Abstract

A manufacturing method of a structure includes, in this order: providing a layer constituted by a support member and a modeling layer by bringing a regulating surface of a regulating member into contact with the modeling layer provided on a surface of an intermediate transfer member, pouring a material for the support member which becomes the support member to fill the periphery of the modeling layer while the regulating surface abutting the modeling layer, and solidifying the material for the support member; removing the regulating member from the layer constituted by the support member and the modeling layer.

First claim

What is claimed is:

1. A manufacturing method of a structure in which the structure is manufactured by laminating a modeling layer which becomes the structure while supporting a structure under formation with a support member, the method comprising, in this order:
preparing the modeling layer provided on a surface of an intermediate transfer member;
bringing a regulating surface of a regulating member for regulating a surface of the modeling layer into contact with a surface of the modeling layer which is an opposite side of the intermediate transfer member,
loading a material for the support member which becomes the support member which is different from a material forming the modeling layer to fill a gap between the intermediate transfer member and the regulating member in the periphery of the modeling layer while the regulating member abuts the surface of the modeling layer, and solidifying the material for the support member;
removing the regulating member from the layer constituted by the support member and the modeling layer; and
transferring the layer formed by the support member and the modeling layer exposed by removing the regulating member to a structure under formation.

2. The manufacturing method of a structure according to claim 1 , wherein, in preparing the modeling layer, the modeling layer is formed by providing a modeling material which becomes the modeling layer on a surface of the intermediate transfer member and bringing the material which becomes the modeling layer and the regulating surface into contact.

3. The manufacturing method of a structure according to claim 2 , wherein the modeling material solidifies when illuminated by UV light, and the modeling layer is formed by illuminating UV light on the modeling material in a state in which the regulating surface and the surface of the modeling layer on the opposite side abut each other.

4. The manufacturing method of a structure according to claim 3 , wherein UV light is made to illuminate the modeling material through the regulating surface of the regulating member.

5. The manufacturing method of a structure according to claim 1 , wherein, in preparing the modeling layer, the modeling material is provided on the surface of the intermediate transfer member by ejecting the modeling material which becomes the modeling layer from a liquid ejection head which ejects the liquid through an ejection port to the surface of the intermediate transfer member.

6. The manufacturing method of a structure according to claim 1 , wherein the material for the support member is paraffin wax.
