  • Publication number: 20190146456
    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.

  • Publication number: 20190105852
    Abstract: Techniques for inlaying a composite material within a tooling shell are disclosed. In one aspect, an additively manufactured tooling shell is provided, into which a composite material is inlaid and cured. A surface of the tooling shell is provided with indentations or another mechanism to enable adherence between the composite material and the tooling shell. The resulting integrated structure is used as a component in a transport structure.

  • Publication number: 20190079492
    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.

  • Publication number: 20190076925
    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.

  • Publication number: 20190030751
    Abstract: Some embodiments of the present disclosure relate to an additively manufactured transport structure. The transport structure includes cavities into which components that use an external interface are inserted. A plurality of components are assembled and integrated into the vehicle. In an embodiment, the components and frame are modular, enabling reparability and replacement of single parts in the event of isolated failures.

  • Publication number: 20190030605
    Abstract: Some embodiments of the present disclosure relate to additively manufactured vehicle exterior structures, designed to enclose the vehicle surface and support required operational loads. The vehicle structure includes cavities into which components that require an external interface are inserted. A plurality of components are assembled and integrated into the vehicle structure. The structure may be 3-D printed using multiple printing techniques applied in parallel or in series. In an embodiment, the components and structure are modular, use multiple materials and manufacturing techniques, and enable reparability and replacement of single parts.

  • Publication number: 20190002143
    Abstract: An automated wrapping technique for vehicle components is disclosed. A component to be wrapped is secured to a fixture, which in turn is coupled to an actuator. A grabber arm grabs a length of wrap from a feed roll. The grabber arm removes the backing and spreads the wrap over the component. The actuator pushes the component upward until the wrap contacts the component surface. An applicator may concurrently smooth the wrap and evacuate trapped air. The wrap may be cut around the periphery of the component, and hemmed. A controller provides instructions to automate the wrapping mechanism.

  • Publication number: 20180250889
    Abstract: Techniques for 3-D printing parts using spray forming are disclosed. A 3-D printer receives instructions for printing a structure, where the instructions based on a data model of the structure. The 3-D printer receives a suitable material such as a metal, plastic, or composite, and prints the structure based on the instructions using spray forming. In one embodiment, the 3-D printer employs spray forming to finish an angled surface of a 3-D printed part having a stair-stepped effect.

  • Publication number: 20180229401
    Abstract: Techniques for 3-D printing a tooling shell for use in producing panels for a transport structure, such as an automobile, boat, aircraft, or other vehicle, or other mechanical structure, are disclosed. A 3-D printer may be used to produce a tooling shell containing Invar and/or some other material for use in molding the panels. A channel may be formed in a 3-D printed tooling shell for enabling resin infusion, vacuum generation or heat transfer. Alternatively, or in addition to, one or more hollow sections may be formed within the 3-D printed tooling shell for reducing a weight of the shell.
