  • Patent number: 10663773
    Abstract: The spin-Hall effect can be used to modulate the linear polarization of light via the magneto-optical Kerr effect. A central area of an outer surface of an added layer atop a spin Hall material is illuminated while simultaneously passing a modulated electric current through the material, so that reflected light has a new linear polarization that differs from the initial linear polarization to a degree depending on the amplitude of the modulated electric current.

  • Patent number: 10648058
    Abstract: A system and method of providing metal comprising objects via additive manufacturing techniques using an RES mixture. The RES process mixes a precursor compound and a chemical agent which thermally decomposes to form typically CO, H2, NHx, or some other reducing agent. Using the RES mixture, the additive manufacturing device reproduces an object from a sliced object model file layer-by-layer. Heat is applied to the patterned RES mixture to thermally decompose the chemical agent and reduce the precursor compound to a reduced metal species. This heating and reduction transforms the RES mixture from a general paste having little to no shear strength to an solid form exhibiting a much greater shear strength, allowing layer-by-layer generation of 3D object components.

  • Patent number: 10639847
    Abstract: A method and apparatus for volumetric manufacture of three-dimensional physical objects from a precursor material based on plans, specifications, or virtual models. A build domain is provided comprising an enclosed three-dimensional wire grid in which the wires are connected to one or more electric power sources configured to controllably and addressably apply power to one or more individual wires to cause the wires to dissipate heat produced by Joule heating to the surrounding precursor material situated within the build domain, and to further allow for the control of the three-dimensional heat distribution and accordingly temperature distribution within the build domain. By activating and deactivating one or more predetermined subsets of the wires in the build domain, the precursor can be caused to melt and/or solidify so as to form a three-dimensional object within the build domain.
