PROBLEM TO BE SOLVED: To improve the vector exposure efficiency by forming a material layer which comes into contact with either one of material layers formed right before, and repeating an exposure work conforming to a plurality of exposure vectors a plurality of times, and providing a plurality of non-exposure vectors between a plurality of continuous specified exposure vectors. SOLUTION: A beam source which emits a specified curing stimulation beam is installed. As a preparation to form a next curing layer of a molded article, a new material layer which comes into contact with a material layer formed right before, is formed. Then, a curable material is exposed to the specified curing stimulation beam conforming to a plurality of exposure vectors expressing the next curing layer of the molded article, and the next curable layer is formed. Then, the curable layer forming motion and the exposure motion are repeated a plurality of times, and the article comprising a plurality of closely joined curable layers is molded. In this case, at least between a plurality of areas from among the continuous two exposure vectors, a plurality of non-exposure vectors are fed. The non-exposure vectors include a gradient vector and a jump vector. |
