    摘要： The present application relates to the technical field of 3D printing apparatus, and discloses an electron beam melting and laser milling composite 3D printing apparatus, which comprises a base; wherein the base is provided thereon with a machining platform movable in a vertical direction; the base is further provided thereon with a powder spreading structure; an electron beam emitting structure and a laser milling head are arranged above the machining platform; the electron beam emitting structure is configured for emitting an electron beam to melt the metal powder layer and thereby form a single-layer or multi-layer approximate body; and the laser milling head is configured for emitting a laser beam to mill the single-layer or multi-layer approximate body. The 3D printing apparatus combine the removal machining taking laser milling as the main method with the incremental laminating manufacturing process taking electron beam melting 3D printing as the main method; therefore, the defects of the 3D printing technology in aspects such assizes, shape accuracies, or the like are overcome, the restrictions of cutting to the complexity of components or the like are overcome, the machined components do not need to be machined secondarily, and the problems of difficult clamping, large machining error, deformation of components occurring during machining, and difficult machining are avoided.

    摘要： Provided is a method and system for producing a slim-shaped sintered NdFeB magnet having a high level of coercive force and high degree of orientation, as well as a sintered NdFeB magnet produced by the aforementioned method or system. A system for producing a slim-shaped sintered NdFeB magnet according to the present invention includes: a filling unit 1 for supplying and filling alloy powder with a predetermined content of Dy into a mold 10 at a density within a range from 3.0 to 4.2 g/cm 3 ; an orienting unit 3 for subjecting the molds 10 holding the alloy powder 11 to an orienting process in a magnetic field; a sintering furnace (not shown) for sintering the alloy powder 11 together with the molds 10 holding the alloy powder 11 after the powder is oriented by the orienting unit 3; and a conveying unit, consisting of a belt conveyer and a manipulator (not shown), for conveying the molds 10 to any of the aforementioned units or the sintering furnace. The orienting unit 3 is provided with a heating and orienting coil 20 for heating the alloy powder 11 in the molds 10 before and/or after the application of the magnetic field so as to decrease the coercive force of the individual particles of the alloy powder 11.
