A method, comprising:
- building a integral ceramic casting mold shell by a free form fabrication technique, the casting mold shell has an internal cavity adapted to receive a molten metal;
- reinforcing the ceramic casting mold shell;
- positioning a metallic starter seed within the ceramic casting mold shell, the metallic starter seed is positioned to receive molten metal therein;
- filling the internal cavity with molten metal;
- and
- withdrawing heat through the metallic starter seed to directionally solidify the molten metal within the internal cavity.
