Abstract:
1. A molding apparatus comprising: an ejection head that ejects a liquid whose curing is precipitated by receiving activation energy; a drawing stand that has a drawing surface on which cross-section patterns of a three-dimensional object as a molding target are drawn with the liquid ejected from the ejection head; an energy applying device that applies the activation energy to the liquid adhering to the drawing surface; and a molding stand on which the cross-section patterns after being applied with the activation energy are transferred from the drawing stand; wherein, on the drawing surface, a liquid repellent area is formed, the liquid repellent area has liquid repellency for the liquid, a plurality of projected lyophilic areas that are independently formed in an island shape within the liquid repellent area are arrange, the plurality of projected lyophilic areas protrude from the liquid repellant area, a lyophillicity of each top surface of the plurality of projected lyophilic areas is larger than a lyophillicity of the liquid repellent area and is larger than a lyophillicity of each side surface of the plurality of projected lyophilic areas, the ejection head ejects the liquid as a liquid droplet, and a distance between the plurality of projected lyophilic areas adjacent to each other is equal to or less than 1.25 times an outer diameter of the liquid droplet.
