Apparatus and methods for pressure casting using an indirect feed

A method, comprising:

• providing an apparatus comprising a manifold comprising one or more feed holes in direct communication with one or more channels, and the manifold removably coupled to one or more molds comprising a cavity, a first open end and a second open end joined by a surface, wherein a bottom portion of the surface is configured to rest on top of the one or more feed holes, and wherein a porous membrane is removably attached to the first open end of the mold;
• providing a ceramic slurry, wherein the cavity is indirectly filled with the ceramic slurry after the feed hole directly delivers ceramic slurry to an exterior bottom portion of the surface;
• indirectly filling the cavity;
• directly filling channels with the ceramic slurry;
• applying a pressure to the ceramic slurry to remove a liquid component of the ceramic slurry via the porous membrane and consolidate ceramic particles to form a cast body within the cavity of the removably coupled mold;
• and
• ejecting the removably coupled mold comprising the cast body.
