Abstract: Systems and methods of support structures in powder-bed fusion (PBF) are provided. Support structures can be formed of bound powder, which can be, for example, compacted powder, compacted and sintered powder, powder with a binding agent applied, etc. Support structures can be formed of non-powder support material, such as a foam. Support structures can be formed to include inductive components that can be used to facilitate removal of the support structures in the presence of an external magnetic field. Additionally, support structures can be formed to break when a fluid, such as air or water, creates a force and/or pressure at a connection point interface.

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: An additively manufactured node is disclosed. A node is an additively manufactured (AM) structure that includes a feature, e.g., a socket, a channel, etc., for accepting another structure, e.g., a tube, a panel, etc. The node can include a node surface of a receptacle extending into the node. The receptacle can receive a structure, and a seal interface on the node surface can seat a seal member between the node surface and the structure to create an adhesive region between the node and the structure, the adhesive region being bounded by the node surface, the structure, and the seal member. The node can also include two channels connecting an exterior surface of the node to the adhesive region. In this way, adhesive can be injected into the adhesive region between the node and the structure, and the adhesive can be contained by the seal member.

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.
