Claim 13:
14. A method of fabricating a turbomachine component using an additive manufacturing system, the method comprising:
irradiating a layer of powder in a powder bed to form a fused region, wherein the powder is disposed on a build plate;
providing a subsequent layer of powder over the powder bed by passing a recoater arm over the powder bed from a first side of the powder bed; and
repeating the irradiating and providing steps until the turbomachine component is formed on the build plate, the turbomachine component comprising:
an exterior portion, the exterior portion including a first end wall, a second end wall, and an outer band extending axially between the first end wall and the second end wall; and
an interior portion disposed within the exterior portion, the interior portion including a self-breaking inner band extending axially between the first end wall and the second end wall, the self-breaking inner band including a plurality of teeth disposed between the first end wall and the second end wall.
