Systems, devices, and methods for use with aerospace parts

1. A method, comprising:

creating a drawing of a stencil having an opening;

manufacturing the stencil based on the drawing such that the stencil defines the opening therethrough, wherein the stencil is manufactured via 3D printing;

positioning the stencil onto an aerospace part, such that the aerospace part is accessible through the opening, wherein the stencil is custom to the aerospace part;

positioning a masking medium onto the aerospace part through the opening;

removing the stencil from the aerospace part, such that the masking medium remains on the aerospace part; and

treating the aerospace part with the masking medium thereon.

2. The method of claim 1 , wherein the stencil is shaped as a tray.

3. The method of claim 1 , wherein the stencil includes a wall extending about the opening.

4. The method of claim 1 , wherein the aerospace part includes a cell having a wall, wherein the stencil includes a portion having a U structure for mounting onto the wall.

5. The method of claim 1 , wherein the stencil is shaped as a corner.

6. The method of claim 5 , wherein the stencil includes a plurality of walls, wherein at least one of the walls defines the opening.

7. The method of claim 5 , wherein the stencil includes a floor defining the opening.

8. The method of claim 1 , wherein the stencil is tubular.

9. The method of claim 8 , wherein the stencil is threaded.

10. The method of claim 8 , wherein the stencil includes a pair of portions that engage with each other.

11. The method of claim 10 , wherein the pair of portions mate with each other.

12. The method of claim 1 , wherein the stencil includes a first portion and a second portion, wherein the first portion is hingedly coupled to the second portion.

13. The method of claim 12 , wherein the first portion is hingedly coupled to the second portion, such that the aerospace part fits between the first portion and the second portion as the first portion faces the second portion.

14. The method of claim 1 , wherein the masking medium is positioned onto the aerospace part through the opening based on a computational detection of the opening.

15. The method of claim 14 , wherein the computational detection involves at least one of a camera, a microphone, an ultrasonic sensor, a laser, a light detection and ranging, a radar, a proximity sensor, an spectrometer, an infrared sensor, a distance sensor, or a heat sensor.

16. The method of claim 1 , wherein creating the drawing, manufacturing the stencil, positioning the stencil, positioning the masking medium, removing the stencil, and treating the aerospace part occurs within a defined area.

17. A method, comprising:

creating a drawing of a stencil having an opening;

manufacturing the stencil based on the drawing, such that the stencil defines the opening therethrough, wherein the stencil is manufactured via 3D printing;

positioning the stencil onto a part, such that the part is accessible through the opening, wherein the stencil is custom to the part;

positioning a masking medium onto the part through the opening;

removing the stencil from the part, such that the masking medium remains on the part; and

treating the part with the masking medium thereon.

18. The method of claim 17 , wherein the part is an aerospace part positioned within a building.

19. The method of claim 17 , wherein the stencil is shaped as a tray.

20. The method of claim 17 , wherein the stencil includes a wall extending about the opening.

21. The method of claim 17 , wherein the part includes a cell having a wall, wherein the stencil includes a portion having a U structure for mounting onto the wall.

22. The method of claim 17 , wherein the stencil is shaped as a corner.

23. The method of claim 17 , wherein the stencil is tubular.

24. The method of claim 17 , wherein the stencil includes a first portion and a second portion, wherein the first portion is hingedly coupled to the second portion.

25. The method of claim 17 , wherein creating the drawing, manufacturing the stencil, positioning the stencil, positioning the masking medium, removing the stencil, and treating the part occurs within a defined area.
