Title:
SOLUBLE MATERIAL FOR THREE-DIMENSIONAL MODELING
Document Type and Number:
WIPO Patent Application WO/2019/065824
Kind Code:
A1
Abstract:
This soluble material for three-dimensional modeling is used as a material for a support member that supports a three-dimensional model when the three-dimensional model is produced by an FDM 3D printer. This soluble material for three-dimensional modeling contains a copolymer α which has a vinyl monomer unit A that has a hydrophilic group and a vinyl monomer unit B other than the vinyl monomer unit A, said vinyl monomer unit B having a group which is interactive with the hydrophilic group. This soluble material for three-dimensional modeling is capable of suppressing accuracy deterioration of a three-dimensional model by suppressing foaming even if used in the production of a three-dimensional model by an FDM method, in which a material having high heat resistance is used as a modeling material, after being exposed to high humidities; and this soluble material for three-dimensional modeling has a high rate of dissolution in neutral water and is able to provide a method for producing a three-dimensional model, wherein a support member is quickly removed from a three-dimensional model precursor without using a strong alkaline aqueous solution.
