Abstract: Provided is a method for producing a modeled object easily producible and capable of effectively increasing mechanical properties in modeling using a three-dimensional printer. The method for producing a modeled object includes the steps of: preparing a resin composition containing inorganic fibers with an average fiber length of 1 ?m to 300 ?m and an average aspect ratio of 3 to 200 and a thermoplastic resin; and modeling an object using the resin composition on a fused deposition modeling-based three-dimensional printer to produce a modeled object, wherein in modeling the object on the fused deposition modeling-based three-dimensional printer, a deposition pitch is less than 0.20 mm and a road width is less than 0.20 mm.
