Abstract: Provided is a composite laminate having excellent releasability from a mold during a production process, excellent surface appearance (surface smoothness) and mechano-physical properties, and excellent workability and coating adhesion. A composite laminate 1 includes an A layer 2 and a B layer 3, wherein the A layer 2 is provided directly or indirectly on one or both sides of the B layer 3, the A layer 2 contains reinforcing fibers (a1) with an average fiber length of 1 μm to 300 μm, spherical particles (a11) with a volume mean particle diameter of 0.01 μm to 100 μm, and a thermoplastic resin (a2), and the B layer 3 contains reinforcing fibers (b1) with an average fiber length of 1 mm or more and a thermoplastic resin (b2).

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 μm to 300 μm 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.
