Abstract: A shaped structure having a fixed ferromagnetic polymer material aligned to a unified alignment direction. The shaped structure may include ferromagnetic particles suspended in the fixed ferromagnetic polymer material, and the ferromagnetic particles are aligned to the unified alignment direction. A method of manufacturing a structure includes forming ferromagnetic polymer precursors, dispensing the ferromagnetic precursors into a shaped structure, applying a magnetic field to cause the ferromagnetic precursors to align to a unified crystallographic orientation, and finishing the shaped structure to form a ferromagnetic polymer with a fixed unified crystallographic orientation and produce the structure.

Abstract: An electrical core has a ferromagnetic material having discrete particles, the particles aligned in a unified crystallographic direction, a structural material holding the ferromagnetic material having the shape of a hollow rectangle, and a winding comprised of wires wound around the hollow rectangle to form a core. A method of producing an electrical core includes printing ferromagnetic particles in a shape of an electrical core, aligning the ferromagnetic particles to a unified crystallographic direction to produce aligned particles, depositing a structural material around the aligned particles to form a monolith with a center opening, and applying winding to finish the electrical core.

Abstract: An additive manufacturing device includes a stage configured to support a substrate. The device also includes a printhead disposed above the stage. The printhead is configured to heat a build material to a molten build material and to deposit the molten build material on the substrate in the form of droplets to fabricate an article. The device also includes a controlled heating and ablation system disposed proximal the printhead. The controlled heating and ablation system is configured to heat the substrate and ablate oxides on a surface of the substrate.

Abstract: A 3D printing system includes an ejector configured to receive a build material. The ejector includes a nozzle. The ejector is configured to eject a plurality of drops of the build material through the nozzle. The 3D printing system also includes a substrate positioned below the nozzle. The drops fall toward the substrate after being ejected from the nozzle. The drops form a 3D object on the substrate. The 3D printing system also includes a power source configured to generate an alternating electrical current. The 3D printing system also includes an electrode configured to generate a plasma in response to receiving the alternating electrical current. The drops, the 3D object, the substrate, or a combination thereof are positioned at least partially within the plasma.
