In a first step, a first layer of a glass powder is spread on a surface, a computer-controlled stream of a printing fluid is directed to selected areas of the first layer in a pattern prescribed by the computer. In a second step, a further layer of the glass powder is spread over the first layer and on it, a computer-controlled stream of printing fluid is directed to selected surfaces of the second layer in a pattern prescribed by the computer, the two steps are repeated until the blank is formed. The glass powder components contain SiO2, Na2O, K2O, CaO, MgO, B2O3, BaO, Al2O3, PbO, Li2O and SrO as well as a solid binder made of dextrin.

  • Patent number: 10066119
    Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. The deposited powder bed is heated to about 50° C. to about 170° C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

  • Patent number: 10040216
    Abstract: Three-dimensional printing processes are disclosed which utilize printable fluids comprising a carrier fluid, a polymeric binder, and nanoparticles. The three-dimensional printing processes are useful for making articles from a build material powder, e.g., a ceramic, metal, metal alloy, or intermetallic powder. The nanoparticles enable low temperature interparticle bonding of the build material powder particles, e.g., by forming bridging bonds between adjacent powder particles, and/or increasing the interparticle friction between the build material powder particles to enhance the structural strength of the as-built article during a thermal treatment over at least a part of the temperature range which has as its low end the temperature at which the structural strength due to the binder becomes insubstantial and as its high end the temperature at which the structural strength due to interparticle sintering of the build material powder becomes substantial, i.e., the article's debile temperature range.
