Turbine component and methods of making and cooling a turbine component

A method of making a turbine component comprising:

• forming an airfoil having a leading edge, a trailing edge portion extending to a trailing edge, and a plurality of axial cooling channels in the trailing edge portion, the plurality of axial cooling channels being arranged to permit axial flow of a cooling fluid from an interior of the turbine component at the trailing edge portion to an exterior of the turbine component at the trailing edge portion, thereby fluidly connecting the interior of the turbine component at the trailing edge portion with the exterior of the turbine component at the trailing edge portion;
• wherein the airfoil comprises a first section and a second section;
• and
• wherein the forming comprises metal three-dimensionally printing the first section, the second section, and the plurality of axial cooling channels, at least a portion of the plurality of axial cooling channels being formed at a formed surface of the first section or the second section.

A method of cooling a turbine component comprising:

• supplying a cooling fluid to an interior of the turbine component, the turbine component comprising:
• a root;
• and
• an airfoil extending from the root to a tip opposite the root, the airfoil forming a leading edge and a trailing edge portion extending to a trailing edge, the trailing edge portion having a plurality of axial cooling channels arranged to permit axial flow of the cooling fluid from an interior of the turbine component at the trailing edge portion to an exterior of the turbine component at the trailing edge portion;
• and
• directing the cooling fluid through the plurality of axial cooling channels through the trailing edge portion of the airfoil, each of the plurality of axial cooling channels fluidly connecting the interior of the turbine component at the trailing edge portion with the exterior of the turbine component at the trailing edge portion;
• wherein the airfoil comprises a first section and a second section;
• and
• wherein the first section, the second section, and the plurality of axial cooling channels are formed by metal three-dimensional printing and at least a portion of the plurality of axial cooling channels are formed at a formed surface of the first section or the second section.
