Abstract

Calibration components having a turbomachine component form factor and methods of fabricating the calibration components using an additive manufacturing system are provided. A calibration component includes a main body and one or more representative quality indicators. The one or more representative quality indicators are disposed within the main body of the calibration component. The representative quality indicators include a cavity that has a material disposed within the cavity.

First claim

What is claimed is:

1 . A calibration component having a form factor of a turbomachine component, the calibration component comprising:
a main body; and one or more representative quality indicators disposed within the main body of the calibration component, the representative quality indicators comprising a cavity having a material disposed within the cavity.

2 . The calibration component as in claim 1 , wherein the cavity is spherical.

3 . The calibration component as in claim 1 , wherein the material disposed in the cavity is a powder material in powder form.

4 . The calibration component as in claim 3 , wherein the main body is formed from the powder material.

5 . The calibration component as in claim 1 , wherein the material is a first material, and wherein the main body of the calibration component is formed from a second material that is different than the first material.

6 . The calibration component as in claim 1 , further comprising a plurality of representative quality indicators.

7 . The calibration component as in claim 6 , wherein the plurality of representative quality indicators comprise differently sized representative quality indicators.

8 . The calibration component as in claim 6 , wherein the plurality of representative quality indicators are arranged in a pattern.

9 . The calibration component as in claim 6 , wherein the plurality of representative quality indicators are not arranged in a pattern.

10 . The calibration component as in claim 1 , wherein the one or more representative quality indicators each define a diameter of between about 0.01 inches and about 0.1 inches.

11 . The calibration component as in claim 1 , wherein a first density of the material within the cavity may be less than a second density of the main body.

12 . The calibration component as in claim 11 , wherein the first density is between about 10% and about 90% less than the second density of the main body.

13 . The calibration component as in claim 1 , wherein calibration component comprises an area of high manufacturing stress, and wherein the one or more representative quality indicators are disposed in the area of high manufacturing stress.

14 . The calibration component as in claim 1 , wherein the turbomachine component form factor is one of a compressor section component, a combustion section component, or a turbine section component.

15 . A method of fabricating a calibration component having a turbomachine component form factor using an additive manufacturing system, the method comprising:
irradiating a layer of powder in a powder bed to form a fused region, wherein the powder is disposed on a build plate; providing a subsequent layer of powder over the powder bed by passing a recoater arm over the powder bed; and repeating the irradiating and providing steps until the calibration component is formed on the build plate, the calibration component comprising:
a main body; and
one or more representative quality indicators disposed within the main body of the calibration component, the representative quality indicators comprising a cavity having the powder disposed within the cavity.

16 . The method as in claim 15 , wherein passing the recoater arm over the powder bed further comprises maintaining a level of powder in the powder bed.

17 . The method as in claim 16 , wherein the cavity is disposed below the level of powder during the fabrication of the calibration component.

18 . The method as in claim 17 , further comprising filling the cavity with powder during the fabrication of the calibration component each instance that the recoater arm passes.

19 . The method as in claim 15 , wherein the cavity is spherical.

20 . The method as in claim 15 , further comprising removing the calibration component from the build plate.
