Abstract:
A treatment-liquid application device includes a treatment-liquid container, a liquid supply unit, a liquid chamber unit, a treatment-liquid carrier, a transport unit, a treatment-liquid applicator, and a partition. The partition is disposed in an area of the chamber unit defined by an imaginary entry plane, an imaginary exit plane, a carrying surface of the carrier, and a bottom face of the chamber unit. The entry plane includes an entry line at which the carrying surface enters treatment liquid in the chamber unit, and vertically extends from the entry line. The exit plane includes an exit line at which the carrying surface exits from the liquid in the chamber unit, and vertically extends from the exit line. The partition extends in a longitudinal direction of the carrier and has an edge portion adjacent to the carrying surface.
Abstract:
An image forming apparatus including an image forming device forming an image on a surface of a recording material; a recording material passage; a treatment liquid applicator including a tray containing a treatment liquid, a first roller applying the treatment liquid to the surface of the recording material, and a second roller drawing the treatment liquid from the tray to supply the treatment liquid to the first roller; a liquid level inclination detector detecting whether the surface of the treatment liquid is inclined; a treatment liquid supplying device supplying the treatment liquid to the tray; and a controller connected with liquid level detector and the treatment liquid supplying device. The controller stops the operation of the treatment liquid supplying device when determining according to the detection result of the liquid level detector that the surface of the treatment liquid is inclined in a predetermined amount or more.

Abstract:
An apparatus for fabricating a three-dimensional object includes a fabrication stage and a flattener. A fabrication layer in which powder particles are bound together is formed layer-by-layer on the fabrication stage. The flattener relatively moves in a moving direction along a stage surface of the fabrication stage and flattens a surface of powder on the fabrication stage to form a powder layer. The fabrication stage and the flattener are arranged to be relatively movable in a height direction. In formation of the powder layer on the fabrication layer formed on the fabrication stage, the apparatus performs an operation to increase a distance between the flattener and the fabrication stage in the height direction when the flattener moves to a position near an edge of the fabrication layer in the moving direction.
Abstract:
A powder removal device includes an air spray configured to blow an airflow including powder against a three-dimensional object including a plurality of fabrication layers, to remove unbonded powder from the three-dimensional object. Each of the plurality of fabrication layers includes bonded powder.
Abstract:
A three-dimensional printing system includes a reservoir, a feeder, a solidifier, and a controller. The reservoir is configured to store powder, the powder being to be solidified inside the reservoir to form a three-dimensional object. The feeder is configured to move the powder from a predetermined location in a predetermined conveying direction, thereby feeding the powder to the reservoir. The solidifier is configured to perform a process of solidifying the powder in the reservoir in accordance with a control signal. The controller is configured to generate the control signal so as to form a first auxiliary object between the three-dimensional object and a wall surface of the reservoir, the wall surface being at a position downstream from the three-dimensional object in the conveying direction.
Abstract:
A method for molding a three-dimensional object, includes building up layers formed of bonded powder to form a three-dimensional object; and forming a support below the three-dimensional object. The method is performed by a three-dimensional object molding apparatus that includes a powder lamination molding apparatus to form a three-dimensional object by building up layers formed of bonded powder; and a molding data generator to generate data for each layer of the three-dimensional object that the powder lamination molding apparatus laminates, in which a support is formed below the three-dimensional object.
