Techniques for optimizing powder hole removal are disclosed. In one aspect, an apparatus for inserting powder removal features may identify what powder removal features are optimal for a given AM component, as well as the optimal location and physical characteristics of these features. The features are automatedly added to the component, and an FEA test is run. In the event of failure, the offending feature is removed and the process is repeated. If successful then the loose powder may be removed in a post-processing step following AM.

Apparatus and methods for optimization of powder removal features in additively manufactured components

Apparatus and methods for sealing powder holes in additively manufactured parts are presented herein. Powder holes are co-printed to facilitate post processing sealing. Embodiments include co-printed caps, friction welded caps, rivets, silicone plugs, co-printed tangs, multiple micro holes, layup, and spin forming. By using one or more of the above techniques, powder holes can be sealed on additively manufactured parts.
