摘要： The present application relates to the technical field of 3D printing apparatus, and discloses an electron beam melting and cutting composite 3D printing apparatus which comprises a box and an electron beam gun; wherein the box has a cavity formed therein; the cavity is provided therein with a cutting structure, a first Y-direction guide rail and a Y-direction movable platform; the electron beam gun has an emitting head formed in the cavity; the Y-direction movable platform is provided thereon with a Z-direction movable platform; the Z-direction movable platform is provided thereon with a powder spreading structure; the cutting structure has a cutting head configured for cutting a structural component formed by melting the metal powder; a shielding case is arranged between the emitting head and the Z-direction movable platform; the emitting head of the electron beam gun is inserted in an upper opening of the shielding case, and a lower opening of the shielding case is aligned with the Z-direction movable platform. When the electron beam gun emits an electron beam to perform melting machining, the generated heat of the high temperature is confined in the shielding case, which reduces the heat effect on other elements inside the cavity. Moreover, when using the cutting head to perform cutting machining, it can ensure that the temperature in the cutting area is constant, and thus the stress deformation of the structural component caused by a temperature variation during the forming process is reduced.
