A method of manufacturing a net shaped seal comprises depositing a first layer of fine powder comprising an abradable feed stock material on a substrate. The method includes guiding a heat source over the fine powder material layer; fusing together the fine powder material; depositing a second layer of fine powder material over the first layer; fusing the second layer of fine powder material with a second pass of the heat source at predetermined locations; and repeating the depositing step and fusing step to form subsequent layers to form an abradable seal on the substrate. |
