Molding tool with conformal portions and method of making the same

A method of making a molding tool, comprising:

• (a) depositing a thin layer of particulate;
• (b) selectively applying a binding agent to the thin layer of particulate to define a cross-section of a mold core package;
• repeating steps (a) and (b) to produce a mold core package having a sacrificial displacement body proximate a mold core package wall defining a mold surface;
• and
• applying a molten material to the mold core package to form a molding tool.

• repeating steps (a) and (b) to produce a mold core package having a sacrificial displacement body and a sacrificial displacement line;
• and
• applying a molten material to the mold core package such that the sacrificial displacement body and the sacrificial displacement line form voids in the mold core.
