An example system for fabricating an infiltrated downhole tool includes a mold assembly having one or more component parts and defining an infiltration chamber to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated downhole tool. One or more thermal conduits are positioned within the one or more component parts for circulating a thermal fluid through at least one of the one or more component parts and thereby placing the thermal fluid in thermal communication with the infiltration chamber.

1. A system for fabricating an infiltrated downhole tool, comprising: a mold assembly having one or more component parts and defining an infiltration chamber to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated downhole tool; andone or more thermal conduits positioned within the one or more component parts for circulating a thermal fluid through at least one of the one or more component parts and thereby placing the thermal fluid in thermal communication with the infiltration chamber;wherein the mold assembly includes a metal mandrel positioned within the infiltration chamber, the system further comprising insulation materials interposing the one or more thermal conduits and the metal mandrel. 2. The system of claim 1, wherein the infiltrated downhole tool is selected from the group consisting of a drill bit, a cutting tool, a non-retrievable drilling component, a drill bit body associated with casing drilling of wellbores, a drill-string stabilizer, a cone for a roller-cone drill bit, a model for forging dies used to fabricate support arms for roller-cone drill bits, an arm for a fixed reamer, an arm for an expandable reamer, an internal component associated with expandable reamers, a rotary steering tool, a logging-while-drilling tool, a measurement-while-drilling tool, a side-wall coring tool, a fishing spear, a washover tool, a rotor, a stator, a blade for a downhole turbine, and a housing for a downhole turbine. 3. The system of claim 1, wherein the thermal fluid is a fluid selected from the group consisting of a gas, water, steam, an oil, a coolant, a molten metal, a molten metal alloy, a fluidized bed, a molten salt, and any combination thereof. 4. The system of claim 1, wherein the one or more component parts are selected from the group consisting of a mold, a gauge ring, a funnel, a binder bowl, a cap, a displacement core, and one or more nozzle displacement legs. 5. The system of claim 1, further comprising at least one of: a heat exchanger fluidly coupled to the one or more thermal conduits for thermally conditioning the thermal fluid; anda pump fluidly coupled to the heat exchanger and the one or more thermal conduits to circulate the thermal fluid through the one or more component parts. 6. The system of claim 1, wherein the one or more thermal conduits form a spiral or helical array. 7. The system of claim 1, wherein the one or more thermal conduits comprise a plurality of thermal conduits, and wherein one or more of the plurality of thermal conduits are independently operable. 8. The system of claim 1, wherein the one or more component parts include a mold, a first nozzle displacement leg, and a second nozzle displacement leg, and wherein the one or more thermal conduits penetrate the mold at a first location, extend through the first nozzle displacement leg, extend through the second nozzle displacement leg, and penetrate the mold at a second location. 9. The system of claim 8, wherein the one or more component parts include a mold, one or more nozzle displacement legs, and a displacement core, and wherein the one or more thermal conduits penetrate the mold, extend through the first nozzle displacement leg, and extend through the displacement core to eject the thermal fluid into the infiltration chamber. 10. The system of claim 1, wherein the one or more component parts comprise a first component part and a second component part, the first component part defining a first fluid flow passage and a first mating interface, and the second component part defining a second fluid flow passage and a second mating interface. 11. The system of claim 10, wherein the first mating interface defines a protrusion and the second mating interface defines a recess that receives the protrusion. 12. A system for fabricating an infiltrated downhole tool, comprising: a mold assembly having one or more component parts and defining an infiltration chamber to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated downhole tool; andone or more thermal conduits positioned within the one or more component parts for circulating a thermal fluid through at least one of the one or more component parts and thereby placing the thermal fluid in thermal communication with the infiltration chamber;wherein the one or more component parts comprise a first component part and a second component part, the first component part defining a first fluid flow passage and a first mating interface, and the second component part defining a second fluid flow passage and a second mating interface;wherein the first and second mating interfaces are complimentarily angled to align the first and second fluid flow passages and thereby allow the thermal conduit to pass the first and second mating interfaces. 13. The system of claim 12, wherein the mold assembly includes a metal mandrel positioned within the infiltration chamber, the system further comprising insulation materials interposing the one or more thermal conduits and the metal mandrel. 14. The system of claim 12, wherein the one or more thermal conduits comprise a plurality of thermal conduits, and wherein one or more of the plurality of thermal conduits are independently operable. 15. The system of claim 12, wherein the one or more component parts include a mold, a first nozzle displacement leg, and a second nozzle displacement leg, and wherein the one or more thermal conduits penetrate the mold at a first location, extend through the first nozzle displacement leg, extend through the second nozzle displacement leg, and penetrate the mold at a second location. 16. A system for fabricating an infiltrated downhole tool, comprising: a mold assembly having one or more component parts and defining an infiltration chamber to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated downhole tool; andone or more thermal conduits positioned within the one or more component parts for circulating a thermal fluid through at least one of the one or more component parts and thereby placing the thermal fluid in thermal communication with the infiltration chamber;wherein the one or more component parts comprise a first component part and a second component part, the first component part defining a first fluid flow passage and a first mating interface, and the second component part defining a second fluid flow passage and a second mating interface;wherein at least one of the first and second mating interfaces defines a channel, and wherein the thermal fluid flows within the channel to locate one of the first and second fluid flow passages and thereby pass the first and second mating interfaces. 17. The system of claim 16, wherein the mold assembly includes a metal mandrel positioned within the infiltration chamber, the system further comprising insulation materials interposing the one or more thermal conduits and the metal mandrel. 18. The system of claim 16, wherein the one or more thermal conduits comprise a plurality of thermal conduits, and wherein one or more of the plurality of thermal conduits are independently operable. 19. The system of claim 16, wherein the one or more component parts include a mold, a first nozzle displacement leg, and a second nozzle displacement leg, and wherein the one or more thermal conduits penetrate the mold at a first location, extend through the first nozzle displacement leg, extend through the second nozzle displacement leg, and penetrate the mold at a second location.
