Abstract: In a device for manufacturing a filament three-dimensional bonded member includes: a molten filament supply device which supplies a plurality of molten filaments; a three-dimensional structure formation device which receives and then cools and solidifies the molten filaments so as to form a filament three-dimensional bonded member; and a controller which controls the molten filament supply device and the three-dimensional structure formation device, a hardness index measurement device is provided which measures the hardness index of the filament three-dimensional bonded member that is brought into a cooled state by the three-dimensional structure formation device, and the controller uses the information of the measurement of the hardness index measurement device that is fed back and thereby performs feedback control on at least one of the molten filament supply device and the three-dimensional structure formation device so as to reduce a variation in the hardness of the formed filament three-dimensional bonded member.

Abstract: A manufacturing apparatus and manufacturing method for manufacturing a three-dimensional filaments-linked structure includes: divided weight information acquisition means which records divided weight information acquired by dividing weight distribution in a height direction of a person in a height axis direction, in correlation with a distance from a top of a head of the person; and three-dimensional linked structure formation means which tangles and fuses filaments of a thermoplastic resin material extruded from an extruder in a three-dimensional net shape, and forms a three-dimensional filaments-linked structure which is long in a product streaming direction, and the three-dimensional linked structure formation means includes filament density control means which controls filament density in the product streaming direction based on the divided weight information. As a result of the configuration, it is possible to promptly, reliably, and efficiently manufacture products with desired specifications for customers who request products with made-to-order specifications.
