Abstract: PROBLEM TO BE SOLVED: To accurately and rapidly form a support structure together with a three-dimensional article in an apparatus for manufacturing the three- dimensional article by laminating a fluidized material having a higher curing temperature than an ambient temperature on each layer for constituting a section of the three-dimensional article. SOLUTION: A high-speed trially forming apparatus of the three-dimensional article with the support structure supplies the fluidized material having the higher curing temperature than the ambient temperature to be discharged from a print head 9 to each layer for constituting the three-dimensional article on a material supply base 18, and accurately decides a thickness of the layer by a smoothing member 11 having a rotary cylinder 18a. The layer for constituting the section is formed of data of the three-dimensional article and data of the support structure, and the article and the structure are simultaneously laminated in a vertical direction at the same speed.
