The invention discloses a three-dimensional modeling method and a three-dimensional modeling device. In a three-dimensional molding method and a three-dimensional molding device (10), a molding path (66) for each of a plurality of layers includes an inner molding path (68) and an outer molding path (70) for molding an inner wall portion (42) and an outer wall portion (44) that surround a space (16) and are adjacent in the inside-outside direction. The advancing directions of the inner molding path (68) and the outer molding path (70) face the same direction. Therefore, the mechanical strength of the three-dimensional modeling object can be improved. In addition, deformation of a shape such as warping of the three-dimensional shaped object can be suppressed. 本发明公开一种三维造型方法和三维造型装置。在三维造型方法和三维造型装置(10)中，多个层中的每一层的造型路径(66)包括用于造型包围空间(16)，且沿着内外方向相邻的内侧壁部(42)和外侧壁部(44)的内侧造型路径(68)和外侧造型路径(70)。内侧造型路径(68)和外侧造型路径(70)的行进方向朝向同一方向。据此，能够提高立体造型物的机械强度。另外，能够抑制立体造型物的翘曲等形状的变形。
