Abstract

Provided is a manufacturing method of a three-dimensional structure which manufactures a three-dimensional structure by laminating layers, the method including: forming the layers using a three-dimensional formation composition containing three-dimensional formation powders, a solvent, and a binder; discharging a binding solution containing a binding agent to the layers; and performing a permeation prevention step of preventing the solvent from permeating the layers, at least on a part of the layers to which the binding solution is discharged. It is preferable that the permeation prevention process is selectively performed with respect to an area of the layers to which the binding solution is not discharged.

First claim

What is claimed is:

1. A manufacturing method of a three-dimensional structure which manufactures a three-dimensional structure by laminating layers, the method comprising:
forming the layers using a three-dimensional formation composition containing three-dimensional formation powders, a solvent, and a binder;
discharging a binding solution containing a binding agent to the layers; and
performing a permeation prevention step of preventing the solvent from permeating the layers, at least on a part of the layers to which the binding solution is discharged.

2. The manufacturing method of a three-dimensional structure according to claim 1 ,
wherein the permeation prevention process is selectively performed with respect to an area of the layers to which the binding solution is not discharged.

3. The manufacturing method of a three-dimensional structure according to claim 1 ,
wherein the permeation prevention process is performed by applying a permeation prevention agent containing the binder.

4. The manufacturing method of a three-dimensional structure according to claim 3 ,
wherein the application of the permeation prevention agent is performed by any one of a group consisting of an ink jet method, a squeegee method, a transfer method, or a sublimation method.

5. The manufacturing method of a three-dimensional structure according to claim 1 ,
wherein the solvent is water-soluble.

6. A three-dimensional structure which is manufactured by the manufacturing method of a three-dimensional structure according to claim 1 .

7. A three-dimensional structure which is manufactured by the manufacturing method of a three-dimensional structure according to claim 2 .

8. A three-dimensional structure which is manufactured by the manufacturing method of a three-dimensional structure according to claim 3 .

9. A three-dimensional structure which is manufactured by the manufacturing method of a three-dimensional structure according to claim 4 .

10. A three-dimensional structure which is manufactured by the manufacturing method of a three-dimensional structure according to claim 5 .
