Abstract
An apparatus and a method for forming a three-dimensional article with two-part curable material on the basis of a three-dimensional information on the article by means of an ink jet method. The material is jetted from at least one ink jet to a stage and laminated thereon. In two-part curable material, microcapsules which encapsulate setting material of the two-part curable material are scattered. These microcapsules are ruptured by radiation of light and so on. The laminated two-part material is supplied with radiation of light from a light source so that it is cured. In this process, a jetting direction of the material from the ink jet head to the stage and/or a jetting amount of the material jetted from the ink jet head is changed in accordance with the information by a control unit, thereby forming a solid article having a desired three-dimensional shape.
