A method for fabricating a ceramic casting mold system, comprising: placing a ceramic filled resin comprising ceramic particles, a monomer and an photoinitiator within a reservoir of a stereolithography apparatus that includes the reservoir and an energy source; drawing a cross section of the ceramic casting mold system with the energy source on a layer of the ceramic filled resin to polymerize the monomer and form a substantially cured layer comprising a polymer binder holding the ceramic particles of the layer together, wherein the cross section is defined by a data file that defines a plurality of cross sections of the ceramic casting mold system representative of a gas turbine engine component; covering the substantially cured layer with another layer of the ceramic filled resin; after covering the substantially cured layer with another layer of the ceramic filled resin, drawing another cross section of the ceramic casting mold system with the energy source on the another layer of the ceramic filled resin to polymerize the monomer and form a substantially cured another layer comprising the polymer binder holding the ceramic particles of the another layer together, wherein the another cross section is defined by the data file that defines the plurality of cross sections of the ceramic casting mold system representative of the gas turbine engine component; repeating the covering and the drawing for each of the plurality of cross sections to fabricate the ceramic casting mold system with a plurality of substantially cured layers; heating the ceramic casting mold system to substantially remove the polymer binder; and sintering the ceramic casting mold system to a density greater than 70%. placing a ceramic filled resin comprising ceramic particles, a monomer and an photoinitiator within a reservoir of a stereolithography apparatus that includes the reservoir and an energy source; drawing a cross section of the ceramic casting mold system with the energy source on a layer of the ceramic filled resin to polymerize the monomer and form a substantially cured layer comprising a polymer binder holding the ceramic particles of the layer together, wherein the cross section is defined by a data file that defines a plurality of cross sections of the ceramic casting mold system representative of a gas turbine engine component; covering the substantially cured layer with another layer of the ceramic filled resin; after covering the substantially cured layer with another layer of the ceramic filled resin, drawing another cross section of the ceramic casting mold system with the energy source on the another layer of the ceramic filled resin to polymerize the monomer and form a substantially cured another layer comprising the polymer binder holding the ceramic particles of the another layer together, wherein the another cross section is defined by the data file that defines the plurality of cross sections of the ceramic casting mold system representative of the gas turbine engine component; repeating the covering and the drawing for each of the plurality of cross sections to fabricate the ceramic casting mold system with a plurality of substantially cured layers; heating the ceramic casting mold system to substantially remove the polymer binder; and sintering the ceramic casting mold system to a density greater than 70%.
