Abstract

A protective mask for a part, the part including a plurality of openings in a surface thereof, is provided. The protective mask includes a mounting member at least partially within each of at least two of the plurality of openings. Each mounting member includes a water soluble material. A masking member couples the at least two mounting members. The masking member includes a non-water soluble material. Each mounting member includes a first plurality of integral layers of the water soluble material, and the masking member includes a second plurality of integral layers of the non-water soluble material. The protective mask can be made by a two material additive manufacturing system. A related method is also provided.

First claim

What is claimed is:

1. A protective mask for a part, the part including a plurality of openings in a surface thereof, the protective mask comprising:
a mounting member at least partially within each of at least two of the plurality of openings, wherein each mounting member includes a water soluble material; and
a masking member coupled to the mounting member, the masking member including:
a non-water soluble material,
a first member coupled to each of the at least two mounting members, and
a second member coupling the first members together and physically separated from the part.

2. The protective mask of claim 1 , wherein the plurality of openings is positioned across the surface in a spaced manner, and wherein each opening includes a mounting member at least partially therein.

3. The protective mask of claim 1 , wherein the mounting member extends outwardly from a respective opening along the surface of the part.

4. The protective mask of claim 1 , wherein the mounting members and the masking member are formed using an at least two material additive manufacturing system.

5. The protective mask of claim 1 , wherein the plurality of openings is positioned in a pedestal in the surface of the part extending from another surface of the part.

6. The protective mask of claim 1 , wherein the masking member covers at least a portion of each mounting member.

7. The protective mask of claim 1 , wherein the protective mask includes an additively manufactured (AM) structure.

8. The protective mask of claim 7 , wherein the masking member covers at least a portion of each mounting member.

9. The protective mask of claim 7 , wherein the plurality of openings is positioned across the surface in a spaced manner, and wherein each opening includes a mounting member at least partially therein.

10. The protective mask of claim 7 , wherein the mounting member extends outwardly from a respective opening along the surface of the part.

11. The protective mask of claim 1 , wherein the second member is curved.

12. The protective mask of claim 1 , wherein exposing the at least two mounting members to water removes the at least two mounting members, and releases the masking member.

13. The protective mask of claim 1 , wherein the at least two mounting members each include a sawtooth pattern configured to mate with a sawtooth pattern in respective first members of the plurality of first members.

14. A protective mask for a part, the part including a plurality of openings in a surface thereof, the protective mask comprising:
a first mounting member at least partially within a first opening of the plurality of openings,
a second mounting member at least partially within a second opening of the plurality of openings,
wherein each of the first and second mounting members includes a water soluble material; and
a masking member coupled to the first and second mounting members, the masking member including:
a first masking member coupled to the first mounting member,
a second masking member coupled to the second mounting member, and
a connecting member coupling the first and second masking members together and physically separated from the part,
wherein the masking member includes a non-water soluble material.

15. The protective mask of claim 14 , wherein the plurality of openings is positioned across the surface in a spaced manner, and wherein each opening of the plurality of openings includes a respective mounting member of the first and second mounting members at least partially therein.

16. The protective mask of claim 14 , wherein each of the first and second mounting members extends outwardly from a respective opening of the plurality of openings along the surface of the part.

17. The protective mask of claim 14 , wherein the first and second mounting members and the first and second masking members are formed using an at least two material additive manufacturing system.

18. The protective mask of claim 14 , wherein the plurality of openings is positioned in a pedestal in the surface of the part extending from another surface of the part.

19. The protective mask of claim 14 , wherein exposing each mounting member of the first and second mounting members to water removes the first and second mounting members, and releases the masking member.

20. The protective mask of claim 14 , wherein each mounting member of the first and second mounting members includes a sawtooth pattern configured to mate with a complementary sawtooth pattern in a respective masking member of the first and second masking members.
