Abstract
A method of forming tooling for fabricating a part made from a metal powder is described herein. The method includes forming a first sheet and second sheet. The first sheet includes a first protrusion defining a first cavity and a first flange extending about the first protrusion. The second sheet includes a second flange. Additionally, the method includes arranging the first sheet and the second sheet to abut together the first flange of the first sheet and the second flange of the second sheet and to define an enclosure. The enclosure includes a void defined between the first cavity of the first sheet and the second sheet. The void has a shape of the part. The method further includes welding together the first flange of the first sheet and the second flange of the second sheet along a portion of the first flange spaced away from the first protrusion.
