Способ относится к машино- и приборостроению и может быть использован для получения трехмерных сложнофасонных изделий из порошковых материалов. Изобретение обеспечивает снижение энергетических затрат за счет спекания под действием лазерного излучения меньшей мощности. Способ включает смешивание исходного порошка с добавкой порошка, обладающей повышенной по сравнению с исходным способностью поглощения лазерного излучения, послойное нанесение порошка на подложку и его послойное избирательное спекание под действием лазерного излучения согласно системе плоскостей, секущих изделие в направлении, параллельном формирующим его слоям.The method relates to machine building and instrument making and can be used to obtain three-dimensional difficult-to-form articles from powder materials. The invention provides a reduction in energy costs due to sintering under the action of laser radiation of lower power. The method involves mixing the original powder with the addition of a powder that has an increased absorption of laser radiation compared to the initial one, layer-by-layer deposition of the powder on a substrate and its layer-by-layer selective sintering under the action of laser radiation according to a system of planes that cut the product in a direction parallel to the layers forming it.
