  • Patent number: 11718732
    Abstract: Provided is a resin composition, a filament and resin powder for a three-dimensional printer, a shaped object, and a production method for the shaped object, all of which make it easy to produce a shaped object and can improve, in shaping using a three-dimensional printer, the resistance to delamination of the shaped object and the resistance to warpage and shrinkage of the shaped object. A resin composition contains: inorganic fibers having an average fiber length of 1 ?m to 300 ?m and an average aspect ratio of 3 to 200; and a thermoplastic resin and serves as a shaping material for a three-dimensional printer.

  • Publication number: 20230173745
    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.
