Abstract

A molded resin strand includes a first layer containing thermoplastic resin, and a second layer covering the first layer and containing thermoplastic resin exhibiting physical properties different from those of the first layer. For example, the second layer is melt-extruded with the second layer covering the first layer. A three-dimensional object is modeled by lamination deposition by fusion between adjacent second layers. In a molded resin strand manufacturing method, a melt-kneaded resin material is continuously extruded from a ferrule of an extruder. The extruded molded resin strand is vacuum-sucked while passing through a sizing device. Subsequently, the molded resin strand is wound up after cooling solidification. The sizing device is provided with a space having a circular cross section, and a surface of the sizing device facing the space is provided with a plurality of vacuum suction grooves.
