  • Patent number: 11926091
    Abstract: The invention relates to a process for fabricating complex mechanical shapes, and in particular to fabricating complex mechanical shapes using a pressure-assisted sintering technique to address problems relating to variations in specimen thickness and tooling, or densification gradients, by 3-D printing of a polymer model that is surrounded by and filled with sintering powder material, wherein the 3-D polymer model decomposed into a graphite interface layer and facilitates release of the cast, e.g. metal, metal-alloy, ceramic, etc., manufactured item.
    Type: Grant
    Filed: March 27, 2019
    Date of Patent: March 12, 2024
    Assignees: UNITED STATES OF AMERICA has certain rights in the invention from DOE Grant No. DE-SC0008581, San Diego State University
    Inventors: Eugene Olevsky, Charles Maniere
  • Patent number: 11648706
    Abstract: The invention relates to a process for fabricating complex mechanical shapes from metal or ceramic, and in particular to fabricating complex mechanical shapes using a pressure-assisted sintering technique to address problems relating to variations in specimen thickness and tooling, or densification gradients, by 3-D printing of a sacrificial, self-destructing powder mold is created using e.g. alumina and swellable binders such as polysaccharides. The binder-free sintering powder that forms the manufactured item is injected into the mold, and high pressure is applied. The powder assembly can then be sintered by any pressure assisted technique to full densification and the self-destructing mold allows the release of the fully densified complex manufactured item.
