Abstract

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.
