Abstract: A resin material plasticizing device is equipped with a heating block in which a passage hole is formed to which there is supplied an elongate solid coating material, and which is capable of raising the temperature of an inner wall surface of the passage hole. At an upstream portion of the passage hole, so that an inner wall surface thereof is kept in contact with a side surface of the solid coating material, a cross section thereof which is perpendicular to an axial direction has a shape corresponding to the cross-sectional shape of the solid coating material. At least a part of the midstream portion is set in a manner so that a ratio of a circumferential length with respect to a cross-sectional area of a cross section perpendicular to the axial direction is greater than the same ratio of the upstream portion.

Abstract: A three-dimensional printing method includes a filament forming step, and a laminating step in order to laminate filaments possessing thermoplasticity and thereby obtain a three-dimensional modeled object. In the filament forming step, a coating material made of a thermoplastic resin, which is plasticized by heating, is adhered to at least a part of an outer circumferential surface of a core material, which is made of a thermoplastic resin having a lower temperature than that of the plasticized coating material, thereby obtaining the filaments. In the laminating step, the filaments, which are made up from the plasticized coating material, and the core material that is plastically deformable but at a lower temperature than the plasticized coating material, are laminated while being pressed with respect to a portion to be laminated.

Abstract: In a molding machine, an electrical current is caused to flow to a coil by a high-frequency power supply, and a magnetic field is generated, whereupon lines of magnetic force are generated so as to substantially conform to cavity faces of the stationary mold and the moveable mold. The magnetic field strength is constant with respect to position in the lengthwise direction of the coil, and eddy currents are generated uniformly with respect to the cavity faces. Because the molds have electrical resistance, Joule heat is generated by the eddy currents and electrical resistance, and the cavity faces are heated. When a material in a molten state is injected into the cavities of the heated molds, flowability of the material is promoted, and therefore the quality of the molded article is improved.

Abstract: In a molding surface-heating apparatus, eddy current is generated in a mold by an electromagnetic induction, and a molding surface of the mold is heated by the eddy current. The molding surface-heating apparatus is provided with a conductive member and a coil. The conductive member is electrically connected to and disconnected from a surface of the mold. The coil supplies a magnetic flux to the conductive member and the mold such that the magnetic flux generates the eddy current that crosses the conductive member and the mold and the eddy current passes through the molding surface.
