Support material for fused deposition modeling, and manufacturing method of fused deposition modeled structure and three-dimensional object using same

Abstract

Disclosed is a support material for a fused deposition modeling. The support material has excellent adhesion to a variety of model materials and is easily dissolved and removed by washing with water. Also, the waste liquid (PVA-based aqueous solution) generated after the washing operation may be allowed to be drained as it is, in compliance with environmental regulations. The support material comprises (A) PVA-based resin having a group containing sulfonic acid or a salt thereof and (B) biodegradable polyester. The (A) PVA-based resin having a group containing sulfonic acid or a salt thereof and (B) biodegradable polyester have a sea-island structure in which one is dispersed in the other as a matrix.
