Abstract

Aspects of the disclosure are directed to treating a substrate, the substrate including at least one of a refractory metal or a ceramic material, and depositing a media onto the treated substrate to generate a casting core. Embodiments include a fixture, a substrate located on the fixture, the substrate including at least one of a refractory metal or a ceramic material, and a delivery head that deposits media onto the substrate to generate a casting core. Aspects are directed to a core configured for casting a component, the core comprising: a substrate that includes at least one of a refractory metal or a ceramic material, and media deposited on the substrate, the media having a dimension within a range of between 0.5 and 100 micrometers.

Claims (19)

1. An apparatus configured for casting a component, the apparatus comprising:

a substrate comprising a ceramic material; and

media deposited on a portion of a surface of the substrate, the surface formed by the ceramic material, the media having a dimension within a range of between 0.5 and 500 micrometers, and the media forming a conductive trace on the surface of the substrate;

wherein the media comprises material that is removable while on the surface of the substrate by heat.

2. The apparatus of claim 1 , further comprising a casting core comprising the substrate and the media.

3. The apparatus of claim 2 , further comprising:

a shell;

the casting core configured to be disposed within the shell.

4. The apparatus of claim 3 , further comprising metal superalloy arranged in a cavity within the shell and adjacent the casting core.

5. The apparatus of claim 2 , wherein the casting core is configured for casting a component for an engine.

6. The apparatus of claim 5 , wherein the component comprises a blade, a vane, a turbine shroud, an end wall, an exhaust nozzle or a liner.

7. The apparatus of claim 5 , wherein the casting core is configured for casting a turbine blade where the casting core forms at least a passage within the turbine blade.

8. The apparatus of claim 1 , wherein the media includes at least one of a ceramic, a metal, a metal alloy, an intermetallic compound, carbon, glass, or a polymer.

9. The apparatus of claim 1 , wherein the media is a printed media.

10. The apparatus of claim 1 , wherein the media comprises material with a microstructure that is modifiable by selective dissolution or chemical etching.

11. An apparatus configured for casting a component, the apparatus comprising:

a substrate comprising a ceramic material; and

media deposited on a portion of a surface of the substrate, the surface formed by the ceramic material, the media having a dimension within a range of between 0.5 and 500 micrometers, and the media forming a conductive trace on the surface of the substrate;

wherein the media comprises polymer.
