  • Patent number: 11312049
    Abstract: A 3D printing system applies colored powders (e.g., primary colors, white, black, cyan, magenta, yellow, fluorescent colors, metallic) in printed polymer layers for forming a colored 3D object. The system may stabilize a powder layer or color sub-layers thereof, for example with one or more of heat, pressure, and/or high-intensity light. On each layer, powders of various colors may be sequentially deposited in a halftone pattern and stabilized, so as to create a part with a specified arrangement of colors throughout its structure. Benefits include more stable color than strategies involving jetting colored fluids. The arrangement of color on the interior of the part could provide functional or traceability benefits for specific applications. The examples allow for depositing a greater quantity of powder on each fiber base or substrate, decreasing the ratio of fiber to powder and increasing production speed.

  • Patent number: 11161334
    Abstract: Methods for placing an indicia on a composite structure generally include printing the indicia on a first film surface of a coating film, with the coating film being in a partially cured state at the time the printing the indicia is performed, and positioning the coating film on a partially cured composite structure such that a second film surface of the coating film faces and is positioned against a surface of the composite structure, with the second film surface being opposite the first film surface. Finally, the coating film and the composite structure may then be co-cured. Systems for printing an indicia on a composite structure generally include the coating film, a printer configured to print the indicia on the first film surface of the coating film, a securement configured to secure the coating film during printing, and a curing device for co-curing the coating film and the composite structure.

  • Patent number: 11148437
    Abstract: An ejecting apparatus includes an ejection control unit configured to cause a first ejecting unit among ejecting units (301) configured to move in a main-scanning direction, to eject a liquid; an irradiating unit (400) divided into a plurality of irradiating blocks (401) in a sub-scanning direction; an irradiation control unit configured to turn off an irradiating block corresponding to the first ejecting unit. A first distance (Y) between a downstream end of the first ejecting unit in the sub-scanning direction and an upstream end of an irradiating block is larger than a second distance (C) by which the irradiating block irradiates a recording medium outside from an end of an emission surface of the irradiator block in the sub-scanning direction. The irradiation control unit is configured to cure the liquid by causing the irradiating block positioned downstream of the turned-off irradiating block corresponding to the first ejecting unit, to emit the activation energy ray.
