Beschreibung
Zusammenfassung:	A fiber-reinforced thermoplastic resin filament which is obtained by impregnating a continuous reinforcing fiber with a thermoplastic resin, and which satisfies all of the following conditions (a) to (c). The present invention provides a fiber-reinforced thermoplastic resin filament which is suitable for applications in 3D printers.(a) The volume ratio of a reinforcing fiber in a fiber-reinforced thermoplastic resin filament is 30 to 80%; and the volume ratio of a thermoplastic resin in a fiber-reinforced thermoplastic resin filament is 70 to 20%.(b) The thickness of a fiber-reinforced thermoplastic resin filament is 0.01 to 3 mm.(c) The length of a filament contained in a fiber-reinforced thermoplastic resin filament is 1 m or more.
