Abstract
An apparatus and a method for forming a three-dimensional article with photosetting or thermosetting 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 head to a stage and laminated thereon. The laminated material is exposed to light by a light source to be 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.
