摘要： An approach for supporting a wax pattern (12) during investment casting. The approach described herein forms a support structure (30) to support the wax pattern (12) during investment casting. The support structure (30) has a capping structure (32) with a geometry that can match a profile of a lower region (18) of the wax pattern (12), and at least one support brace (38) extending outward from the support capping structure (32). The support structure (30) can be placed on a surface of the lower region (18). The support capping structure (32) can form a defined envelope (36) to enclose the lower region (18) of the wax pattern (12). The support structure (30) is connected to a base plate (22) by the support brace(s) (38). The capping structure (32) and the support brace(s) (38) secure the wax pattern (12) to the base plate (22) and distribute the load of the wax pattern (12) to maximize strength while minimizing the risk of a discontinuity in the wax or shell that could affect the casting process.
