  • Patent number: 11858209
    Abstract: A fabricating apparatus includes a powder layer forming device, a fabrication liquid discharge device, and processing circuitry. The powder layer forming device is configured to form a powder layer. The fabrication liquid discharge device is configured to discharge fabrication liquid onto the powder layer. The processing circuitry is configured to control the fabrication liquid discharge device to discharge the fabrication liquid with a first kinetic energy and then discharge the fabrication liquid with a second kinetic energy higher than the first kinetic energy.

  • Patent number: 11225017
    Abstract: Disclosed is a three-dimensional object shaping apparatus for forming an object with a desired shape in a three-dimensional space represented by a three-dimensional orthogonal coordinate system of XYZ. The three-dimensional object shaping apparatus includes a light source; a drive mechanism to move the shaping surface parallel to an XY plane in a Z axis direction; an optical scanning unit to scan light emitted from the light source along a Y axis direction perpendicular to the Z axis; and a rotation mechanism to rotate one of the optical scanning unit and the shaping surface relative to each other with respect to the Z axis as a rotation axis, where a pattern of the light to be applied to the shaping surface is controlled by a combination of a rotation of the shaping surface performed by the rotation mechanism and the scanning of the light performed by the optical scanning unit.

  • Publication number: 20210339469
    Abstract: An apparatus configured to model a three-dimensional modeled object, includes a carrier, an energy applying unit, and a flying unit. The carrier is configured to carry a modeling material. The energy applying unit is configured to apply energy to a surface of a modeled object. The flying unit is configured to fly the modeling material carried on the carrier toward the surface of the modeled object, the energy being applied to the surface.

  • Patent number: 11156498
    Abstract: An object detector including a light-emitting system to emit light to an object, a light detector, a signal detector, and a threshold adjuster. The light detector receives the light emitted from the light-emitting system and reflected by the object, and output a signal. The signal detector detects the signal output from the light detector based on a threshold value of voltage. The threshold adjuster changes the threshold value between when the light-emitting system emits light to a part of a light-emission range of the light-emitting system and when the light-emitting system emits light to other part of the light-emission range other than the part of the light-emission range.
