By irradiating the desired portion with light (electromagnetic wave) 5 from the light source 4 to heat the portion, a latent image is formed on the portion. At this stage, only the latent image portion has hydrophilicity and lipophilicity, and other areas remain water-repellent and oil-repellent.

Finally, as shown in FIG. 1B, the desired coating liquid 6 is brought into contact with the latent image portion and then dried, and then the latent image portion is dried as shown in FIG.

If the result of applying the coating liquid is different from the desired result or if you want to check the adhesion state of the coating liquid, remove the applied coating liquid and then erase part or all of the latent image once formed. There is a need to. However, if the coating liquid that you want to finally apply to the three-dimensional object cannot be removed, you cannot redo it, so if the three-dimensional object is valuable, you can remove it experimentally to confirm the state of application of the coating liquid. It is preferable to use a different coating solution.

To erase the latent image, after removing the coating liquid on the portion of the recording body where the latent image needs to be erased, the surface of the recording body on the removed portion is heated without bringing a substance to be a liquid into contact therewith.

According to this method, since the conductive material can be applied to the inner and outer surfaces of the three-dimensional object, it is possible to easily manufacture the heating element even with the existing heat-resistant three-dimensional object, and to obtain various shapes and sizes. It is possible to fabricate a heating element having a different shape or a complicated shape.

The resistance value of this heating element can be easily set to a desired value by changing the concentration of the conductive material in the coating liquid. Further, since the thickness of the recording body layer 2 can be formed as very thin as 100 Å, even if the heat generation temperature of the heating element exceeds the heat resistant temperature of the recording body layer 2, the conductive material adhered to the recording body layer 2 is It has the advantage that it hardly peels off or breaks.

By the way, when a plurality of kinds of coating liquids are applied to the same three-dimensional object, when the respective coating liquids are desired to be overlapped on the recording material layer, when they are not desired to be overlapped, when they may be overlapped, and when they are overlapped. Sometimes you don't have to.

Of these, when it is desired to overlap and when it is not desired to overlap, a recording layer must be newly formed in a region where another coating liquid has already adhered each time the coating liquid is changed. In this case, multiple types of coating are performed by repeating a series of steps consisting of forming a recording material layer on a three-dimensional object, forming a latent image on the recording material layer, contacting the coating liquid, and drying the coating liquid adhering portion.
