Abstract: Methods for manufacturing three-dimensional objects using an additive manufacturing technique, methods for forming dye-infused feed material for an additive manufacturing technique, and vehicles including additive manufactured components are provided. An exemplary method for manufacturing a three-dimensional object using an additive manufacturing technique includes solubilizing a dye into a medium in the form of a supercritical fluid and contacting a feed material with the medium to infuse the dye into the feed material to form dye-infused feed material. The method further includes locally melting the dye-infused feed material in selected regions of a layer corresponding to a cross-section of a three-dimensional object being formed and solidifying the dye-infused feed material into a solid layer of dye-infused material. Further, the method includes repeating the local melting and solidifying steps to form the three-dimensional object made up of a plurality of solid layers of dye-infused material.

Abstract: A fixture assembly for testing or measuring a portion of a battery electrode includes a top plate, a baseplate, a connector and a support member. The top plate includes holes for creating a low-pressure region along a top surface of the top plate to hold the portion of the battery electrode to the top plate. The baseplate includes a bottom plate and side walls. The side walls extend upward from the bottom plate and define a vacuum chamber with the top plate. The connector is attached to the baseplate and configured to be connected to a vacuum hose for drawing air from the vacuum chamber to pull the portion of the battery electrode to the top plate. The support member is attached to the baseplate and configured to hold the fixture assembly in place relative to a measuring device that measures a physical characteristic of the battery electrode.
