[Problem] To provide a material for fused-deposition-type three-dimensional modeling whereby a warp-free modeled object is obtained without devising a modeling shape and without installing a special apparatus as a 3D printer device, and whereby a modeled article having flexibility as well as excellent surface polishing properties is obtained. [Solution] A material for fused-deposition-type three-dimensional modeling, obtained by blending 10-900 parts by weight of a styrene-based resin (B1) obtained by copolymerization of an aromatic vinyl-monomer (b1) and a cyanated vinyl-monomer (b2), and/or 5-400 parts by weight of a thermoplastic resin (B2) having a glass transition temperature of 20° C. or lower and/or 5-30 parts by weight of a plasticizer (B3), with respect to 100 parts by weight of a polylactic resin (A).
[问题] 提供一种用于熔融沉积型三维建模的材料,通过该材料可以获得无翘曲的建模物体,无需设计建模形状,也无需安装特殊设备作为3D打印机设备,同时可以获得具有柔韧性和优异表面抛光性的建模物品。
