A first ring extends from the first surface and a second ring extends from the first surface radially outwardly of the first ring. The second ring is spaced from the first ring by a first gap. A second member includes a second base having a first surface portion. A first ring element extends from the first surface portion and a second ring element extends from the first surface portion radially inwardly of the first ring element. The second ring element is spaced from the first ring element by a second gap. The second ring is positioned in the second gap, and the second ring element is positioned in the first gap. The first member is rotatable relative to the second member.

    Abstract: A system and method for additive manufacturing are provided. The system includes a structure defining a chamber for manufacturing parts via additive manufacturing. A powder metal applicator is configured to deposit layers of powder metal material to build a part on a build platform. A laser source is configured to direct one or more laser beams onto each layer of powder metal material to fuse the powder metal material, wherein metal condensate is created by the laser beam(s) contacting the powder metal material. An element spaced apart from the layers of powder material has a temperature different than the chamber temperature, so that the element is configured to attract or repel the metal condensate by virtue of the temperature differential between the element and the chamber. The method includes using the element having the different temperature to attract or repel the metal condensate within the chamber.

    Abstract: A configurable build volume system for a powder bed fusion manufacturing process includes a chamber wall defining a chamber, the chamber wall extending in the X-, Y-, and Z-axis directions, a plurality of build platforms enclosed within the chamber, a plurality of adjustment mechanisms coupled to the plurality of build platforms such that each build platform is coupled to a separate adjustment mechanism, a sensor mounted within the chamber and configured to capture data regarding a Z-axis position of each of the plurality of build platforms, and a controller in electronic communication with the plurality of adjustment mechanisms and the sensor. The controller receives the Z-axis position data and generates a plurality of control signals to adjust a Z-axis position of each of the plurality of build platforms and each of the plurality of build platforms is actively and independently controlled by the controller.

    Abstract: Systems and methods are provided for locating a pair of components relative to one another using complex surfaces. One component has a complex surface, where the complex surface is smoothly contoured. Another component is shaped to be connected with the first component. A fixture locates the first component relative to the second component. The fixture includes a locator with a complex surface region shaped to mate with the complex surface of the one component to locate the fixture relative to that component. The fixture includes another locator to locate the fixture relative to the second component.

    Abstract: An assembly for a vehicle includes a first member including a plurality of elastically deformable locating protrusions extending outward, and a second member defining a cavity extending inward and including a plurality of elastically deformable compression features disposed within the cavity. The locating protrusions of the first member are disposed within the cavity of the second member in press fit engagement with the compression features of the second member to secure the first member relative to the second member. The average of the elastic deformation between all of the locating protrusions of the first member and all of the compression features of the second member precisely aligns the first member relative to the second member. The assembly may include but is not limited to a multiple unit battery pack, a multiple unit fuel cell pack, a dashboard assembly or adjoining body panels.
