摘要： An object of the invention is to provide a filament for a material extrusion-type three-dimensional printer, which filament contains an aromatic polyester resin, and which overcomes the shortcomings of a filament for a material extrusion-type three-dimensional printer that is composed of an ABS resin. Provided is a filament for a material extrusion-type three-dimensional printer, the filament including an aromatic polyester resin containing 50 mol % or more of aromatic dicarboxylic acid units, and 3 mol % or more of isophthalic acid units, with respect to the total amount of dicarboxylic acid units. The aromatic polyester resin preferably has a melt flow rate (230° C., 2.16 kgf) of 7 g/10 min or more, and an intrinsic viscosity of 0.80 dL/g or less.

摘要： The present invention provides a filament for material extrusion 3D printer molding, which affords a molded article having soft texture and excellent heat resistance and among others, exhibits good moldability in molding by a material extrusion 3D printer. The present invention relates to a filament for material extrusion 3D printer molding, including a thermoplastic elastomer which contains at least a specific block copolymer and in which the ratio between storage modulus and loss modulus measured at 200° C. and 100 Hz by dynamic viscoelasticity measurement is in a specific range.
