casting and rolling additive manufacture for large special-shaped pipes, comprises a supporting assembly, a sliding assembly, and a roller system assembly. The sliding assembly includes a guide rail, hydraulic cylinders, hydraulic push rods and a guide rail sliding frame. Two ends of the guide rail are respectively fixedly connected with the centers of two ends of the frame plate in a width direction, the lower surface of the sliding plate of the guide raid sliding frame is slidably connected with the guide rail, housings of the hydraulic cylinders are respectively fixedly connected to the centers at both ends of the frame plate in the width direction. The invention adopts the structures of the guide rail, the hydraulic cylinder and the steering hinge rod to expand the working range of the device and the working types of workable parts.

An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part (the “AM part”) is disclosed. The apparatus may include a chamber, a support surface within the chamber, and one or more nozzles within the chamber. The nozzles may be the same size or different sizes. The support surface may be configured to support the AM part. The support surface may have one or more openings sized and configured to allow the fluid to pass through the opening(s). The nozzles may be configured to spray a fluid at the AM part, and the spray may be an atomized or semi-atomized spray of the fluid. For removing support material from parts with internal spaces, such as cavities or passages, the apparatus can include a nozzle at the end of an adjustable flexible hose member that can be adjusted to spray into an internal space of the part. Alternatively, for removing unwanted support material from multiple parts with internal spaces, the apparatus may include a submersion tank.
