An information processing device includes a display and a second controller that causes the display to display an edit screen including a first image edit area and a second image edit area for receiving an edit to an image. The second controller causes a stair image, which resembles the shape of a media tray to be inserted into a printing device, to be displayed as a background image of the edit screen. Images displayed in the first image edit area and the second image edit area are associated with images to be printed on a plurality of print media loaded in the media tray, the association being based on the location of the stair image relative to the first image edit area and the second image edit area.

A three-dimensional shaping apparatus includes a discharge portion discharging a shaping material, a shaping stage on which the shaping material discharged from the discharge portion is stacked, a temperature adjustment portion provided in the shaping stage to adjust a temperature of the shaping stage, and a control portion. The control portion stacks the shaping material on the shaping stage to shape and cure a three-dimensional shaping object while changing a relative position between the discharge portion and the shaping stage, and then, heats or cools a portion of the cured three-dimensional shaping object in contact with the shaping stage by controlling the temperature adjustment portion to adjust the temperature of the shaping stage.

Three-dimensional shaping apparatus and method of manufacturing three-dimensional shaping object

A method for manufacturing a three-dimensional shaped object includes: a first shaping step of forming a first layer in contact with a stage provided with a plurality of recessed portions by changing a relative position between a discharge unit and the stage while discharging a molten material from the discharge unit toward the stage; and a second shaping step of stacking one or more layers on the first layer by changing the relative position between the discharge unit and the stage while discharging the molten material from the discharge unit toward the first layer. The stage has a first region where an outer peripheral edge of the first layer is formed and a second region different from the first region in a region where the first layer is formed, and in the first shaping step, the first layer is formed by making a first supply amount which is a supply amount of the molten material supplied from the discharge unit to the first region per unit area larger than a second supply amount which is a supply amount of the molten material supplied from the discharge unit to the second region per unit area.

Provided is a three-dimensional shaping device including a melting unit configured to melt a material into a shaping material, and a nozzle configured to discharge the shaping material supplied from the melting unit toward a stage. The melting unit includes a screw configured to rotate about a rotation axis and having a groove forming surface in which a groove to which the material is supplied is formed, a heating unit configured to heat the material supplied to the groove, a barrel having a facing surface that faces the groove forming surface and provided with a communication hole that communicates the facing surface with the nozzle, and a discharge amount adjustment mechanism provided in the communication hole and configured to adjust a flow rate of the shaping material discharged from the nozzle.
