Abstract
A method of integrally forming at least one stiffener onto a sheet metal component configured to carry a load is provided including generating a stereolithography file. The stereolithography file includes a surface geometry of the at least one stiffener extending from a surface of the sheet-metal component. The surface geometry of the stereolithography file is sliced into a plurality of thin strips. The plurality of thin strips is substantially parallel to the surface of the sheet metal component. Energy from an energy source is applied to a powdered material such that the powdered material fuses to form the plurality of thin strips. One of the plurality of thin strips is integrally formed with the surface of the sheet-metal component. Each of the plurality of thin strips is integrally formed with an adjacent thin strip to create at least one stiffener.
