  • Methods of Forming Parts Using Laser Machining
    Publication number: 20230201968
    Abstract: Embodiments are directed to the formation micro-scale or millimeter scale structures or methods of making such structures wherein the structures are formed from at least one sheet structural material and may include additional sheet structural materials or deposited structural materials wherein all or a portion of the patterning of the structural materials occurs via laser cutting. In some embodiments, selective deposition is used to provide a portion of the patterning. In some embodiments the structural material or structural materials are bounded from below by a sacrificial bridging material (e.g. a metal) and possibly from above by a sacrificial capping material (e.g. a metal).

  • Batch Methods of Forming Microscale or Millimeter Scale Structures Using Electro Discharge Machining Alone or In Combination with Other Fabrication Methods
    Publication number: 20150021299
    Abstract: Embodiments are directed to forming three-dimensional millimeter scale or micro-scale structures from single or multiple sheets or layers of material via electro discharge machining (EDM). In some embodiments, the electrodes are formed by single layer or multi-layer, single material or multi-material deposition processes. In some embodiments single electrodes form a plurality of parts or structures simultaneously. In some embodiments a sacrificial bridging material is used to hold parts together during and after EDM processing.
