According to the present embodiment, since the bonding portion 40 includes the first bonding portion 41 and the second bonding portion 42, the insert member 30 can be more firmly bonded to the resin laminate 20. Thereby, the displacement of the position of the insert member 30 with respect to the resin laminate 20 can be further suppressed.

The molded body 10 of the present embodiment is manufactured, for example, using an inkjet 3D printer. As shown in FIG. 3, the method of manufacturing the molded body 10 of the present embodiment includes a first molding step S1, an adhesion step S2, and a second molding step S3. As shown in FIG. 4, the first molding step S1 is a step of laminating the resin layers 20a in the vertical direction, and molding the first laminated portion 21 shown in FIG.

As shown in FIG. 5, the first stacked portion 21 has a groove 53 and a recess 60 recessed downward. The groove 53 is recessed downward from the bottom surface of the recess 60. The inner surface of the recess 60 constitutes a part of the inner surface of the housing 50. The inner surface of the recess 60 includes the side surface 51, the contact surface 52 and the inner surface of the groove 53. The side surface 51 is a surface of the inner surface of the recess 60 that is located in a direction perpendicular to the vertical direction.

As shown in FIG. 4, in the first forming step S1, the operator moves the ink head IH of the 3D printer in the direction perpendicular to the vertical direction to produce the resin layer 20a. First, the operator applies the uncured resin from the nozzle N of the ink head IH and moves the ink head IH to the right in FIG. 4 to produce the uncured resin layer 20b. Next, as shown in FIG. 4, the worker moves the ink head IH to the left side of FIG. 4 and flattens the uncured resin layer 20 b with the roller R, while irradiating the ultraviolet light UV from the irradiation portion L And the uncured resin layer 20b is cured. Thereby, the resin layer 20a is produced. The worker repeats the above procedure to form a plurality of resin layers 20 a stacked in the vertical direction, and shapes the first stacked portion 21.

The bonding step S2 is a step of disposing the insert member 30 in the recess 60 and bonding the inner surface of the recess 60 and the insert member 30 with the adhesive 70. As shown in FIG. 3, the bonding step S2 includes an insert member arranging step S2a and an adhesive injection step S2b.

In the insert member disposing step S2a, the operator inserts the insert member 30 into the inside of the recess 60 from the upper side of the first stacked portion 21, as shown in FIG. As shown in FIG. 6, the worker places the insert member 30 by bringing the lower surface 31 of the insert member 30 into contact with the contact surface 52 and separating the side surface 33 of the insert member 30 from the side surface 51 of the recess 60. That is, a gap is provided between the side surface 51 and the disposed insert member 30. Thereby, when the insert member 30 is arrange | positioned in the recessed part 60, it can suppress that air accumulates with the contact surface 52 of the insert member 30, and it can suppress that the insert member 30 floats up.

In the insert member disposing step S2a, the worker inserts the groove 53 at a position where a part of the groove 53 opens in the gap between the side surface 51 and the insert member 30, and the other part of the groove 53 faces the lower surface 31 of the insert member 30. Position the member 30. In the present embodiment, the outer edge portion of the groove 53 opens in the gap between the side surface 51 and the insert member 30, and the inner edge portion of the groove 53 faces the lower surface 31 of the insert member 30. A gap is provided between the bottom surface and the lower surface 31 at the inner edge portion of the groove 53. By arranging the insert member 30 in this manner, the groove 53 can be prevented from being sealed by the insert member 30. Therefore, the uncured adhesive 70 can be injected into the groove 53. In the present embodiment, the upper surface 32 of the insert member 30 and the upper surface of the first stacked unit 21 are disposed, for example, on the same plane orthogonal to the vertical direction.

In the adhesive injection step S2b, the operator injects the uncured adhesive 70 into the gap between the side surface 51 and the insert member 30 from the upper side of the recess 60. The injection of the uncured adhesive 70 is performed, for example, using a dispenser D. The uncured adhesive 70 injected into the gap between the side surface 51 and the insert member 30 flows into the groove 53 from the gap between the side surface 51 and the insert member 30. Thus, in the bonding step S2, the worker injects the uncured adhesive 70 into the groove 53 from between the side surface 51 and the insert member 30.

The uncured adhesive 70 injected into the groove 53 flows under the lower surface 31 of the insert member 30 in the groove 53. Thus, in the bonding step S2, the operator injects the uncured adhesive 70 into the gap between the bottom surface of the recess 60 and the lower surface 31 of the insert member 30. As shown in FIG. 7, the injected uncured adhesive 70 cures to form an adhesive 40. Thereby, the adhesion part 40 is produced.

Here, in the adhesive injection step S2b, the operator injects the uncured adhesive 70 to a position lower than the upper surface of the first laminated portion 21. That is, in the bonding step S <b> 2, the upper surface of the injected adhesive 70 is located below the upper surface of the first stacked portion 21. Thereby, as shown in FIG. 7, the gap G is provided on the upper side of the adhesive 70 or the adhesive portion 40 where the adhesive 70 is cured.

The second molding step S3 is a step of laminating the resin layer 20a on the upper side of the first laminated portion 21 and forming the second laminated portion 22 at least a part of which is disposed on the upper side of the insert member 30. The operator moves the ink head IH in the direction perpendicular to the vertical direction to produce the resin layer 20a and form the second laminated portion 22 in the same manner as in the first forming step S1. At this time, the uncured resin flows into the gap G. The uncured resin that has flowed into the gap G becomes the contact portion 23 by curing. By the steps described above, the resin laminate 20 is produced, and the molded body 10 is produced.

According to the present embodiment, since the insert member 30 is bonded to the first stacked portion 21 in the bonding step S2, the recess 60 is performed before performing the second molding step S3 or when performing the second molding step S3. It can suppress that the position of the insert member 30 inserted inside slip | deviates. Thereby, the displacement of the position of the insert member 30 with respect to the resin laminate 20 can be suppressed.

Moreover, it can suppress that the insert member 30 inserted in the recessed part 60 floats up etc., and protrudes above the 1st lamination | stacking part 21. As shown in FIG. Therefore, when producing the resin layer 20a laminated | stacked on the upper side of the 1st lamination | stacking part 21 in 2nd shaping | molding process S3, it can suppress that the shape of the resin layer 20a becomes distortion. Therefore, the molding accuracy of the resin laminate 20 can be improved, and the molding accuracy of the molded body 10 can be improved.

In particular, in the case where the molded body 10 is manufactured using an inkjet 3D printer as in the present embodiment, the ink head IH interferes with the insert member 30 when the insert member 30 protrudes above the first stacked portion 21. In some cases, the resin layer 20a can not be produced. Therefore, the effect that can suppress that the insert member 30 mentioned above protrudes above the 1st lamination | stacking part 21 is acquired useful especially, when shape | molding the molded object 10 using 3D of inkjet type. The case where the insert member 30 inserted into the recess 60 floats up is the case where the recess 60 is smaller than the insert member 30, and the insert member 30 is press-fit into the recess 60.

Further, according to the present embodiment, the bonding portion 40 has the first bonding portion 41 disposed between the side surface 51 and the insert member 30. Therefore, as described above, when the uncured adhesive 70 is injected, a method of injecting the uncured adhesive 70 from the upper side of the recess 60 of the first laminated portion 21 into the gap between the side surface 51 and the insert member 30 is disclosed. It can be adopted. That is, even after the insert member 30 is disposed in the recess 60, an injection port for injecting the adhesive 70 into the recess 60 can be provided. Thus, the adhesive 70 can be easily injected.

Also, for example, when the adhesive 70 is injected to the same position as the upper surface of the first stacked portion 21 in the vertical direction, the second molding step S3 is performed in a state where the upper end of the adhesive 70 is not cured. If done, the upper end of the adhesive 70 may be deformed and protrude above the first stacked portion 21. In addition, the adhesive 70 may overflow from the recess 60 and adhere to the upper surface of the first stacked unit 21. Therefore, the molding accuracy of the resin layer 20a laminated on the upper side of the adhesive 70 may be reduced.

On the other hand, according to the present embodiment, the upper surface of the injected adhesive 70 is located lower than the upper surface of the first stacked portion 21 in the bonding step S2. Therefore, even if the second molding step S3 is performed when the upper end of the injected adhesive 70 is not cured, the upper end of the adhesive 70 protrudes above the first stacked portion 21. Can be suppressed. Moreover, it can suppress that the unhardened adhesive agent 70 overflows from the recessed part 60 in adhesion process S2. Thereby, it can suppress that the shaping | molding precision of the resin layer 20a in 2nd shaping | molding process S3 falls, and it can suppress that the shaping | molding precision of the molded object 10 falls. Incidentally, by adopting such a method, the resin flows into the gap G in the second molding step S3 and directly on the upper side of the first adhesive portion 41 without the intervention of the side surface 33 of the insert member 30 and the adhesive portion 40. The contact part 23 which contacts is provided.

For example, after applying the uncured adhesive 70 to the bottom of the recess 60, the insert member 30 is inserted into the recess 60 from above the applied adhesive 70, and the insert 70 is recessed by the adhesive 70. It is also conceivable to adhere to the bottom of the However, in this case, since the insert member 30 is positioned with respect to the first stacked portion 21 via the uncured adhesive 70, it may be difficult to position the insert member 30 with high accuracy. In addition, the position of the insert member 30 may be shifted before the adhesive 70 cures. Moreover, in this case, the position of the insert member 30 may be shifted and the insert member 30 may be protruded above the first stacked portion 21 in some cases. Therefore, the molding accuracy of the resin layer 20a in the second molding step S3 may be reduced, and the molding accuracy of the molded body 10 may be reduced.

On the other hand, according to the present embodiment, in the bonding step S2, in a state where the insert member 30 is in contact with the contact surface 52 which is the bottom surface of the recess 60, the inner surface of the recess 60 and the insert member 30 The uncured adhesive 70 is injected into the gap between Therefore, the insert member 30 can be positioned with respect to the first stacked portion 21 with high accuracy. Further, since the adhesive 70 is injected after the insert member 30 is in contact with the contact surface 52, the adhesive 70 can be prevented from entering between the insert member 30 and the contact surface 52, and the position of the insert member 30 is shifted. Can be suppressed. Thereby, it can suppress more that the position of the insert member 30 shifts | deviates with respect to the resin laminated body 20, and it can suppress that the shaping | molding precision of the molded object 10 falls.

Further, according to the present embodiment, the first laminated portion 21 is provided with the groove 53 which is recessed downward from the bottom surface of the recess 60. Therefore, by injecting the adhesive 70 into the groove 53, the lower surface 31 of the insert member 30 can be bonded to the first laminated portion 21 while the insert member 30 is brought into contact with the contact surface 52 and positioned as described above. it can. Thereby, the insert member 30 can be more firmly adhered to the first stacked portion 21.

The present invention is not limited to the above-described embodiment, and other configurations can be adopted. The insert member may be partially embedded in the resin laminate. In this case, the other part of the insert member is exposed to the outside of the resin laminate. Another part of the insert member may protrude to the outside of the resin laminate. The insert member may not be made of metal as long as the material is different from that of the resin laminate. The insert member may be, for example, a ceramic, or may be a resin different from the material of the resin laminate. The shape of the insert member is not particularly limited.
