[Problem] To provide a program, for example, with which it is possible to further improve the accuracy of the shape of a three-dimensional fabricated object fabricated by means of a 3D printer for construction than before. [Solution] According to one embodiment of the present invention, a program for use in a 3D printer for construction is provided, the program being configured to cause a computer to perform an acquisition step, a division step, and a generation step. In the acquisition step, three-dimensional shape data indicating a target shape of a three-dimensional fabricated object to be fabricated by means of the 3D printer for construction is acquired. In the division step, some or all of the three-dimensional shape data is divided into a plurality of pieces of slice data. The slice data is data that has an arbitrary thickness along a fabrication direction of the three-dimensional fabricated object. The slice data has a contour corresponding to the outer surface of the three-dimensional fabricated object. In the generation step, a tool path which is a movement path for a nozzle used in the 3D printer for construction is generated. The process of generating the tool path includes adjustment processing in which the target shape of the three-dimensional fabricated object is adjusted on the basis of the slice data.
