Disclosed is a composition for a three-dimensional printer filament capable of satisfying requirements as a 3D printing material requiring a soft feel of a low hardness, and a filament for a three-dimensional printer manufactured using the composition. The present invention relates to a composition for a three-dimensional printer filament, which comprises atactic polypropylene having a weight average molecular weight of 50,000 to 1,000,000, a density of 0.8 to 0.9 g / ml and a degree of stereochemistry (isotacticity, pentad II, mmmm) Wherein the polymer base has a melt index (210 DEG C, 2.16 kg) of 0.5 to 30 g / 10 min, and a composition for a three-dimensional printer filament Lt; / RTI > |
