An integrally-formed metal-casting mold loaded with a solid-metal ingot in an ingot-cup portion thereof is heated in a furnace under vacuum to a temperature sufficient to melt the solid-metal ingot. The ingot-cup portion is operatively coupled to a component-mold portion of the mold via a funnel portion thereof, either directly or through a riser portion operatively coupled to a base of the component-mold portion, which provides for feeding molten metal melted from the ingot to cast a part in the component-mold portion. Molten metal in excess of what is needed to cast the part flows either into the riser portion, or into a fluid conduit that extends above the component-mold portion. The molten metal may be fed to the component-mold portion through a molten-metal filter to reduce flow rate or remove contaminants. The mold may be formed either as an investment mold or directly by additive manufacturing.
