In a device for manufacturing a filament three-dimensional bonded member that includes: a molten filament supply unit that discharges a molten filament group downward; a chute that includes a chute inclined plate which receives a molten filament at an end in thickness direction of the group and displaces the group in such a direction as to reduce thickness of the group; a cooling water supply unit that supplies cooling water to the plate; and a fusing formation unit that three-dimensionally entangles molten filaments and simultaneously fuses contact points, grooves are formed in an upper surface of the plate, the width of each of the grooves is 0.1 mm or more and 3.0 mm or less, the depth of each of the grooves is 0.1 mm or more and 3 mm or less and a distance between the adjacent grooves is 1 mm or more and 7 mm or less.

A method for making an object with a composite material that includes at least one polymeric material in which a material of natural origin is dispersed. The method includes the steps of extruding the polymeric material in an extrusion stage; adding the material of natural origin to the polymeric material, thereby obtaining the composite material; and pressing the composite material to obtain the object. The material of natural origin is added to the polymeric material after having cooled the polymeric material downstream of the extrusion stage.
