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.

Electrode testing fixture and system for material characterization and standardization

Systems and methods are provided for building a product by additive manufacturing and creating hollow volumes without including build supports in the hollow volume for the layers above the hollow volume. An additive manufacturing cell includes a material handling device, a printer a material delivery system and an energy source to feed the sheets, print on the sheets, apply a powder on the printed sheets, build a hollow volume into the sheets and consolidate the sheets into a product with a contiguous structure.

Sheet lamination additive manufacturing for hollow sealed geometries without internal support

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.

Additive manufacturing with dye-infused feed material

Low waste methods for three-dimensional printing techniques are provided. A method includes performing a preceding additive infusion process including: solubilizing an additive into a medium in a supercritical fluid state; contacting a preceding material with the medium to infuse a portion of the additive into the preceding material to form a preceding additive-infused material; and separating remaining additive from the medium. Further, the method includes performing at least one succeeding additive infusion process including: solubilizing the remaining additive and, optionally, additional additive, into the medium in a supercritical fluid state; and contacting a succeeding material with the medium to infuse at least a portion of the remaining and additional additive into the succeeding material to form a succeeding additive-infused material, wherein the medium from the preceding additive infusion process is reused in the at least one succeeding additive infusion process.

Three-dimensional printing with reduced waste

Methods for forming a function-infused feed material for a three-dimensional printing technique, methods for manufacturing an additive-infused three-dimensional printed object, and vehicles including additive manufactured components are provided. An exemplary method for forming a function-infused feed material for a three-dimensional printing technique includes solubilizing a functional additive into a medium. Further, the method includes contacting a three-dimensional printing feed material with the medium to infuse the functional additive into the three-dimensional printing feed material to form the function-infused feed material.
