Abstract: 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.

Abstract: Apparatus and methods for additively manufacturing lattice structures are disclosed herein. Lattice structures are analyzed and automatedly generated with respect to surface proximity. A lattice structure is varied by changing lattice element variables including lattice density. An automated approach using CAD algorithms or programs can generate data for lattice structures based on design variables including volume, surface, angle, and position.
