A dual wall component includes a first outer wall extending from a leading edge to a trailing edge, a first inner wall spaced from the first outer wall by a plurality of first cavities and first ribs, a second inner wall spaced from the first inner wall by a plurality of second cavities and second ribs, and a second outer wall extending from the leading edge to the trailing edge and spaced from the second inner wall by a plurality of third cavities and third ribs. Portions of the first and second outer walls have thicknesses less than about 0.018" (0.457 mm). In a method for forming a dual wall component, component walls are formed by additive manufacturing and without using cores to form the cavities. |
