ABSTRACT:
In a method and apparatus for forming a three-dimensional object, successive layers of metal are welded together to build the object. After each layer is formed a complementary material is placed adjacent the layer. In this manner, layers of material form a block of welded metal and complementary material. Then, all or a portion of the complementary material which serves as a support structure during forming can be removed. The welded layers are milled to a final shape either after each layer is formed or after all layers have been made. Existing CNG machines can be easily modified to practice the method.
