METHOD FOR PRODUCING THREE-DIMENSIONAL OBJECTS FROM POWDERS AND DEVICE FOR IMPLEMENTING SAME

The invention relates to the field of high-energy material processing and can be used in producing three-dimensional objects, having a gradient of properties, from powders. A method involves the selection of powders of various materials according to diameter, the successive application of layers of powder of a given thickness during the vertical displacement of a piston of a working bin with an object to be sintered, and the programmed selective sintering/melting of a given area in the plane of each layer. After sintering, unsintered powder is removed from a layer. The piston is then returned, and a layer of powder having a different diameter and being of a different material is applied and selectively sintered. The process is repeated the requisite number of times depending on the number of materials applied in a layer, producing sintered areas from powders of different materials in a single layer. When the object-sintering process is finished, the unsintered powder is removed from the working bin, and the powders are separated according to diameter, thus separating the powders of different materials. The separated powders are returned to feed bins and are re-used. The technical result consists in the possibility of producing objects having prescribed properties using powders of different materials located in a single horizontal plane in a single layer.
