Molding method and molding apparatus

Abstract

A molding method includes drawing cross-section elements of a three-dimensional object as a molding target on a drawing surface of a drawing stand with a liquid whose curing is precipitated by receiving activation energy as cross-section patterns; applying the activation energy to the liquid configuring the cross-section patterns in a state in which the cross-section patterns is pinched between the drawing stand and a molding stand; and detaching the cross-section patterns after being applied with the activation energy from the drawing stand and transferring the cross-section patterns to the molding stand side, wherein the drawing surface has a liquid repellent area that is an area representing liquid repellency for the liquid and a lyophilic area that is independently formed in an island shape within the liquid repellent area and is an area representing lyophillicity stronger than that of the liquid repellent area for the liquid.

What is claimed is: 
     
         1 . A molding method comprising:
 dividing a three-dimensional object as a molding target into a plurality of cross-section elements and drawing the cross-section elements as cross-section patterns on a drawing surface of a drawing stand having the drawing surface with a liquid whose curing is precipitated by receiving activation energy; and   applying the activation energy to the liquid configuring the cross-section patterns on the drawing stand   wherein, in the dividing of a three-dimensional object and the drawing of the cross-section elements, the cross-section patterns are drawn on the drawing surface that has a liquid repellent area that is an area representing liquid repellency for the liquid and a lyophilic area that is independently formed in an island shape within the liquid repellent area and is an area representing lyophillicity stronger than that of the liquid repellent area for the liquid.   
     
     
         2 . The molding method according to  claim 1 ,
 wherein the liquid has photo curability that is a property of being precipitated to be cured by receiving irradiation of light, and   wherein, in the applying of the activation energy, the liquid is irradiated with the light.   
     
     
         3 . The molding method according to  claim 1 , wherein, in the dividing of a three-dimensional object and the drawing of the cross-section elements, the cross-section patterns are drawn on the drawing surface by ejecting the liquid to the drawing stand using an ink jet method. 
     
     
         4 . 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 that is a 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; and   an energy applying device that applies activation energy to the liquid adhering to the drawing surface;   wherein, on the drawing surface, a liquid repellent area that is an area representing liquid repellency for the liquid and a lyophilic area that is independently formed in an island shape within the liquid repellent area and is an area representing lyophillicity stronger than that of the liquid repellent area for the liquid are arranged.   
     
     
         5 . The molding apparatus according to  claim 4 ,
 wherein the liquid has photo curability that is a property of being precipitated to be cured by receiving irradiation of light, and   wherein the energy applying device irradiates the liquid with the light.   
     
     
         6 . The molding apparatus according to  claim 4 , wherein the ejection head ejects the liquid in a liquid droplet state. 
     
     
         7 . The molding apparatus according to  claim 6 ,
 wherein a plurality of the lyophilic areas is disposed within the liquid repellent area,   wherein the plurality of the lyophilic areas configures a plurality of first arrangements arranged in a first direction in the plan view, and   wherein the plurality of the first arrangements is aligned in a second direction that is a direction intersecting the first direction in the plan view.   
     
     
         8 . The molding apparatus according to  claim 6 ,
 wherein a plurality of the lyophilic areas is disposed within the liquid repellent area,   wherein the plurality of the lyophilic areas configures a plurality of first arrangements arranged in a first direction in the plan view, and   wherein the plurality of the first arrangements is aligned in a zigzag pattern in a second direction that is a direction intersecting the first direction in the plan view.   
     
     
         9 . The molding apparatus according to  claim 6 ,
 wherein a plurality of the lyophilic areas is disposed within the liquid repellent area, and   wherein the plurality of the lyophilic areas configures a spire using a Fibonacci sequence.   
     
     
         10 . The molding apparatus according to  claim 7 , wherein the lyophilic areas protrude from the liquid repellent area. 
     
     
         11 . The molding apparatus according to  claim 7 , wherein a gap size between the lyophilic areas adjacent to each other is a distance equal to or less than 1.25 times an outer diameter of the liquid droplet that is ejected from the ejection head.
