Claim 12:
13. A method of fabricating a composite component, the method comprising:
forming a powder bed of a powdered material on a surface of an additive manufacturing system;
consolidating the powdered material using a first process facilitated by the additive manufacturing system to form a first section of the composite component and a third section of the composite component, wherein the first section comprising a plurality of first section unit cells joined together and the third section surrounds the first section;
depositing a second material within the first section such that the second material surrounds the plurality of first section unit cells; and
consolidating the second material using a second consolidation process different from the first process to form a second, solid section within the third section and within and surrounding each unit cell of the plurality of first section unit cells;
wherein the third section includes a third material, the powdered material and the third material are harder than the second material, and the powdered material and the third material have a smaller grain size than the second material when the second material is deposited.
