1. A method of making a rotary component, comprising:
forming a first structure using additive manufacturing;
forming a support structure extending from the first structure using additive manufacturing;
forming a second structure over the support structure using additive manufacturing; and
separating the support structure by rotating the first structure and the second structure about an axis, including:
configuring a central portion of the support structure to fracture in response to a first centrifugal force; and
configuring a first end of the support structure to separate from the first structure and a second end of the support structure to separate from the second structure in response to a second centrifugal force different from the first centrifugal force.
