INK COMPOSITION AND PROCESS FOR PRODUCING PRINTED OBJECT
The ink composition according to the present invention contains both an adhesiveness-imparting component whereby adhesiveness to printing media is imparted and a rigidity-imparting component.
[Problem] According to the present invention, it is possible to more appropriately flatten an ink layer during molding of a three-dimensional object, for example. [Solution] Provided is a molding device for molding a three-dimensional object by a laminate molding method, the molding device being provided with: an inkjet head; a flattening means; a molding base; a main scanning drive unit; and a laminating direction drive unit for changing the distance between head bases, which is the distance between the ink jet head and the molding base. In an operation for forming a one ink layer, a main scanning operation in which the inkjet head is moved in one direction is performed several times on the same position of the three-dimensional object being molded. Regarding the distance between the head bases, in the operation for forming the one ink layer, the distance between the head bases during the main scanning operation performed later is made larger than the distance between the head bases during the main scanning operation performed earlier.

THREE-DIMENSIONAL MOLDED OBJECT PRODUCTION METHOD AND MOLDING DEVICE
In order to increase the thickness of a decorative surface layer without markedly losing color shade or gradation expression, this production method for three-dimensional molded objects uses a white material 15, at least one colored material 13 other than white, and a clear material. The at least one colored material 13 and the clear material 14 are used and a decorative surface layer 11 comprising a plurality of layers having layered therein a plurality of laminates is formed; at least one laminate is formed using the white material 15, in an area on the decorative surface layer 11 side in an internal molded area 12 constituting at least the lowermost layer of the decorative surface layer 11 or the interior of the three-dimensional molded object; each of the plurality of layers constituting the decorative surface layer 11 is formed using the same color; and, by laminating the plurality of layers, the depth of color visible when the three-dimensional molded object is observed is adjusted so as to be deeper than the depth of color in each layer included in the plurality of layers.

THREE-DIMENSIONAL MOLDED OBJECT PRODUCTION METHOD AND MOLDING DEVICE
In order to be able to see an intended color from any viewing perspective and in order to achieve coloration or a painted decorative interior, in any cross-sectional surface, this three-dimensional molded object production method molds three-dimensional molded objects by: discharging a molding material to form layers corresponding to cross-sectional surfaces obtained by cutting a molded target object in a plurality of parallel planes, and stacking the layers sequentially. The production method for three-dimensional objects is characterized by: using a white material 15 and at least one decorative material 13 other than white as the molding material, said white material and decorative material solidifying in accordance with prescribed conditions after being discharged from a nozzle; and mixing the decorative material 13 and the white material 15 and forming a layer.

THREE-DIMENSIONAL OBJECT MODELING METHOD AND 3D PRINTER
[Problem] The purpose of the present invention is to provide a three-dimensional object modeling method which can suppress the occurrence of a streak in a three-dimensional object, such streak being parallel to a primary scanning direction. [Solution] A three-dimensional object modeling method includes: a slice information calculation step (step ST23) of dividing the 3D data of the three-dimensional object into a plurality of layers and then calculating the cross-section slice information of each layer; and a single layer forming step (step ST27) of forming each layer on the basis of the cross-section slice information. The single layer forming step (step ST27) is repeated multiple times. The single layer forming step (step ST27) includes a printing step (step ST27A) of forming a one-line printing pass by causing a discharge unit to move in a primary scanning direction and discharging ink onto a work surface. In the single layer forming step, the printing step and a secondary scanning direction movement step (step ST27B) of causing the work surface to move in a secondary scanning direction are alternately performed. Printing passes are formed so that, among adjacent layers in the layer build-up direction, at least a portion of the boundaries between printing passes is offset in the secondary scanning direction.

METHOD FOR FORMING THREE-DIMENSIONAL OBJECT, AND THREE-DIMENSIONAL PRINTER
[Problem] The purpose of the present invention is to provide a method for forming a three-dimensional object and a three-dimensional printer that are capable of suppressing the occurrence of warp stripes on the surface of the three-dimensional object. [Solution] In the method for forming a three-dimensional object according to the present invention, an ink jet printer forms a three-dimensional object on the basis of three-dimensional data including shape data for defining the shape of the three-dimensional object and surface image data that are formed from a plurality of pixels and that display an image of the surface of the three-dimensional object. The method for forming a three-dimensional object comprises the steps of surface image processing (step ST2), slice data calculation (step ST4), and unit layer formation (step ST6). In the surface image processing step (step ST2), image processing that sets the color of the ink to be injected in the pixels is performed. In the slice data calculation step (step ST4), three-dimensional data are divided into a plurality of layers and cross section slice data are calculated. In the unit layer formation step (step ST6), each layer is formed on the basis of the cross section slice data.
