A method of manufacturing a carbon nanotube (CNT) composite material structure is provided. The method includes providing ink, in which a CNT composite material including a CNT and a rheological modifier is dispersed, to a nozzle, positioning the nozzle at a predetermined point on a substrate, and moving the nozzle along a predetermined path on the substrate while discharging the ink from the nozzle by surface tension of a meniscus formed at a leading end of the nozzle and printing a CNT composite material pattern corresponding to a movement path of the nozzle. In printing the CNT composite material pattern, the pattern is stacked as the CNT composite material by evaporation of a solvent within a meniscus formed by the ink extruded from the nozzle between the nozzle and the substrate.

Carbon nanotube (CNT) ink includes a CNT, a rheological modifier for controlling a flow of the CNT, and a solvent. The CNT ink exhibits a liquid-like behavior under shear stress of 10.sup.−1 to 10 Pa. A loss modulus of the CNT ink may have a larger value than that of storage modulus under shear stress of 10.sup.−1 to 10 Pa. A content of the CNT may be 1 to 20 wt %. A content of the rheological modifier in the CNT ink may be 5 to 40 wt %. A weight ratio of the content of the CNT and the content of the rheological modifier in the CNT ink may be 1:1 to 1:5. The solvent may have a boiling point of 100° C. or less.

Such internal decoration is implemented that an object looks a target color as viewed in any direction, and that the object is colored and has image depiction in any cross-section. A method is provided for producing a three-dimensional object by extruding a build material to form a layer corresponding to each of cross-sections obtained by slicing a target object by a plurality of parallel planes, and depositing such layers in sequence so as to form the three-dimensional object. A white material 15 and one or two or more decoration materials 13 of colors other than white, which solidify wider a predetermined condition after extruded from nozzles, are used as the build material. The decoration materials 13 and the white material 15 are mixed to form the layer.
