    Abstract: A production method of a three-dimensionally shaped object, includes a first layer forming step of forming a first layer by using a first composition containing first powder and binder, a second layer forming step of forming a second layer by using a second composition containing second powder, third powder, and binder, and a sintering step of sintering the first powder and the second powder. In a case where the first powder and the second powder are of the same material, difference in a contraction rate between the first layer and the second layer in the sintering step is reduced by matching a filling rate of the first powder in the first composition with a total filling rate of the second powder and the third powder in the second composition and matching an average particle diameter of the first powder with an average particle diameter of the second powder.

    Abstract: A fluid material ejecting apparatus includes a material chamber to which a fluid material containing at least one of metal particles and ceramic particles is supplied, a valve seat constituting a part of the material chamber and including an ejection port, a piston movable in the material chamber in directions toward and away from the ejection port, and a driver of the piston. The driver is configured to cause the piston to contact the valve seat from a position away from the valve seat and move in the direction toward the ejection port so as to slide along the valve seat, to thereby eject the fluid material through the ejection port. Sliding surfaces of the piston and the valve seat via which the piston and the valve seat contact each other have a higher Vickers hardness than the particles contained in the fluid material.

    Abstract: A three-dimensional modeling apparatus includes a modeling portion that models a three-dimensional object by laminating material layers formed by a material having a fluid property, and executes a first modeling process that forms concave portions, which are adjacent to two or more convex portions and are recessed in comparison with the convex portions in a lamination direction in which material layers are laminated, as a result of forming a plurality of convex portions that project in the lamination direction, a second modeling process that laminates a material layer on the convex portions, and forms a material layer, which is spatially separated from the material layer laminated on the convex portions, inside the concave portions, and a third modeling process that fills the concave portions with a material layer by disposing the material on the material layer inside the concave portions.

    Abstract: A three-dimensional modeling apparatus is provided with a head unit for modeling an object by discharging a liquid into each unit grille that is defined in accordance with modeling resolutions of a cross section body in an X direction and a Y direction and a lamination interval in a Z direction, and a control unit for controlling the head unit. In the case where one or more types of the chromatic liquids are discharged into the unit grille by controlling the head unit and the spatial volume of the unit grille is not filled with the one or more types of chromatic liquids, the control unit causes the achromatic liquid to be discharged into the unit grille in addition to the one or more types of chromatic liquids so as to fill the spatial volume of the unit grille with both the chromatic liquids and the achromatic liquid.

    Abstract: A three-dimensional formation apparatus includes a head-unit which can discharge liquid in a first-direction and a control-unit which controls the head-unit. The control-unit forms a hollow on a changed portion where an outline of a cross section object is simultaneously changed in a second-direction and a third-direction towards the inside from the outline of the cross section object in the second-direction or the third-direction, in a first cross section object formation process and executes a filling process of discharging the liquid containing a second quantity which is larger than a first quantity to the hollow so as to come in contact with the cross section object formed in the first cross section object formation process, to fill at least a part of the hollow with the liquid, after the first cross section object formation process is executed and before the second cross section object formation process is executed.
