AI Technical Summary
Technical Problem
In the protection of surface openings of additive manufacturing parts, existing methods have long manufacturing time, high complexity and risk of coating rupture, especially after shot peening and coating treatment, it is difficult to effectively protect the openings.
Method used
The cantilever mask structure is employed, including attachment straps, cover members and separation members, coupled to the openings on the surface of the part by cantilever, providing spacing to prevent hammering material and coating from entering while facilitating mask removal.
Benefits of technology
Effectively protect the openings on the surface of the part, avoid coating breakage, simplify the manufacturing process, reduce complexity, and improve production efficiency.

Abstract
A mask (100) for additively manufacturing a part (102) includes a plurality of spaced-apart openings (106, 204) in a surface (110) of the part (102). The mask (100) is manufactured together with the part (102) and includes an attachment strap (120, 220) configured to be integrally coupled to the part (102) in a cantilevered manner between the openings (106, 204). First and second cover members (130, 140) include proximal ends (132, 142, 232) integrally coupled to the attachment strap (120, 220) and distal ends (134, 144, 234) extending at least partially above respective portions of the plurality of openings (106, 204). A separating member (152, 252, 352) extends from each of the first cover member and the second cover member (130, 140). The attachment ties (120, 220) are the only connection to the part (102). The cross-section of the mask (100) may have an umbrella shape.
