Abstract

A product building system uses a stage movable in X-Y-Z directions for holding and moving a product. A fixed laser is focused on a spot on the products. Strips of materials are fed tangent to a forming direction from two sources on a rotating platform. The laser continuously or periodically welds and fuses a strip on the product. Relative motion bends the strip to the desired product shape. The laser cuts a strip and welds a new strip to form alternating layers. Side by side strips are butt-welded. Cores are formed differently from outer surfaces,using the continuous feeding, welding, fusing, bending, welding and fusing process. A mill on the rotating platform brings a mill end tool into contact with the layers to smooth lateral and upper surfaces.
