A shaping system for manufacturing a shaped object having unevenness due to expansion of a molding sheet including a base and a thermal expansion layer laminated onto a first main surface of the base, the shaping system comprising: a control unit comprising determination means, and generation means; a printing device; and an expansion apparatus comprising first expansion means, and second expansion means, wherein the determination means determines, based on unevenness data representing the unevenness, that a convexity having a width and a length that are each greater than or equal to a respective threshold is a first convexity, and that a convexity having at least one of a width or a length that is smaller than the respective threshold is a second convexity; the generation means generates, based on (i) positions of the first convexity and the second convexity determined by the determination means and (ii) the unevenness data, first convexity data representing the first convexity and second convexity data representing the second convexity; the printing device is configured to print, based on the first convexity data generated by the generation means, onto a second main surface of the base that is located on a side opposite to the first main surface, a thermal conversion layer for conversion of electromagnetic waves into heat; the first expansion means causes heating and expansion of at least a portion of the thermal expansion layer of the molding sheet by heat released from the thermal conversion layer by irradiating with the electromagnetic waves emitted from a lamp, the thermal conversion layer printed onto the molding sheet, and the second expansion means causes, based on the second convexity data generated by the generation means, heating and expansion of a region of the thermal expansion layer by irradiating the region of the thermal expansion layer with laser light, the region of the thermal expansion layer being smaller in size than a predetermined region of the thermal expansion layer in which the first expansion means causes expansion. a control unit comprising determination means, and generation means; a printing device; and an expansion apparatus comprising first expansion means, and second expansion means, wherein the determination means determines, based on unevenness data representing the unevenness, that a convexity having a width and a length that are each greater than or equal to a respective threshold is a first convexity, and that a convexity having at least one of a width or a length that is smaller than the respective threshold is a second convexity; the generation means generates, based on (i) positions of the first convexity and the second convexity determined by the determination means and (ii) the unevenness data, first convexity data representing the first convexity and second convexity data representing the second convexity; the printing device is configured to print, based on the first convexity data generated by the generation means, onto a second main surface of the base that is located on a side opposite to the first main surface, a thermal conversion layer for conversion of electromagnetic waves into heat; the first expansion means causes heating and expansion of at least a portion of the thermal expansion layer of the molding sheet by heat released from the thermal conversion layer by irradiating with the electromagnetic waves emitted from a lamp, the thermal conversion layer printed onto the molding sheet, and the second expansion means causes, based on the second convexity data generated by the generation means, heating and expansion of a region of the thermal expansion layer by irradiating the region of the thermal expansion layer with laser light, the region of the thermal expansion layer being smaller in size than a predetermined region of the thermal expansion layer in which the first expansion means causes expansion.
