  • Patent number: 11034069
    Abstract: A problem exists of prohibitively high costs associated with molds for small run, legacy, or prototype injection molded parts. Further, the lead time on molds is currently on the order of about two weeks. A mold is provided that is formed from three-dimensional printing. The mold includes a series of air and/or water cooling channels to limit thermal stresses to the mold. Additionally, a series of coatings is added to the surface of a 3D printed mold to extend the lifetime of the mold and increase the performance of the mold. The coatings perform a function other than to define a shape of an injection cavity, such as improving thermal conductivity, providing a thermal barrier between the injection material and the mold body, or improving the detachment of the final mold product from the mold body.

  • Patent number: 10053190
    Abstract: An article with controllable wettability includes a substrate and a layer of a composite material supported on the substrate. The layer has an exposed surface and the composite material includes particles that have controllable polarization embedded fully or partially in a matrix. A controller is operable to selectively apply a controlled variable activation energy to the layer. The controllable polarization of the particles varies responsive to the controlled variable activation energy such that a wettability of the exposed surface also varies responsive to the controlled variable activation energy.

  • Publication number: 20160172327
    Abstract: The present disclosure provides improved systems and methods for low-temperature bonding and/or sealing with spaced nanorods. In exemplary embodiments, the present disclosure provides for the use of metallic nanorods to bond and seal two substrates. The properties of the resulting bond are mechanical strength comparable to adhesives, impermeability comparable to metals and long term stability comparable to metals. The bond may be attached to any flat substrate and superstate with strong adhesion. In certain embodiments, the bond is achieved at room temperature with only pressure or at a temperature above room temperature (e.g., about 150° C. or less) and reduced pressure. Exemplary bonds are both mechanically strong and substantially impermeable to oxygen and moisture.
