  • Patent number: 10760271
    Abstract: This invention is an additively manufactured wall panel using computer aided design (CAD) and computer aided manufacturing (CAM) to design and manufacture multi-colored and multi-layered wall panels. This results in a variety of highly attractive, multi-colored wall panel faces ranging from brick, colored grout lines and multi-colored stones to multi-colored geometric designs. The design and manufacturing process greatly reduces the amount of precast cementitious materials by efficiently using higher quality materials. This reduces cost and weight while simultaneously producing a much more comprehensive, multi-functional wall panel complete with an interior frame, exterior insulation and an air, vapor and moisture barriers.

  • Patent number: 10751933
    Abstract: The disclosed embodiments provide a system that forms a three-dimensional (3D) nanostructure through 3D printing. During operation, the system performs a 3D printing operation that uses multiple passes of a scanning probe microscope (SPM) tip to deliver an ink to form the 3D nanostructure, wherein the ink includes both a positively charged polyelectrolyte (PE) and a negatively charged PE. While delivering the ink, the SPM tip is loaded with the ink and moved to a target location to deposit the ink. Finally, after the multiple passes are complete, the system cures the 3D nanostructure to remove excess positive or negative charges from the 3D nanostructure.

  • Patent number: 10737437
    Abstract: A method and apparatus for making a three-dimensional object by solidifying a photohardenable material are shown and described. A photohardening inhibitor is admitted into a surface of a photohardenable material through a flexible film to create a “dead zone” where little or no solidification occurs. The dead zone prevents the exposed surface of the photohardenable material from solidifying in contact with the film. The inhibitor causes the film to deform along the build axis, thereby creating a non-planar interface between the photohardednable material and the film. A method is provided to compensate the three-dimensional object data based on the deformation of the film.

  • Patent number: 10676219
    Abstract: A system and process of printing a package of expanded material (e.g., expanded starch, foam or other expanded material). The expanded material can be heated and extruded, poured, sprayed, or otherwise applied in malleable form that sets up to become a porous protective covering for an item to be packaged. In an example, a layer of expanded material is laid down, and the item in a protective covering (e.g., a plastic bag, sleeve, coating, etc.) is positioned on the layer of expanded material. Additional layers or expanded material may be applied, thereby encasing the item. The top surface of the expanded material may be flattened, such as by operation of a roller, press, or cutter. The top surface may be sprayed with a shellac sealant, paint, or other coating, to allow printing of a label on the top surface.
