The invention provides a multi-energy field additive manufacturing forming system. By combining SLM technology with FDM and other technologies to give full play to their respective advantages, it can theoretically realize high-precision forming of complex metal components of any size. In the multi-energy field additive manufacturing forming system, the Y-direction horizontal guide rail system can drive the FDM printing system, milling and cutting processing system, and laser printing optical path system to move up and down along the Z-direction lifting guide rail system; the partial powder bed protective cover is fixed and installed It is located below the laser printing optical path system, and is closed and isolated from the laser printing optical path system; the upper end surface of the partial powder bed protective cover has a light-passing area corresponding to the laser printing optical path system, and the lower end surface of the partial powder bed protective cover is empty. The width is greater than the distance between the first side wall and the second side wall; the left and right sides of the lower part of the partial powder bed protective cover are provided with channels for exhausting smoke; the powder spreading and powder feeding devices are arranged in front of the partial powder bed protective cover side.
Description
technical field [0001] The invention belongs to the technical field of additive manufacturing and relates to an additive manufacturing forming system, which is especially suitable for processing large-sized and complex components. Background technique [0002] Additive manufacturing (AM), also known as "3D printing", is based on digital CAD model data and adopts the manufacturing principle of superposition method similar to mathematical integration to reduce the manufacturing of three-dimensional solids to two-dimensional cross-sections. The point-by-layer manufacturing method realizes the dimension reduction forming of three-dimensional parts, which is not limited by the complexity of the shape, and can realize fast, high-quality, efficient, economical, fully intelligent and fully flexible manufacturing of parts with arbitrary complex shapes. Additive manufacturing is an important part of the advanced manufacturing industry. It is a high-end digital manufacturing technology...
