When a filament does not have sufficient impact strength, the filament breaks during modeling, and the model itself is vulnerable to impact and easily breaks. ADVANTAGE OF THE INVENTION According to this invention, a molded article can be manufactured favorably and the filament for 3D printers which is excellent in impact resistance can be obtained. A filament for a 3D printer comprising a biodegradable thermoplastic resin (A) and a rubbery graft polymer (B) obtained by graft polymerization of a vinyl monomer to a rubbery polymer.
