1. A method for manufacturing a metallic component, the method comprising:
forming the metallic component with a support structure using an additive manufacturing process, the support structure including support walls arranged to form flow passages with each passage including a cross-sectional area that is large enough to allow a fuel mixture to flow there through and a flame to propagate there through without choking the flow of the fuel mixture and without choking the flame propagation;
placing the metallic component with the support structure into a chamber and sealing the chamber;
introducing the fuel mixture into the chamber after sealing the chamber; and
igniting the fuel mixture in the chamber to remove one or more of the support walls of the support structure from the metallic component.
