[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&#xb0; 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).

Material for fused deposition modeling type three-dimensional modeling, and filament for fused deposition modeling type 3D printing device

A natural rubber-containing thermoplastic resin composition includes a graft copolymer (A) obtained by graft-polymerizing a vinyl monomer mixture (a) including at least an aromatic vinyl monomer to a rubbery polymer (R) composed of 10 to 70% by mass of a natural rubber having a weight average particle size of 0.3 to 1.2 &#x3bc;m and 30 to 90% by mass of a synthetic rubber having a weight-average particle size of 0.2 to 0.4 &#x3bc;m, wherein particles of the natural rubber include not less than 5% by mass of natural rubber articles with a size of 1.0 &#x3bc;m or larger; and particles of the rubbery polymer (R) with a size of 1.0 &#x3bc;m or larger have an internal graft ratio of 20% or higher.

Natural rubber-containing thermoplastic resin composition and molded article thereof

The present invention relates to a thermoplastic resin composition obtained by compounding phosphoric acid and/or monosodium phosphate (D) with a resin composition including a styrenebased resin (A), a graft copolymer (B), and an aliphatic polyester resin (C), wherein the thermoplastic resin composition is excellent in mechanical properties (e.g., impact resistance) and thermal stability, and, in addition, can be molded without any problem in terms of safety and hygiene.
