    摘要： A method is provided for casting a component (170). Accordingly, data indicative of at least one location of a unitary core-shell mold (300) which is susceptible to a stress concentration is received. An additive manufacturing process is employed to form the unitary core-shell mold (300) defining a casting cavity (302). The unitary core-shell mold (300) includes a shell wall (304) defining an outer component (170) shape and a core wall (306) positioned inward of the shell wall (304). The core wall (306) defines an inner component shape. The core wall (306) and/or the shell wall (304) defines at least one reinforcement recess (308) adjacent to the at least one location which is susceptible to the stress concentration. Following the forming of the unitary core-shell mold (300), at least one support member (310) is positioned within the reinforcement recess (308) in contact with the at least one location. With the support member (310) in place, the component (170) is cast within the casting cavity (302).
