1. A repairing method for a shaped object for repairing a shaped object shaped by a shaping device, the repairing method comprising:
preparing a defective portion part which is a member to be attached to a defective area in a repair target shaped object which is the shaped object where a damage in which one part is defected has occurred;
creating an attachment member which is a member to be attached to at least one part of surfaces of the repair target shaped object and the defective portion part; and
attaching the attachment member so as to cover at least one part of a boundary portion between the repair target shaped object and the defective portion part in a state where the repair target shaped object and the defective portion part are brought into contact with each other; wherein
at least one part of a surface of the repair target shaped object is colored;
in the step of attaching the attachment member, the attachment member including an adhesive layer and a colored layer is created using a shaping device capable of shaping the shaped object colored by a layered shaping method, wherein the adhesive layer is a layer for adhering the attachment member to the repair target shaped object and the defective portion part, and the colored layer is a layer colored and formed according to a color of a portion of the shaped object to be covered by the attachment member;
the repair target shaped object includes:
a region to be colored subjected to coloring at a surface of the repair target shaped object; and
a light reflecting region formed on an inner side of the region to be colored in a light reflecting manner;
the shaping device used in the step of attaching the attachment member is a device that ejects an ultraviolet-curable material as a shaping material, and includes:
a plurality of ejection heads each of which ejects the shaping material, and
an ultraviolet light source that irradiates the ejected shaping material with ultraviolet light;
the plurality of ejection heads include at least:
a coloring material head that ejects a color material which is a colored shaping material for coloring; and
a light reflective material head that ejects a light reflective material which is a shaping material having light reflectivity:
in the step of attaching the attachment member,
the colored layer is formed using at least the color material ejected from the coloring material head, the adhesive layer is formed using the shaping material ejected from any one of the plurality of ejection heads, and at a time of forming the adhesive layer;
the shaping material is irradiated with ultraviolet light from the ultraviolet light source to increase viscosity of the shaping material to a state having adhesiveness; and
after attaching the attachment member to the repair target shaped object, the attachment member is irradiated with ultraviolet light to cure the shaping material in the adhesive layer.
