Abstract
Provided is a liquid material for forming a three-dimensional object used for forming a three-dimensional object made of a powder material for forming a three-dimensional object containing an organic material and a base material, wherein the liquid material contains a cross-linking agent cross-linkable with the organic material and a water-soluble resin having a weight average molecular weight of greater than or equal to 50,000.
Claims15
A liquid consisting of:
- a solvent;
- a cross-linking agent which comprises a metal salt;
- a water-soluble resin having a weight average molecular weight of greater than or equal to 50,000;
- optionally, a stabilizing agent which is at least one selected from the group consisting of a compound that comprises an amino group, a compound that comprises a phosphono group, a gluconic acid, and a salt of the gluconic acid;
- and
- optionally, at least one selected from the group consisting of a surfactant, a defoamer, a pH adjustor, an antiseptic/fungicide, a chelate agent, and an anti-rust agent,
- wherein the liquid is used for forming a three-dimensional object made of a powder that comprises an organic material and a base material,
- wherein the liquid is capable of dissolving the organic material, and
- wherein the cross-linking agent is cross-linkable with the organic material.
