Abstract: A high precision Interface Node is disclosed. The Interface Node includes an integrated structure including one or more complex or sophisticated features and functions. The Interface Node may connect with another component or a Linking Node. The Interface Node is manufactured to achieve high precision functionality while enabling volume production. Current additive manufacturing technologies allow for the printing of high precision features to be manufactured, but generally this is performed at a slower rate. Consequently, in one aspect, the size of the Interface Nodes is reduced in order to overcome at least part of the slower production volume caused by creating the high precision Interface Nodes. The components and Linking Nodes to which the Interface Node is connected may only have basic features and functions. Accordingly, this latter category of components may use a high print rate and thus high production volume. In other embodiments, these low precision components may also be produced using a non-print manufacturing technology, such as casting, forging, etc., that may provide the requisite high throughput, or to high precision machined parts that lack the geometric flexibility of the Interface Node. In an embodiment, the Interface Nodes may be connected to other components via a Linking Node.

Abstract: Systems and methods for co-casting of additively manufactured, high precision Interface Nodes are disclosed. The Interface Node includes an integrated structure including one or more complex or sophisticated features and functions. Co-casting of Interface Nodes by casting a part onto the Interface Node results in a hybrid structure comprising the cast part and the additively manufactured Interface Node. The interface node may include at least one of a node-to-tube connection, node-to-panel connection, or a node-to-extrusion connection. In an embodiment, engineered surfaces may be provided on the Interface Node to improve the blend between the Interface Node and the cast part during the co-casting process.

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: Part retention features are disclosed for securing additively manufactured (AM) parts or for securing an AM part with another component, such as a node, panel, tube, extrusion, and the like, while an adhesive is being applied and/or while the adhesive is undergoing expansion due to a subsequent curing process. The retention features described herein can be used in the context of one or more AM parts such that the elements used to house the retention features (e.g., grooves, apertures, elastic elements, etc.) can advantageously be co-printed with the AM part, thereby removing a manufacturing step. The retention features also can be made with flatter profiles than existing solutions, making the overall structure smaller and less cumbersome to assemble.

Abstract: Techniques for joining nodes and subcomponents are presented herein. An additively manufactured first node or subcomponent has a groove. An additively manufactured second node or subcomponent has a tongue configured to extend into and mate with the groove to form a tongue-and-groove connection between the first and second node or subcomponent. In some aspects, the tongue-groove connection may extend substantially around a periphery of the node or subcomponent. In other aspects, a first subcomponent having a fluid pipe interface may be coupled via a tongue-groove connection to a second subcomponent having a fluid pipe interface, thereby enabling fluid to flow between subcomponents of the resulting integrated component.

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: A self-supporting lattice structure is provided with high strength-to-weight ratios. In an aspect, an additively manufactured structure is provided that includes a self-supporting lattice structure formed by a plurality of unit cells. Moreover, each unit cell includes a symmetrical frame with voids or cutouts extending through each of the side surfaces of the symmetrical frame to define a negative space therein. The negative space substantially reduces the density and overall weight of the self-supporting lattice structure.
