Abstract: A three-dimensional molding method in which both a support material 2 and a test piece 3 are separately joined to partial regions of a part to be produced 1, which is molded by dispersion of a powder by traveling of a squeegee and sintering of the powder by irradiation of a laser beam or an electron beam, or the test piece 3 is separately joined to a plurality of the support materials 2, or the test piece 3 is joined to a partial region of the part to be produced 1 to mold the support material 2 and the test pieces 3 in the same step.

Abstract: A three-dimensional shaping method in which the powder supplying blade 2 is able to travel without any problems, in which a control system stores in advance a fine sintered region 11 so that any one of a cross-sectional area or a mean diameter in the horizontal direction, a shaping width and an undercut angle at the end is equal to or less than a predetermined extent, or the control system makes a determination in a sintering step, for said each element, so in the case of the raised sintered portions 12 forming on the upper side of the sintered region 11, a rotating cutting tool 3 cuts the raised sintered portions 12 entirely or partially, thereby achieving the object.

Abstract: The purpose of the present invention is to provide a rotary atomizing head that paint supplied to an inner peripheral surface is spread on the inner peripheral surface uniformly so as to improve the quality of coating and to lengthen the life of the rotary atomizing head. An inner peripheral surface 67 diametrically expanded from the center of the rotary atomizing head to a peripheral edge 61b is formed and centrifugal force generated by the rotation is applied on the paint supplied to the inner peripheral surface 67 so as to discharge the paint outside atomizingly. A step part 68 is formed at the middle portion of the inner peripheral surface 67 between paint supply holes 65d, supplying paint or solvent to the inner peripheral surface 67, and the peripheral edge 61b of the inner peripheral surface 67.

Abstract: This station (10) comprises at least two areas (11, 12) for cleaning/filling a reservoir, each adapted to receive a sub-assembly (7) formed by a reservoir (8) and a sprayer (9) while this sub-assembly (7) is disconnected from the robot. A device or devices (51, 52) for cleaning and/or filling the reservoir and/or the sprayer in each of these areas are provided, while these areas (11, 12) are adapted to be brought (F2, F3) into a position of connection of a sub-assembly (7), disposed in one (11) of them with the cleaning and/or filling device or devices (51, 52). The process consists, inter alia, in positioning (F6) a coating product supply unit (52), in a position of connection with the first sub-assembly (7) received in an area (11) of the station (10) of cleaning/filling.
