Abstract
Official abstract text for this publication.
Provided is a liquid material for forming a three-dimensional object, the liquid material adapted to be delivered to a powder material for forming a three-dimensional object to harden the powder material, the powder material containing an organic material and a base material, the liquid material including a cross-linking agent cross-linkable with the organic material and a resin having a glass transition temperature of 50° C. or higher or a melting point of 50° C. or higher.
First claim
Opening claim text (preview).
What is claimed is: 1. A three-dimensional object producing method comprising: forming a layer of a powder material for forming a three-dimensional object, where the powder material comprises an organic material and a base material; and delivering a liquid material for forming a three-dimensional object to a predetermined region of the layer of the powder material formed in the forming, wherein the three-dimensional object producing method repeats the forming and the delivering to produce a three-dimensional object, and wherein the liquid material for forming a three-dimensional object is a liquid material adapted to be delivered to a powder material for forming a three-dimensional object to harden the powder material, where the powder material comprises an organic material and a base material, where the liquid material comprises: a cross-linking agent cross-linkable with the organic material; and a resin having a glass transition temperature of 50° C. or higher or a melting point of 50° C. or higher. 2. The three-dimensional object producing method according to claim 1 , further comprising sintering the three-dimensional object produced by repeating the forming and the delivering. 3. The three-dimensional object producing method according to claim 1 , wherein the liquid material for forming a three-dimensional object is delivered according to an inkjet method. 4. The three-dimensional object producing method according to claim 1 , wherein the resin is water-soluble. 5. The three-dimensional object producing method according to claim 1 , wherein the resin comprises polyvinyl pyrrolidone. 6. The three-dimensional object producing method according to claim 1 , wherein the liquid material has a viscosity of 25 mPa·s or lower at 25° C. 7. The three-dimensional object producing method according to claim 1 , wherein the liquid material is alkaline. 8. The three-dimensional object producing method according to claim 1 , wherein the base material is coated with the organic material. 9. The three-dimensional object producing method according to claim 1 , wherein the cross-linking agent comprises any one of a water-soluble cross-linking agent and a metal salt.
