  "title": "Making Strong Ceramic-Metal Parts with Special 3D Printing Powder",
  "original_title": "Additive manufacturing material for powder rapid prototyping manufacturing",
  "summary": "Fujimi Inc.'s patent describes a special 3D printing powder made of ceramic and metal particles combined into granulated units, designed to efficiently produce high-density, strong parts.",
  "what_it_does": "This patent describes an additive manufacturing material, essentially a specialized powder, for creating high-density objects through 3D printing. It combines a first powder, which is mainly ceramic, with a second powder, which is mainly a specific metal or metal alloy (Claim 9). These two powders are not just mixed; they form 'granulated particles' where the tiny 'primary particles' of ceramic and metal are bound together, leaving small spaces or 'voids' (Claim 9). The ceramic particles are also required to be smaller than the metal particles, specifically their average diameter (D1) must be half or less than half of the metal particles' average diameter (D2) (Claim 9). The metal content in these granulated particles must be between 15% and less than 90% by mass (Claim 9). For example, this material could be used to 3D print a durable, heat-resistant component for an engine or a wear-resistant tool.",
  "what_it_does_not_cover": [
    "Does not cover additive manufacturing materials where the ceramic powder's average particle diameter is more than half the metal powder's average particle diameter (D1 > 0.5 * D2).",
    "Does not cover materials where the ceramic and metal powders are simply mixed, rather than forming 'granulated particles' where primary particles are three-dimensionally bound through voids.",
    "Does not cover materials where the metal component is less than 15% or 90% or more by mass of the total ceramic and metal powder content.",
    "Does not cover materials using metal elements or alloys not explicitly listed in claim 9 or claim 10, such as certain rare earth metals or specific custom alloys.",
    "Does not cover materials where either the first powder is not mainly ceramic or the second powder is not mainly metal."

  "abstract": "A molding material is provided which, despite containing a ceramic, enables efficient molding for producing high-density molded articles. The present invention provides a molding material to be used in powder laminate molding. This molding material contains a first powder which contains a ceramic, and a second powder which contains a metal. Further, the first powder and the second powder configure granulated particles. Ideally, the ratio of the content of the second powder to the total content of the first powder and the second powder is greater than 10 mass % and less than 90 mass %.",
