Claim 17:
18. A method of fabricating a composite component, the composite component comprising a first material, a second material, and a third material, said method comprising:
depositing the first material and the third material onto a surface of an additive manufacturing system; and
operating an energy beam source of the additive manufacturing system to consolidate the first material and the third material using a first process to form:
a first section comprising the first material, said first section comprising a plurality of first section unit cells joined together;
a third section comprising the third material, said third section surrounding the first section; and

depositing a second material within the first section such that the second material surrounds each unit cell of 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 section surrounding each unit cell of the plurality of first section unit cells;
wherein the first material and the third material are harder than the second material, and the first material and the third material have a smaller grain size than the second material when the second material is deposited.
