A three-dimensional printing process, a swirling device, and a thermal management process are disclosed. The three-dimensional printing process includes distributing a material to a selected region, selectively laser melting the material, and forming a swirling device from the material. The swirling device is printed by selective laser melting. The thermal management process includes providing an article having a swirling device printed by selective laser melting, and cooling a portion of the article by transporting air through the swirling device.

1. A process for forming a thermally managed turbine component, comprising: forming a turbine component, the component being selected from the group consisting of a turbine shroud, a turbine bucket, and a turbine nozzle; andforming a plurality of vortex tubes in a substantially parallel arrangement
1. A process for forming a thermally managed turbine component, comprising: forming a turbine component, the component being selected from the group consisting of a turbine shroud, a turbine bucket, and a turbine nozzle; andforming a plurality of vortex tubes in a substantially parallel arrangement in the turbine component by a three-dimensional printing process, the three dimensional printing process including distributing a material to a selected region and selectively laser melting the material,wherein the plurality of vortex tubes are arranged and disposed to tangentially accept a pressurized fluid into chambers of the plurality of vortex tubes having circular or substantially circular profiles, and divide the pressurized fluid into first fluid streams and second fluid streams, the first fluid streams having elevated temperatures relative to the second fluid streams. 2. The process of claim 1, wherein forming the plurality of vortex tubes includes forming a plurality of Ranque-Hilsch vortex tubes. 3. The process of claim 1, further comprising forming at least one cooling channel in fluid communication with the plurality of vortex tubes, the cooling channel being arranged and disposed to accept the second fluid streams. 4. The process of claim 1, further comprising forming the plurality of vortex tubes in a turbine shroud as the turbine component. 5. The process of claim 1, further comprising forming the plurality of vortex tubes in a turbine bucket as the turbine component. 6. The process of claim 1, further comprising forming the plurality of vortex tubes in a turbine nozzle as the turbine component. 7. The process of claim 1, further comprising arranging and disposing the plurality of vortex tubes to be in fluid communication with respect to the first fluid streams with at least one of a hot gas path of a turbine, a portion of the turbine component to be purged, and a portion of the turbine component having a lower heat load. 8. The process of claim 1, wherein the selectively laser melting is in an inert gas atmosphere. 9. The process of claim 1, wherein the selectively laser melting is repeatedly performed to form the plurality of vortex tubes. 10. The process of claim 1, wherein the plurality of vortex tubes are formed from two-dimensional slices having a thickness between about 20 micrometers and about 100 micrometers. 11. The process of claim 1, wherein the plurality of vortex tubes are produced near-net-shape. 12. The process of claim 1, further including forming a turbulator in the chamber of at least one of the plurality of vortex tubes. 13. The process of claim 1, wherein the material is an atomized powder. 14. The process of claim 13, wherein the selectively laser melting is selected from the group consisting of electron beam melting, laser melting, and combinations thereof. 15. The process of claim 1, wherein the selected region is a substrate plate and the distributing of the materials is performed by using a coating mechanism. 16. The process of claim 15, wherein the material is selected from the group of materials consisting of thermoplastics, metals, metallics, ceramics, and combinations thereof. 17. The process of claim 15, wherein the material is selected from the group of materials consisting of stainless steel, tool steel, cobalt chrome, nickel, titanium, aluminum, nickel-based superalloys, cobalt-based superalloys, and combinations thereof.
