soluble material for three-dimensional modeling, method for making a three-dimensional object by a fused deposition modeling system, and use of thermoplastic resin

摘要

the present invention is a soluble material for three-dimensional modeling which is used as a support material material to support a three-dimensional object when the three-dimensional object is manufactured by a 3d printer of a fused deposition modeling system and which contains a thermoplastic resin having a hydrophilic group and an organic salt compound represented by a general formula (i) below: (r1-so3-) nxn + (i). according to the present invention, it is possible to provide a soluble material for three-dimensional modeling which is used for a support material and which is capable of suppressing the degradation of the modeling precision of a three-dimensional object when the three-dimensional object is manufactured by a 3d printer with a fused deposition modeling system, and has a high dissolution rate for neutral water to be quickly removed from a three-dimensional object precursor without the use of a strong alkaline aqueous solution
