Abstract
Provided is the method for manufacturing a three-dimensional structure with a less amount of internal voids or bubbles, and also to provide a 3D printer filament used for manufacturing such three-dimensional structure. The method for manufacturing a three-dimensional structure, the method comprises melting and depositing a filament using a 3D printer, the filament comprising a commingled yarn that contains a continuous reinforcing fiber (A) and a continuous thermoplastic resin fiber (B), with a dispersity of the continuous reinforcing fiber (A) in the commingled yarn of 60 to 100%.
