  • Publication number: 20160332373
    Abstract: Methods and systems (2) are disclosed for making articles (114) by three-dimensional printing. The methods include selectively printing by jet deposition on successive layers (4) of a build material powder (10) at least one of a first binder fluid and a second binder fluid. At least one of the first and second binder fluids includes a particulate matter (16) having mean particle size diameter which is less than that of the build material powder (10). The first binder fluid is characteristically different from the second binder fluid. The particulate matter (16) selectively deposited with a binder fluid can be used to locally tailor the physical properties of the article (114), e.g. by alloying with the build material powder, increasing densification, acting as a local infiltrant or infiltrant stop during heat treatment, locally modulating the local stress fields (e.g. by a mismatch of thermal coefficients of expansion), etc.

  • Publication number: 20160325495
    Abstract: Methods and systems (20) are disclosed for making articles by three-dimensional printing. The methods include three-dimensionally printing articles by selectively jet-depositing a particle-bearing binder fluid (14) upon successive layers (4) of a build material powder (10) such that the particles (16) deposited with the binder fluid (14) increase the apparent density of the as-printed article. The particulate matter (16) of the binder fluid (12) is smaller than the mean particle size of the build material powder (10). Preferably, this jet-deposited particulate matter (16) has a mean particle size that is larger than about 1 to and smaller than or equal to 50 microns. The jet-deposited matter (16) acts to fill in the interparticle interstices of the build material powder (10) thereby simultaneously increasing the density of the printed article and improving its surface roughness and contour resolution, which in turn, improves the surface finish of the final article.

  • Publication number: 20160243621
    Abstract: Methods are disclosed for making a hot isostatic pressing container for hot isostatic pressing a powder material to form an article comprising three-dimensionally printing the container from a build powder, the container having a cavity for receiving the powder material and an outer section having an outer surface, the cavity having a surface and being shaped and sized so that hot isostatic pressing the container with the powder material within the cavity results in the production of the article. Methods are also disclosed for making the hot isostatically pressed article using the container.

  • Publication number: 20160052054
    Abstract: Apparatuses are disclosed for three-dimensionally printing reactive materials which utilize a powder spreading step followed by a binder-jet deposition step. Some such apparatuses include a binder jet three-dimensional printing device, a curing device, and a depowdering device contained within an environmental enclosure which provides an inert atmosphere sufficient to allow a reactive material to be used as a build material without fire or explosion hazards. Some such apparatuses include one or more conveying systems for moving a removable build box among the various devices. Environmental enclosures having unique designs and features are disclosed.

  • Patent number: 8071206
    Abstract: A blast energy mitigating composite useful for protecting a surface or an object from a blast, shock waves, or stress waves caused by a sudden, violent release of energy is described. Certain configurations of the blast energy mitigating composite may include energy mitigating units contained in an energy mitigating matrix. If desired, various reinforcement layers may be incorporated on or within the energy mitigating composite. The energy mitigating units may comprise a porous energy mitigating material such as carbon foam.

  • Patent number: 7931961
    Abstract: A composite exhaust flue which may be used to shield an area or object from convective, conductive, or radiated heat transfer from hot exhaust combustion gases is described. In certain embodiments, the composite exhaust flue may be used to protect structures from hot exhaust gases and particles such as those produced by cars, trucks, ships, boats, jets, rockets, as well as other vehicles with internal combustion engines, turbines, or rocket motors. In some embodiments, a composite exhaust flue may comprise a ceramic fiber reinforced ceramic composite high temperature face sheet positioned over an insulating layer and a structural support layer comprising a rigid, porous foam material.

  • Patent number: 7824645
    Abstract: A high density carbon material produced from coal is described. The carbon material may have a density ranging from about 1.0 g/cc to about 1.6 g/cc and may have a crush strength of up to about 20,000 psi. The high density carbon material is produced by slowly heating comminuted swelling bituminous coal particles under pressures of 400 psi to about 500 psi to a first temperature at about the initial plastic temperature of the coal. The material is held at this temperature for a period of time sufficient to provide for a uniform temperature throughout the coal. The material is then heated to a second temperature for a period of time sufficient to provide for the coal achieving an essentially uniform temperature. The resulting product is a three-dimensional, self-supporting carbon that has a substantially continuous carbon matrix defining grain boundaries within the carbon matrix.

  • Patent number: 7766984
    Abstract: A method for increasing the yield of carbon foam is described. The method includes placing a foaming sheet over the top surface of the material to be foamed. In certain embodiments, the foaming sheet is placed over the top surface of particulate coal prior to and during the foaming process. In some embodiments the foaming sheet is a smooth, continuous sheet, such as aluminum foil or the like. The resulting carbon product includes an increased amount of usable carbon foam.
