Thermal melting lamination method 3D modeling for materials and filament heat melting laminate method 3d printing equipment

【Task】 The present invention is not to devise a shaped form, without installing a special device to the 3D printer device, warp does shaped articles are obtained, further comprising a flexible, shaped article excellent in surface polishability providing heat melting laminate method material for three-dimensional modeling to be obtained. A Against the polylactic acid resin (A) 100 parts by weight of an aromatic vinyl-based monomer (b1) and the vinyl cyanide monomer (b2) and the copolymer was obtained styrenic resin (B1). 10 to 900 parts by weight and / or glass transition temperature of 20 ° C. or less of the thermoplastic resin (B2) 5 to 400 parts by weight and / or plasticizer (B3) 5 to 30 parts by weight of the thermal melting lamination method 3D modeling comprising blending it is a use material. .BACKGROUND
