MATERIAL FOR FUSED-DEPOSITION-TYPE THREE-DIMENSIONAL MODELING, AND FILAMENT FOR FUSED-DEPOSITION-TYPE 3D PRINTING DEVICE

摘要

[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).
