  • Patent number: 8814954
    Abstract: The method for manufacturing products having a metal surface by imparting microfeatures onto the metal surface. The method if further described as the steps of: creating a transfer tool from a microstructured intermediate fabricated from a microstructured prototype having microfeatures; and, transferring the microfeatures to said metal surface using the transfer tool.
    Type: Grant

  • Publication number: 20110311764
    Abstract: A microstructure disposed on a surface carried by an object comprising: a first set of microfeatures carried by the object wherein said first set of microfeatures causes the surface of the object to exhibit physical properties differing from physical properties exhibited by a non-microstructured surface; and, a second set of microfeatures carried by said surface wherein said second set of microfeatures causes the surface of the object to exhibit physical properties differing from physical properties exhibited by the non-microstructured surface and by said first set of microfeatures.

  • Publication number: 20110266724
    Abstract: A method of manufacturing a production part having microstructured features comprising the steps of fabricating a microstructured prototype having microstructured features, manufacturing a microstructured intermediate from the microstructured prototype so that the microstructured intermediate carries a negative of the microstructured features, attaching the microstructured intermediate to a manufacturing tool thereby providing microstructured features on a manufacturing tool, providing feedstock containing material from the group comprising of: metal, ceramic, binder, and any combination of these and manufacturing the production part from the feedstock, using the manufacturing tool and using a process from the group consisting of: compression molding, roll forming, stamping, embossing, extrusion injection molding, and any combination of these.
