Abstract

A method of manufacturing a three-dimensional object includes imparting a first liquid having a first composition including a solvent and a curable material and a second liquid having a second composition to form a liquid film, curing the liquid film, and repeating the imparting and the curing to obtain the three-dimensional object, wherein the imparting position and the imparting amount of each of the first liquid and the second liquid are controlled in such a manner that the liquid film includes multiple areas where at least one of post-curing compression stress and post-curing modulus of elasticity is different.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of manufacturing a three-dimensional object comprising:
 imparting a first liquid having a first composition including a solvent and a curable material and a second liquid having a second composition to form a liquid film;   curing the liquid film; and   repeating the imparting and the curing to obtain the three-dimensional object,   wherein an imparting position and an imparting amount of each of the first liquid and the second liquid are controlled in such a manner that the liquid film includes multiple areas where at least one of post-curing compression stress and post-curing modulus of elasticity is different.   
     
     
         2 . The method according to  claim 1 , wherein the imparting position of the first liquid matches the imparting position of the second liquid. 
     
     
         3 . The method according to  claim 1 , wherein the imparting is conducted utilizing a liquid discharging method. 
     
     
         4 . The method according to  claim 1 , wherein the imparting amount of the first liquid and the imparting amount of the second liquid are controlled based on a volume of a droplet or a number of droplets to be imparted. 
     
     
         5 . The method according to  claim 1 , wherein the second liquid includes no curable material. 
     
     
         6 . The method according to  claim 1 , wherein the imparting position and the imparting amount of each of the first liquid and the second liquid are controlled to further form a support structure to support the three-dimensional object. 
     
     
         7 . A liquid set for manufacturing a three-dimensional object comprising:
 a first liquid having a first composition including a solvent and a curable material; and   a second liquid having a second composition.   
     
     
         8 . The liquid set according to  claim 7 , wherein the solvent includes water, the curable material includes a polymerizable monomer, and the first liquid further includes a mineral. 
     
     
         9 . The liquid set according to  claim 7 , wherein the second liquid includes at least one of a cross-linking agent and a mineral. 
     
     
         10 . The liquid set according to  claim 7 , wherein at least one of the first liquid and the second liquid includes a polymerization initiator. 
     
     
         11 . The liquid set according to  claim 7 , wherein the second liquid includes a different polymerizable monomer from the polymerizable monomer included in the first liquid. 
     
     
         12 . The liquid set according to  claim 7 , wherein the second liquid includes a same polymerizable monomer as the polymerizable monomer included in the first liquid. 
     
     
         13 . The liquid set according to  claim 7 , wherein the second liquid includes no curable material. 
     
     
         14 . The liquid set according to  claim 7 , further comprising a third liquid having a third composition. 
     
     
         15 . A method of manufacturing a three-dimensional object comprising:
 imparting the first liquid and the second liquid of the liquid set of  claim 7  to form a liquid film; and   curing the liquid film.   
     
     
         16 . A device for manufacturing a three-dimensional object comprising:
 an imparting device to impart the first liquid and the second liquid of the liquid set of  claim 7  to form a liquid film; and   a curing device to cure the liquid film.   
     
     
         17 . The device according to  claim 16 , wherein the curing device includes an ultraviolet light-emitting diode. 
     
     
         18 . The device according to  claim 16 , further comprising a smoothing device to smooth the liquid film cured. 
     
     
         19 . A gel object comprising:
 a solvent; and   a polymer,   wherein at least one of 80 percent compressive stress-strain and modulus of elasticity has a continuous gradient.   
     
     
         20 . The gel object according to  claim 19 , wherein 80 percent compressive stress-strain is 10-10,000 kPa.
