     First Embodiment 
       FIG.  1    is a schematic diagram illustrating a configuration of a three-dimensional modeling apparatus  10  according to a first embodiment. A three-dimensional modeling apparatus  10  according to the embodiment includes a container  110 , a carrier  120 , and a blower unit  160 . The container  110  accommodates a curable composition  20 . The carrier  120  is configured to face an inner surface  113  of the container  110  and to have a variable distance with respect to the inner surface  113 . The blower unit  160  performs blowing between the carrier  120  and the container  110 . Further, in a case where the curable composition  20  is cured in the container  110 , a modeled object  200  and a support portion  210 , which connects the carrier  120  to the modeled object  200 , are formed. A wind  165  from the blower unit  160  is at least temporarily output toward at least one of the modeled object  200  and the support portion  210 . Description will be performed in detail below. 
     The three-dimensional modeling apparatus  10  is an apparatus that forms the modeled object  200  by curing the curable composition  20  based on three-dimensional data indicating a shape of the modeled object  200 . The modeled object  200  is not particularly limited and may be at least one of a dental object and a medical object. In modeling of the dental object and the medical object, it is necessary to precisely model shapes according to individual users. Therefore, the use of the three-dimensional modeling apparatus  10  is suitable for modeling the dental object or the medical object. 
     In the three-dimensional modeling apparatus, there is a case where temperature rise occurs at a reaction portion and a vicinity thereof due to a reaction heat generated by curing the curable composition. If so, a cured substance of the curable composition is easily attached to the container, and the modeled object is warped or deformed. Therefore, it is necessary to suppress the temperature rise by releasing the reaction heat. On the other hand, cooling of the whole curable composition in the container leads to reduction in a formation speed of the modeled object  200 . 
     In the three-dimensional modeling apparatus  10  according to the embodiment, the wind  165  from the blower unit  160  is at least temporarily output toward at least one of the modeled object  200  and the support portion  210 . In this manner, it is possible to effectively release heat of the reaction portion via the modeled object  200  or via the modeled object  200  and the support portion  210  while suppressing a decrease in a temperature of the curable composition  20 . 
     In addition, in the embodiment, when the wind  165  from the blower unit  160  is at least temporarily output toward at least the support portion  210 , a guide portion, which changes an orientation of the wind  165  from the blower unit  160  to a direction toward the modeled object  200 , is formed between the carrier  120  and the modeled object  200 . In this manner, it is possible to reliably cool the modeled object  200  while further reducing a possibility that the wind  165  applies to the curable composition  20 . 
     Hereinafter, an example, in which the wind  165  from the blower unit  160  is output toward the support portion  210  and the guide portion is formed between the carrier  120  and the modeled object  200 , will be described. However, the present invention is not limited to the example, and the wind  165  from the blower unit  160  may be directly output toward the modeled object  200 . 
     In addition, hereinafter, an example, in which the curable composition  20  is photocurable and the three-dimensional modeling apparatus  10  models the modeled object  200  through the light irradiation, will be described. However, a type of the three-dimensional modeling apparatus  10  is not limited to the example. 
     The curable composition  20  is, for example, a resin composition having fluidity, and includes one or more selected from the group consisting of an acrylic resin, a methacrylic resin, a styrene resin, an epoxy resin, a urethane resin, an acrylate resin, an epoxy acrylate hybrid resin, an epoxy oxetane acrylate hybrid resin, a urethane acrylate resin, a methacrylate resin, a urethane methacrylate resin, and monomers of the resins. In addition, the curable composition  20  may include a polymerization initiator, a filler, a pigment, a dye and the like. 
     In the embodiment, the curable composition  20  is photocurable, and the container  110  has at least a part provided with a light transmission portion  112 . The three-dimensional modeling apparatus  10  according to the embodiment further includes an irradiation unit  130  and a control unit  140 . The irradiation unit  130  irradiates the curable composition  20  between the carrier  120  and the light transmission portion  112  with light via the light transmission portion  112 . The control unit  140  controls a position of the carrier  120  and the irradiation unit  130 . Here, the control unit  140  controls the position of the carrier  120  and the irradiation unit  130  so that the guide portion is formed. Each component of the three-dimensional modeling apparatus  10  will be described in detail below. 
     The container  110  of the three-dimensional modeling apparatus  10  accommodates the curable composition  20 . Apart of the container  110  is provided with the light transmission portion  112  having a higher light transmissivity than other parts. The light transmission portion  112  is, for example, glass. The inner surface  113  is a part of the inner surface of the container  110 , and, specifically, the inner surface  113  is a surface, which is on an inner side of the container  110 , of the surface of the light transmission portion  112 . In the light transmission portion  112 , light irradiated from an outside of the container  110  is transmitted to an inside of the container  110  with high efficiency. As a result, the curable composition  20  in a vicinity of the inner surface  113  is cured. In the example of the drawing, the container  110  has a bat shape. Further, the light transmission portion  112  is provided at a bottom of the container  110 . In addition, an introduction hole  115  for introducing the curable composition  20  is provided at a side surface of the container  110 . 
     The carrier  120  is a member that becomes a base for modeling. A surface  122  of the carrier  120  faces the inner surface  113  of the light transmission portion  112  in parallel. The three-dimensional modeling apparatus  10  according to the embodiment further includes a driving unit  142  that drives the carrier  120  at least in a direction which is perpendicular to the inner surface  113 . In a case where the carrier  120  is driven, a distance between the surface  122  and the inner surface  113  changes. 
     In the modeling of the modeled object  200 , the support portion  210 , and the guide portion, the curable composition  20  cured in the vicinity of the inner surface  113  is laminated on the surface  122  of the carrier  120 . Further, a three-dimensional structure is formed on the surface  122  by repeatedly curing and laminating the curable composition  20  while widening the distance between the surface  122  and the inner surface  113 . Note that, in the drawing, the modeled object  200  illustrates a structure in the middle of the modeling. 
     The carrier  120  is configured to include, for example, metal. The metal includes aluminum, stainless steel, and the like. In addition, the carrier  120  may include a surface layer. The surface layer includes, for example, an oxide layer of the above-mentioned metal, a hard coat layer obtained by curing the curable composition, a coating layer, and a resin layer. The resin layer includes PET, PP, and the like. The resin layer can be formed on the carrier  120  by attaching, for example, a film or a sheet. 
     The irradiation unit  130  is configured to include, for example, a light source and an optical drawing system. Although the light source is not particularly limited, the light source may include, for example, an ultraviolet light source, an incandescent lamp, a fluorescent lamp, a phosphorescent lamp, a laser diode, or a light emitting diode. Although the optical drawing system is not particularly limited, the optical drawing system includes at least one of, for example, a mask, a spatial light modulator, a micro mirror device, and a micro electromechanical systems (MEMS) mirror array. In addition, the irradiation unit  130  includes a light source and a driving apparatus for the optical drawing system, and performs light irradiation on the curable composition  20  under the control of the control unit  140 . The irradiation unit  130  may further include optical components such as a lens and a shutter. 
     In the irradiation unit  130 , the light transmission portion  112  is irradiated with light from the light source via the optical drawing system. When light output from the irradiation unit  130  is a light beam, a light irradiation region is scanned with the light beam, and the curable composition  20  in the scanned light irradiation region is cured. In addition, light may be simultaneously projected onto a whole or apart of the light irradiation region from the irradiation unit  130 . 
     The control unit  140  controls the irradiation unit  130  and the driving unit  142 . The three-dimensional modeling apparatus  10  further includes a storage unit  150 , and the storage unit  150  holds information indicating a three-dimensional shape of a structure to be modeled in advance. The control unit  140  reads the information indicating the three-dimensional shape from the storage unit  150 , and generates light irradiation information including information indicating a plurality of light irradiation regions. Here, each light irradiation region is a region on which the light irradiation should be performed by the irradiation unit  130 , and corresponds to a cross-sectional shape parallel to the inner surface  113  of the structure to be modeled. Further, the light irradiation information includes information indicating the plurality of light irradiation regions, together with information indicating an order of the light irradiation. Note that, the light irradiation information is not limited to be generated by the control unit  140 , and may be generated on the outside in advance and held in the storage unit  150 . 
     The control unit  140  controls the irradiation unit  130  such that the light irradiation is sequentially performed on the light irradiation regions based on the light irradiation information. In addition, the control unit  140  controls the driving unit  142  to change the distance between the surface  122  and the inner surface  113  according to a light irradiation timing of each light irradiation region. As a result, the modeled object  200 , the support portion  210 , and the guide portion are formed between the carrier  120  and the inner surface  113 . 
     Note that, the distance between the surface  122  and the inner surface  113  may change continuously or intermittently. When the distance changes intermittently, the control unit  140  widens the distance corresponding to one layer according to a switching timing of the light irradiation region. When a plurality of layers are formed in this manner, the modeled object  200 , the support portion  210 , and the guide portion are obtained as a laminated structure. The amount of change in the distance corresponding to one layer is, for example, equal to or larger than 30 μm and equal to or less than 100 μm. On the other hand, when the distance changes continuously, the control unit  140  switches the light irradiation region according to a changing speed of the distance and a curing speed of the curable composition  20 . In this manner, the modeled object  200  having a smooth surface rather than a case where the distance changes intermittently may be obtained. 
     As described above, in addition to the modeled object  200 , the support portion  210  that connects the carrier  120  and the modeled object  200  is formed between the carrier  120  and the inner surface  113 . The support portion  210  is apart that is removed from the modeled object  200  after the light irradiation is completed with respect to all the light irradiation regions. A shape of the support portion  210  is not particularly limited, and is, for example, a column shape, a wall shape, a mesh shape, or a lattice shape. The number of support portions  210  is not particularly limited and may be one or more. In addition, the modeled object  200  may have a part which is directly connected to the carrier  120 . 
     In addition, between the carrier  120  and the modeled object  200 , the guide portion that changes the orientation of the wind  165  from the blower unit  160  to the direction toward the modeled object  200  is formed. Only one guide portion may be provided or a plurality of guide portions may be provided. The guide portion will be described later in detail with reference to another drawing. 
     The blower unit  160  is, for example, a blower fan. In addition, the blower unit  160  may be configured to include a cooling apparatus for blowing a cold wind. The cooling apparatus is, for example, an apparatus that performs cooling through water cooling or with a Peltier element. The blower unit  160  outputs the wind  165  toward between the modeled object  200  and the carrier  120 . Specifically, the wind from the blower unit  160  is at least temporarily output toward the guide portion. An output direction of the wind  165  of the blower unit  160  may be fixed or may be changed during modeling. However, the blower unit  160  does not output the wind  165  toward a liquid surface of the curable composition  20 . In this manner, it is possible to suppress the decrease in the temperature of the curable composition  20 . 
       FIGS.  2 A to  2 C  are diagrams illustrating a first example of the guide portion  212 .  FIGS.  2 A to  2 C  illustrates an enlarged part of the support portion  210  where the guide portion  212  is provided.  FIG.  2 A  is a perspective diagram,  FIG.  2 B  is a diagram illustrating a state viewed from a direction perpendicular to the surface  122 , and  FIG.  2 C  is a cross-sectional diagram illustrating a cross section perpendicular to the surface  122 . It is assumed that the wind  165  blows from a left side of the drawings. 
     The guide portion  212  is configured to change the orientation of the wind  165  from the blower unit  160  to the direction toward the modeled object  200 . In the embodiment, the guide portion  212  is integrally provided with the support portion  210 . For example, the guide portion  212  may have a structure added to the support portion  210  or may be configured by deforming a part of the support portion  210 . For example, the guide portion  212  can have a structure protruding from the support portion  210  at least in a direction parallel to the inner surface  113 . In addition, one or more guide portions  212  joined to the plurality of support portions  210  may be provided. 
     The guide portion  212  has, for example, a guide surface  213  for receiving the wind  165  from the blower unit  160  and changing a direction of the wind  165  toward the modeled object  200 . The guide surface  213  maybe a flat surface or a curved surface. For example, the guide surface  213  diagonally faces the blower unit  160  and the modeled object  200 . Further, it is preferable that the guide surface  213  is visible when the guide portion  212  is viewed from a blowing direction of the blower unit  160 . Note that, the wind  165  from the blower unit  160  may be guided to the modeled object  200  via the plurality of guide portions  212 . 
     An area S G  of the guide surface  213  is not particularly limited, and is preferably equal to or larger than 1 mm 2  and is more preferably equal to or larger than 10 mm 2  in order to effectively change the orientation of the wind  165 . Note that, when a plurality of guide surfaces  213  are provided, the area S G  is the sum of areas of all the guide surfaces  213 . 
     In the example illustrated in  FIGS.  2 A to  2 C , the guide portion  212  has a blade-shaped structure joined to the support portion  210 . In the example, although the support portion  210  has a cylindrical shape, the support portion  210  is not limited to the cylindrical shape. 
     In the blade-shaped structure, the plate-shaped guide portion  212  is obliquely joined to the support portion  210  to surround a part of an outer periphery of the support portion  210 . Further, the guide surface  213  of the guide portion  212  is a surface of the guide portion  212  on a side of the modeled object  200 , and is provided obliquely with respect to the surface  122  and the inner surface  113 . More specifically, the guide portion  212  is inclined to approach the inner surface  113  as increasing distance from the support portion  210 . In this way, in a case where the guide portion  212  is added to the support portion  210 , a surface area can be increased, and thus efficiency of heat radiation via the support portion  210  can be improved. Two or more guide portions  212  may be provided with respect to one support portion  210 . 
       FIGS.  3 A to  3 C  are diagrams illustrating a second example of the guide portion  212 .  FIGS.  3 A to  3 C  illustrates an enlarged part of the support portion  210  where the guide portion  212  is provided.  FIG.  3 A  is a perspective diagram,  FIG.  3 B  is a diagram illustrating a state viewed from the direction perpendicular to the surface  122 , and  FIG.  3 C  is a cross-sectional diagram taken along a line A-A of  FIG.  3 B . It is assumed that the wind  165  blows from a left side in  FIGS.  3 A and  3 B . 
     Also in the drawing, the guide portion  212  has a blade-shaped structure joined to the support portion  210 . In the example, a height of a joining position of the plate-shaped guide portion  212  with respect to the support portion  210  changes along a circumferential direction. Specifically, the height of the joining position of the guide portion  212  with respect to the support portion  210  approaches the inner surface  113  as increasing distance from the blower unit  160 . By doing so, the guide portion  212  is inclined to approach the inner surface  113  as increasing distance from the blower unit  160 . In addition, in the example, since the support portion  210 , to which the guide portion  212  is joined, is not positioned between the guide portion  212  and the blower unit  160 , the wind  165  from the blower unit  160  is not blocked. 
       FIG.  4    is a perspective diagram illustrating a third example of the guide portion  212 . The drawing illustrates an enlarged part of the support portion  210  where the guide portion  212  is provided. In the example, the guide portion  212  is configured by deforming a part of the support portion  210 . In addition, in the example, the guide portion  212  is a tapered portion of the support portion  210 . The tapered portion becomes thinner in the direction toward the modeled object  200  from the support portion  210 . In the tapered portion, an area of a cross section parallel to the inner surface  113  of the support portion  210  becomes smaller as approaching the modeled object  200 . Specifically, the support portion  210  has a wall shape, and has a thickness reduced at the tapered portion. However, the support portion  210  is not limited to the wall shape. More specifically, in the example, a part of the surface of the support portion  210  on a side of the blower unit  160  serves as the guide surface  213 , and is included in the guide portion  212 . 
     As another example, for example, the guide portion  212  may be a ventilation hole having an opening facing the blower unit  160  and an opening facing the modeled object  200 . In addition, the support portion  210  may extend obliquely with respect to the surface  122  such that the whole support portion  210  functions as the guide portion  212 . 
     Note that, a structure of the guide portion  212  is not limited to the examples. 
     It is possible to set a specific region, to which the wind  165  is applied, of the modeled object  200  by adjusting a position where the guide portion  212  is provided, a shape of the guide portion  212 , and a shape and an orientation of the guide surface  213 . For example, the guide portion  212  is provided so that the wind  165  from the blower unit  160  towards a predetermined target region  201  of the modeled object  200 . Note that, in this case, the wind  165  does not need to be applied to only the target region  201 , and a position, to which the strongest wind  165  is applied, may be in the target region  201 . In addition, a plurality of target regions  201  may be set. 
       FIG.  5    is a diagram illustrating an example of the target region  201 . The drawing illustrates a relationship between an appearance (projection) of the completed modeled object  200 , the target region  201 , and a point  202 , which are viewed from the direction perpendicular to the inner surface  113 . The target region  201  includes, for example, the point  202  farthest to a periphery of the modeled object  200 , that is, the point  202  farthest from the periphery of the modeled object  200  when the modeled object  200  is viewed from the direction perpendicular to the inner surface  113 . In other words, the point  202  is a center of the largest circle of a circle that can be drawn to be inscribed on an edge of the modeled object  200 . The target region  201  is, for example, a region within a circle having a radius r centered on the point  202 . r is not particularly limited, and, for example, may be equal to or larger than 0.1 mm and be equal to or less than 20 mm, or may be equal to or larger than 1 mm and be equal to or less than 10 mm. In such a region, a density of a region where the curable composition  20  is cured is high, and a large amount of reaction heat is generated. Therefore, it is particularly necessary to perform cooling by applying the wind  165 . 
     In addition, when viewed from the direction perpendicular to the inner surface  113 , the target region  201  may include a region that overlaps a region of the modeled object  200  in which a shape accuracy is most required. By doing so, the deformation or the like can be suppressed by particularly releasing the heat from the region in which the shape accuracy is most required. For example, when the modeled object  200  is a mouthpiece or a pseudo tooth, a region, which overlaps a configuration region of an occlusal surface when viewed from the direction perpendicular to the inner surface  113 , can be the target region  201 . The occlusal surface is a so-called tooth-to-tooth meshing part and needs to be formed with high accuracy while having a complicated structure. The region in which the shape accuracy is most required can be determined in advance in comparison with the shape and purpose of the curable composition  20 . 
     In addition, the target region  201  may include a region of the modeled object  200  that is initially exposed from the curable composition  20 . In the three-dimensional modeling apparatus  10  according to the embodiment, the light transmission portion  112  is provided at a bottom of the three-dimensional modeling apparatus  10 , and the modeled object  200  is gradually exposed from below the liquid surface to above the liquid surface of the curable composition  20  in such a way that the carrier  120  is pulled upward as modeling is progressed. The region of the modeled object  200  that is initially exposed from the curable composition  20  is a region of the modeled object  200  that is closest to the surface  122 . Here, when blowing is started toward the region initially exposed from the curable composition  20 , the modeled object  200  can be cooled for a long time. 
     The three-dimensional modeling apparatus  10  according to the embodiment further includes a blowing control unit  162  that controls the blower unit  160 . The blowing control unit  162  controls a timing of blowing from the blower unit  160  based on a timing at which at least a part of the modeled object  200  starts to be exposed from the curable composition  20  in the container  110 . However, it is assumed that the guide portion  212  is formed before the timing at which at least a part of the modeled object  200  starts to be exposed from the curable composition  20  in the container  110 . 
     In a case where the blowing is performed for a long time on the liquid surface of the curable composition  20  before the modeled object  200  is exposed from the curable composition  20 , the temperature of the curable composition  20  decreases, and thus there is a problem in that a modeling speed decreases. Therefore, it is preferable that the blowing is started in consideration of the timing at which the modeled object  200  starts to be exposed from the curable composition  20 . 
     The control unit  140  further controls the blowing control unit  162 . The blowing control unit  162  includes a driving apparatus for the blower unit  160 , and starts and stops blowing of the blower unit  160  under the control of the control unit  140 . The blowing control unit  162  may further control a blowing intensity of the blower unit  160  and an orientation in which the wind  165  is output. 
     In the control unit  140 , the timing at which the modeled object  200  starts to be exposed from the curable composition  20  is calculated based on a liquid surface position of the curable composition  20  in the three-dimensional modeling apparatus  10  and the shapes of the support portion  210  and the modeled object  200  which are modeled on the carrier  120 . In addition, information indicating the timing at which the modeled object  200  starts to be exposed from the curable composition  20  may be held in the storage unit  150  in association with the information indicating the position of the carrier  120 . Further, the control unit  140  controls the blowing control unit  162  to start the blowing of the blower unit  160  before t 1  second from, for example, the timing at which the modeled object  200  starts to be exposed from the curable composition  20 . The t 1  second is, for example, equal to or larger than 0.1 seconds and is equal to or less than 10 seconds. In addition, the control unit  140  controls the blowing control unit  162  to stop the blowing of the blower unit  160  after t 2  second from the completion of the last light irradiation for modeling the modeled object  200 . The t 2  second is, for example, equal to or larger than 0.1 seconds and is equal to or less than 10 seconds. 
     Hereinafter, a method for manufacturing the modeled object  200  according to the embodiment will be described. The method for manufacturing the modeled object  200  according to the embodiment is a method for manufacturing the modeled object  200  using the three-dimensional modeling apparatus  10  as described above. 
     Prior to modeling, three-dimensional data of the modeled object  200  is held in the storage unit  150 . In addition, based on the three-dimensional data of the modeled object  200 , the light irradiation information for modeling the support portion  210 , the guide portion  212 , and the modeled object  200  is generated. Note that, the shapes of the support portion  210  and the guide portion  212  can be determined by a user of the three-dimensional modeling apparatus  10  and can be stored in the storage unit  150 , together with the three-dimensional data of the modeled object  200 . 
     Note that, the user may input information indicating the target region  201  into the three-dimensional modeling apparatus  10 , and the control unit  140  may design the guide portion  212  based on the information indicating the target region  201  so that the wind  165  is applied to the target region  201 . The information indicating the target region  201  is, for example, an image indicating the region when viewed from the direction perpendicular to the inner surface  113 . For example, the control unit  140  can select reference information with that the target region  201  can receive the wind from among a plurality of pieces of reference information indicating the shape, the position, or the like of the guide portion  212  held in advance in the storage unit  150 , and can design the guide portion  212  using the selected reference information. In addition, the control unit  140  may design the guide portion  212  based on a simulation result a flow of the wind  165 . 
     Further, the carrier  120  is disposed in a vicinity of the light transmission portion  112  of the container  110  in which the curable composition  20  is accommodated. At this time, the distance between the surface  122  and the inner surface  113  is, for example, equal to or larger than 30 μm and is equal to or less than 100 μm. 
     Next, the control unit  140  causes the light to be irradiated from the irradiation unit  130  toward the light transmission portion  112  so that the light irradiation is performed on an initial light irradiation region based on the light irradiation information. The curable composition  20  between the surface  122  and the inner surface  113  is irradiated with the light from the irradiation unit  130  via the light transmission portion  112 . Therefore, the curable composition  20  between the surface  122  and the inner surface  113  is cured into a shape of the light irradiation region and the cured substance adheres to the surface  122 . 
     Subsequently, the control unit  140  sequentially performs the light irradiation on the plurality of light irradiation regions based on the light irradiation information. Furthermore, as described above, the control unit  140  controls the driving unit  142  such that the distance between the surface  122  and the inner surface  113  is widened. The cured substance of the curable composition  20 , which is newly formed by the light irradiation, is laminated with respect to the cured substance of the curable composition  20  which is formed immediately before. Note that, at this stage, the cured substance of the curable composition  20  may be in a semi-cured state. 
     The blowing is at least temporarily performed from the blower unit  160  while the modeling is performed in this manner. The wind  165  from the blower unit  160  is guided to the modeled object  200  in such a way that the orientation is changed at the guide portion  212  formed by curing the curable composition  20 . Further, the wind  165  is applied to the surface of the modeled object  200  that faces the surface  122 , and the modeled object  200  is cooled. 
     After the light irradiation is performed on the last light irradiation region, the support portion  210 , the guide portion  212 , and the modeled object  200  are removed from the carrier  120 . Thereafter, there is a case where the support portion  210 , the guide portion  212 , and the modeled object  200  are post-cured. Next, the support portion  210  and the guide portion  212  are removed from the modeled object  200 , and thus the modeled object  200  is obtained. Note that, the support portion  210  and the guide portion  212  may be removed from the modeled object  200  before being post-cured. 
     Next, an operation and effect of the embodiment will be described. According to the embodiment, the wind  165  from the blower unit  160  is at least temporarily output toward at least one of the modeled object  200  and the support portion  210 . In this manner, it is possible to effectively release the heat of the reaction portion from a side of the modeled object  200  while suppressing the decrease in the temperature of the curable composition  20 , and thus it is possible to manufacture the modeled object with a high shape accuracy. 
     Second Embodiment 
       FIG.  6    is a diagram illustrating a structure of a guide portion  212  according to a second embodiment. A three-dimensional modeling apparatus  10  according to the embodiment is the same as the three-dimensional modeling apparatus  10  according to the first embodiment except that the guide portion  212  is provided separately from the support portion  210 . 
     In the embodiment, the guide portion  212  is connected to only one of the carrier  120  and the modeled object  200 . For example, the guide portion  212  is connected to the carrier  120  or the modeled object  200  via a guide support portion  215 . The guide portion  212  may be provided at an end of the guide support portion  215 , or may be provided in the middle of the guide support portion  215 . The drawing illustrates an example in which the guide portion  212  is provided at the end of the guide support portion  215 . The guide portion  212  has the guide surface  213  similarly to the first embodiment. In addition, the guide portion  212  may have a structure added to the guide support portion  215 , or the guide portion  212  may be configured by deforming a part of the guide support portion  215 . Further, one or more guide portions  212  joined to the plurality of guide support portions  215  may be provided. 
     The guide portion  212  and the guide support portion  215  are parts that are removed from the modeled object  200  after the light irradiation is completed with respect to all the light irradiation regions. A shape of the guide support portion  215  is not particularly limited, and is, for example, a column shape, wall shape, a mesh shape, or a lattice shape. The number of guide support portions  215  is not particularly limited, and may be one or more. 
     The guide portion  212  is not particularly limited, and may be, for example, a blade-shaped structure joined to the guide support portion  215 . In addition, the guide portion  212  may be a tapered portion of the guide support portion  215  that becomes thinner toward the modeled object  200 . For example, a relationship between the guide support portion  215  and the guide portion  212  can be represented by replacing the support portion  210  with the guide support portion  215  in the example of the guide portion  212  of the first embodiment. Note that, the guide portion  212  may be provided at the support portion  210  while being provided at the guide support portion  215 . In addition, the guide portion  212  that is joined to both the support portion  210  and the guide support portion  215  may be provided. 
     In addition, the guide portion  212  may be directly joined to the carrier  120  or the modeled object  200 . 
     In a method for manufacturing the modeled object  200  according to the embodiment, the light irradiation information for modeling the support portion  210 , the guide support portion  215 , the guide portion  212 , and the modeled object  200  is generated based on the three-dimensional data of the modeled object  200 . Note that, the shapes of the support portion  210 , the guide support portion  215 , and the guide portion  212  can be determined by the user of the three-dimensional modeling apparatus  10 , and can be stored in the storage unit  150 , together with the three-dimensional data of the modeled object  200 . In addition, similarly to the description according to the first embodiment, the control unit  140  may design the guide support portion  215  and the guide portion  212  based on the information indicating the target region  201  so that the wind  165  is applied to the target region  201 . 
     After the light irradiation is performed on the last light irradiation region, the support portion  210 , the guide support portion  215 , the guide portion  212 , and the modeled object  200  are removed from the carrier  120 . Thereafter, there is a case where the support portion  210 , the guide support portion  215 , the guide portion  212 , and the modeled object  200  are post-cured. Next, the support portion  210 , the guide support portion  215 , and the guide portion  212  are removed from the modeled object  200 , and thus the modeled object  200  is obtained. Note that, the support portion  210 , the guide support portion  215 , and the guide portion  212  may be removed from the modeled object  200  before being post-cured. 
     Note that, in the embodiment, the support portion  210  may not be formed. For example, one part of the modeled object  200  can be directly joined to the surface  122 , and the guide support portion  215  and the guide portion  212  can be formed between another part and the surface  122 . 
     In addition, in the embodiment, the support portion  210 , which is not provided with the guide portion  212 , may be formed separately from the guide support portion  215 . 
     Next, an operation and effect of the embodiment will be described. In the embodiment, the same operation and effect as in the first embodiment can be obtained. In addition, the guide portion  212  can be freely provided independently from the support portion  210 .
