A three-dimensional shaping device includes: a plasticizing unit configured to plasticize a material to generate a plasticized material; a stage having a deposition surface on which the plasticized material is deposited; an ejection unit that has a plurality of nozzles arranged side by side along a first axis parallel to the deposition surface of the stage, and that is configured to eject the plasticized material in a continuous linear form from the plurality of nozzles toward the deposition surface; an ejection switching unit configured to individually switch between stopping and resuming ejection of the plasticized material from the plurality of nozzles; a moving unit configured to move the ejection unit with respect to the stage along a second axis that is parallel to the deposition surface of the stage and that intersects the first axis; and a control unit configured to laminate a shaping layer formed of the plasticized material on the deposited surface of the stage by controlling the plasticizing unit, the ejection switching unit, and the moving unit.

A molten material supplying apparatus includes: a first introduction unit introducing fiber material; a melting unit melting a thermoplastic resin into a molten material; a first flow path in which the molten material and the fiber material are distributed; and a nozzle communicating with the first flow path to feed a composite of the molten material and the fiber material. The melting unit includes: a facing section in which a communication hole communicating with the first flow path is formed, the facing section having a heater, and a flat screw which has a groove at a position facing the facing section, the flat screw being rotated to melt the thermoplastic resin into the molten material and supply the molten material into the communication hole. The first introduction unit introduces the fiber material into at least one of the communication hole and the first flow path.

A liquid ejecting head includes a head main body capable of ejecting a liquid supplied from a liquid storage unit, and a supply member provided with a liquid supply passage for supplying the liquid from the liquid storage unit to the head main body. The supply member has a filter mounting member provided with the liquid supply passage, a supply body that supplies the filter mounting member with the liquid, and a filter provided between the filter mounting member and the supply body. The supply member is provided with an outer portion that fixes the filter mounting member, the supply body, and the filter and that is formed by integral molding.
