<P>PROBLEM TO BE SOLVED: To avoid a state in which a resin is scraped off due to the contact between a roller part and a cured resin. <P>SOLUTION: A three-dimensional shaping apparatus includes: a roller part 25 that presses a flowable model material MA or a flowable supporting material SA from the upper surface and scrapes off a surplus amount of the model material MA or the supporting material SA; a curing means 24 for curing the model material MA and the supporting material SA; a head part 20 that includes a shaping-material ejection means, the roller part 25, and the curing means 24; a horizontal driving means that allows the head part 20 to perform a reciprocating scanning in the horizontal direction; a vertical driving means that moves the relative position in the height direction between the head part 20 and a shaping plate 40; and a control means 10 that controls the driving of the horizontal driving means and the vertical driving means, and also, controls the ejection of the shaping material by the shaping-material ejection means and the curing by the curing means 24. The width of the roller part 25 is formed narrower than the width of a model-material ejection nozzle 21, provided in the shaping-material ejection means, and the width of a supporting-material ejection nozzle 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
