Zusammenfassung:	Provided is a composition for three-dimensional printing capable of producing a three-dimensionally printed article having excellent mechanical strength, as well as excellent flexibility and excellent toughness. The composition for three-dimensional printing contains an aromatic polyetherketone resin (I) and a fluorine-containing copolymer (II). The composition satisfies a ratio r2/r1 of 1.60 or lower, wherein r1 represents an average dispersed particle size of the fluorine-containing copolymer (II) and r2 represents an average dispersed particle size of the fluorine-containing copolymer (II) after melt flow rate measurement at 380°C and a load of 5000 g with 5-minute pre-heating in conformity with ASTM D1238.
