Abstract: An additively manufactured (AM) object (102) may include a body (104) including an opening in an exterior surface (110) thereof, the opening (106) having a shape and a first area at the exterior surface (110) of the body (104). A mask (100) may be positioned over the opening (106). The mask (100) has the shape of the opening (106) and a second area that is larger than the first area so as to overhang (112) the exterior surface (110) of the body (104) about the opening (106). A plurality of support ligaments (130) couple to the mask (100) and the exterior surface (110) of the body (104) at a location adjacent to the opening (106) to support a portion of the mask (100). A coating (134) can be applied to the object, and the mask (100) removed. The final AM object includes a plurality of ligament elements (180) extending from the exterior surface (110) of the body (104) and through the coating (134) adjacent the opening (106), each ligament element (180) at least partially surrounded by the coating (134)..
