The present invention relates to a method for manufacturing a three-dimensional model.

Conventionally, a printing device for manufacturing a three-dimensional model has been known (see, for example, Patent Document 1). The printing apparatus described in Patent Document 1 includes a plurality of inkjet heads for ejecting ink, a UV-LED lamp for curing ultraviolet curable ink ejected from the ink jet head, and ink ejected from the ink jet head. It is equipped with a flattening roller that flattens the surface and a mounting portion on which a three-dimensional model is placed. The inkjet head, the UV-LED lamp, and the flattening roller are mounted on the carriage.

The separation layer is formed of ink for a support material, and also functions to support the three-dimensional model from below. Further, when modeling a three-dimensional model with the printing apparatus described in Patent Document 1, a support material for supporting the three-dimensional model is formed so as to surround the outer peripheral surface of the three-dimensional model. The support material is formed of ink for the support material, and supports the overhang portion of the three-dimensional model from below.

It is a side view. FIG. 3 is a table summarizing the results of testing the conditions under which the three-dimensional model is peeled off from the support material during the modeling of the three-dimensional model. FIG. 4 is a graph obtained by graphing the table shown in FIG.

In the method for manufacturing a three-dimensional model of the present embodiment, the ink ejected downward from the inkjet heads 5 to 12 is laminated on the modeling table 4 to manufacture the three-dimensional model 1. The three-dimensional model 1 is, for example, a table having four legs 2 and its top plate is formed in a substantially square flat plate shape. The three-dimensional model 1 is modeled by sequentially laminating inks in the thickness direction of the top plate. In this case, the three-dimensional model 1 is modeled with the top plate side facing down in order to reduce the amount of the support material 3 used.

The ink jet heads 5 to 12 are mounted on the carriage 13. In this embodiment, an ink jet head 5 that ejects support ink, an inkjet head 6 that ejects modeling ink (model material), an inkjet head 7 that ejects white ink, and an ink jet that ejects color ink The heads 8 to 11 and the ink jet heads 12 for ejecting transparent clear ink are mounted on the carriage 13. The ink jet heads 5 to 12 are arranged above the modeling table 4.

The inkjet heads 5 to 12 eject ultraviolet curable ink (UV ink) that cures when irradiated with ultraviolet rays. The carriage 13 is equipped with an ultraviolet irradiator 14 that cures the ink ejected from the inkjet heads 5 to 12. Further, the carriage 13 is equipped with a flattening roller 15 for flattening the surface (upper surface) of the ink ejected from the ink jet heads 5 to 12. The ultraviolet irradiator 14 and the flattening roller 15 are arranged above the modeling table 4. The modeling table 4 is made of a metal such as steel. The upper surface 4a of the modeling table 4 is a plane orthogonal to the vertical direction. An elevating mechanism for raising and lowering the modeling table 4 is connected to the modeling table 4.

In the method for manufacturing a three-dimensional model of this embodiment, ink is laminated on a modeling table 4 to form a three-dimensional model 1 and a support material 3 for supporting the three-dimensional model 1. It has a forming process. The support material 3 is arranged between the three-dimensional model 1 and the model table 4, and surrounds the outer peripheral surface of the three-dimensional model 1. Further, the support material 3 is formed of support ink discharged from the ink jet head 5. The three-dimensional model 1 is mainly formed of ink for modeling ejected from the inkjet head 6, but a part of the three-dimensional model 1 is ejected from the inkjet heads 7 to 12 as needed. It is formed of white ink, color ink, and clear ink.

In the modeling object forming step, first, the inkjet head 5 ejects one layer of ink for a support material. Further, after the ejected ink is irradiated with ultraviolet rays by the ultraviolet irradiator 14 to cure the ink to form one ink layer, the modeling table 4 is lowered by an amount equal to the thickness of the ink layer. This operation is repeated until the support material 3 having a thickness of t1 is formed, and then the ink jet heads 5 to 12 eject one layer of ink. After the ejected ink is irradiated with ultraviolet rays by the ultraviolet irradiator 14 to cure the ink to form one ink layer, the modeling table 4 is lowered by an amount equal to the thickness of the ink layer. This operation is repeated until the three-dimensional model 1 is formed. The thickness of the ink for one layer (thickness of the ink layer) is, for example, 20 to 40 (μm).

The thickness of the support material 3 between the three-dimensional model 1 and the model table 4 (specifically, the vertical direction of the support material 3 between the lower surface of the three-dimensional model object 1 and the upper surface 4a of the model table 4). Thickness) t1 is a thickness capable of suppressing peeling of the three-dimensional modeled object 1 during modeling from the support material 3. Alternatively, the thickness t2 of the support material 3, which is the horizontal distance between the outer peripheral surface of the three-dimensional model 1 and the outer peripheral surface of the support material 3, is the peeling of the three-dimensional model 1 during modeling from the support material 3. It is a thickness that can suppress.

Here, the table of FIG. 3 shows the results of testing the conditions under which the three-dimensional model is peeled off from the support material when the three-dimensional model is modeled. The shape of the three-dimensional modeled object, which is easily warped during modeling and easily peeled off from the support material, is a flat plate shape formed in the horizontal direction. This is because the ultraviolet rays emitted from the ultraviolet irradiator become stronger toward the upper part of the ink layer in each ink layer, so that the shrinkage of the upper part of the ink layer due to ultraviolet curing is the shrinkage of the lower part of the ink layer due to ultraviolet curing. It is thought that it will be larger than.

In the test, a flat plate of 100 mm square (vertical and horizontal widths of 100 mm) in the horizontal direction and a thickness of 4 mm in the vertical direction was modeled as a three-dimensional model, and the support material between the three-dimensional model and the model table was formed. Using the thickness (vertical dimension of the support material) t1 and the thickness of the support material (horizontal dimension) t2, which is the horizontal distance between the outer peripheral surface of the three-dimensional model and the outer peripheral surface of the support material, as parameters. It was confirmed that the three-dimensional model was peeled off from the support material. In the table shown in FIG. 3, "OK" is described in the column for determining the condition that the three-dimensional model does not peel off from the support material, and "OK" is entered in the column for determining the condition that the three-dimensional model has peeled from the support material. Described "NG". FIG. 4 is a graph of the table shown in FIG. As is clear from FIG. 4, if either the thickness t1 or the thickness t2 of the support material is 10 mm or more, it can be seen that peeling of the three-dimensional model from the support material is avoided.

In this embodiment, the vertical width W1 and the horizontal width W2 of the top plate of the three-dimensional model 1 are 100 mm, and the thickness T of the top plate of the three-dimensional model 1 is 4 mm. Therefore, in this embodiment, the thickness t1 of the support material 3 is 10 mm or more in order to suppress the peeling of the three-dimensional modeled object 1 during modeling from the support material 3. Alternatively, in this embodiment, the thickness t2 of the support material 3 is 10 mm or more in order to suppress the peeling of the three-dimensional modeled object 1 during modeling from the support material 3. Specifically, as shown in FIG. 1, the outer peripheral surface of the support material 3 is formed in a conical base surface shape in which the outer diameter gradually decreases toward the upper side, and the thickness of the upper end portion of the support material 3 is formed. t2 is 10 mm or more.

The thickness t1 of the support material 3 is a thickness that can suppress the peeling of the three-dimensional modeled object 1 during modeling from the support material 3, and the thickness t2 of the support material 3 is the three-dimensional object during modeling. The thickness may be such that the separation of the modeled object 1 from the support material 3 can be suppressed. That is, in the present embodiment, the thickness t1 of the support material 3 may be 10 mm or more, and the thickness t2 of the support material 3 may be 10 mm or more.

The critical points of the thicknesses t1 and t2 of the support material 3 as to whether or not the three-dimensional model 1 during modeling is peeled off from the support material 3 are the shape of the three-dimensional model 1, the physical characteristics of the ink, the ink ejection method, and the like. It varies depending on various conditions such as the curing strength of the ink and the scanning speed of the carriage 13. Therefore, it is preferable that the thickness t1 of the support material 3 and / or the thickness t2 of the support material 3 can be set by the operator. Alternatively, the thickness t1 of the support material 3 and / or the thickness t2 of the support material 3 may be automatically changed according to various conditions of the shape of the three-dimensional model 1. According to the study of the inventor of the present application, the thicker the thicknesses t1 and t2 of the support material 3, the more it is possible to suppress the peeling of the three-dimensional model 1 from the support material 3, but from the viewpoint of ink consumption. Therefore, it should be avoided to unnecessarily increase the thicknesses t1 and t2 of the support material 3.

Here, the thickness required for the support material 3 to support the three-dimensional model 1 is generally about 2 mm in order to correspond to various modeling shapes. Further, in order to support the three-dimensional model 1 by laminating ink on the model table 4, first, at least a certain thickness of the support material 3 is provided between the three-dimensional model 1 and the model table 4. It is necessary to form a layer, and the thickness of this layer exceeds the flatness of the upper surface of the modeling table 4. Here, the flatness of the upper surface of the modeling table 4 is the geometrical undulation of the upper surface of the modeling table 4, and is, for example, about 0.3 mm on the upper surface of the modeling table 4 of 500 mm square. Therefore, if the thickness t1 of the support material 3 between the three-dimensional model 1 and the modeling table 4 is 2 mm, the thickness t1 of the support material 3 exceeds the flatness of the upper surface of the modeling table 4, and the support material is used. 3 has a support function for the three-dimensional model 1, but in the present embodiment, the thickness t1 of the support material 3 exceeds the general thickness of 2 mm.

In this embodiment, when the thickness t1 of the support material 3 is such a thickness that can suppress the peeling of the three-dimensional modeled object 1 from the support material 3 during modeling, the thickness t1 of the support material 3 is the support material 3. Is thicker than the thickness required to support the three-dimensional model 1. Further, when the thickness t2 of the support material 3 is such that the peeling of the three-dimensional model 1 during modeling from the support material 3 can be suppressed, the thickness t2 of the support material 3 is such that the support material 3 is tertiary. The thickness exceeds the thickness required to support the original model 1. That is, when the thickness t2 of the support material 3 is such a thickness that the peeling of the three-dimensional model 1 during modeling from the support material 3 can be suppressed, the support material 3 is originally a three-dimensional model. The area required to support 1 extends outward in the radial direction of the three-dimensional model 1.

(Main effect of this form)
As described above, in the method for manufacturing a three-dimensional model of the present embodiment, the thickness t1 of the support material 3 between the three-dimensional model 1 and the model table 4 is the thickness t1 of the three-dimensional model 1 being modeled. The thickness is such that peeling from the support material 3 can be suppressed. Alternatively, in the method for manufacturing a three-dimensional model of the present embodiment, the thickness t2 of the support material 3, which is the horizontal distance between the outer peripheral surface of the three-dimensional model 1 and the outer peripheral surface of the support material 3, is the tertiary during modeling. The thickness is such that the peeling of the original model 1 from the support material 3 can be suppressed. Therefore, when the three-dimensional model 1 is manufactured by the method for manufacturing the three-dimensional model of the present embodiment, it is possible to prevent the three-dimensional model 1 during modeling from peeling off from the support material 3.

In particular, in this embodiment, the thickness t1 of the support material 3 between the three-dimensional model 1 and the modeling table 4 is 10 mm or more, or the thickness t2 of the support material 3 is 10 mm or more. Therefore, according to the study of the inventor of the present application, the amount of deformation of the support material 3 capable of following the deformation of the three-dimensional model 1 during modeling is made larger, and the three-dimensional model 1 during modeling is transferred from the support material 3. It becomes possible to effectively suppress the peeling.

In this embodiment, if the support material 3 can form the three-dimensional model 1 even if the support material 3 does not surround the outer peripheral surface of the three-dimensional model 1, the support material 3 is the three-dimensional model. It is not necessary to surround the outer peripheral surface of 1. That is, the support material 3 may be arranged only between the three-dimensional model 1 and the model table 4.

(Modification example of manufacturing method of 3D model)
In the above-mentioned form, in the modeling object forming step, depending on the shape of the three-dimensional modeling object 1, the three-dimensional modeling object 1 being modeled may be peeled off from the support material 3. When the three-dimensional model 1 is peeled off from the support material 3 in the model forming step, the three-dimensional model 1 and the support material 3 are removed from the modeling table 4 (removal step), and the support material 3 is removed after the removal step. The thickness t1 of the above is changed to be thicker than the thickness t1 of the support material 3 in the modeling object forming process, and the ink is laminated on the modeling table 4 again to form the three-dimensional modeling object 1 and the support material. 3 and 3 may be formed (second model formation step).

Specifically, when the three-dimensional model 1 is peeled off from the support material 3 in the model forming step, the thickness t1 of the support material 3 is set to be thicker in the second model forming step, and the ink is applied again. The three-dimensional model 1 and the support material 3 may be formed by laminating them on the modeling table 4. In this case, in the second modeled object forming step, the amount of deformation of the support material 3 that can follow the deformation of the three-dimensional modeled object 1 during modeling is increased, and the three-dimensional modeled object 1 during modeling is the support material 3. It becomes possible to suppress peeling from.

Further, when the three-dimensional model 1 is peeled off from the support material 3 in the model forming step, the thickness t2 of the support material 3 becomes thicker than the thickness t2 of the support material 3 in the model forming step after the removal step. The setting may be changed as described above, and the ink may be laminated on the modeling table 4 again to form the three-dimensional modeling object 1 and the support material 3 (second modeling object forming step). Specifically, when the three-dimensional model 1 is peeled off from the support material 3 in the model forming step, the thickness t2 of the support material 3 is set to be thicker in the second model forming step, and the ink is applied again. The three-dimensional model 1 and the support material 3 may be formed by laminating them on the modeling table 4.

Even in this case, in the second modeled object forming step, the amount of deformation of the support material 3 that can follow the deformation of the three-dimensional modeled object 1 during modeling is increased, and the three-dimensional modeled object 1 during modeling is supported. It becomes possible to suppress peeling from the material 3. That is, even in this case, the amount of deformation of the support material 3 capable of following the deformation of the three-dimensional model 1 during modeling is increased, and the three-dimensional model 1 during modeling is peeled off from the support material 3. Can be suppressed.

Further, when the three-dimensional model 1 is peeled off from the support material 3 in the model forming step, the thickness t1 of the support material 3 and the thickness t2 of the support material 3 are set larger after the removal step, and the thickness t2 of the support material 3 is set to be larger again. Ink may be laminated on the modeling table 4 to form the three-dimensional modeling object 1 and the support material 3. In this case, it is effective to increase the amount of deformation of the support material 3 that can follow the deformation of the three-dimensional model 1 during modeling, and to separate the three-dimensional model 1 during modeling from the support material 3. It becomes possible to suppress it.

In the above-described form, the thickness t1 of the support material 3 may be less than 10 mm and the thickness t2 of the support material 3 may be less than 10 mm depending on the shape of the three-dimensional model 1. Further, in the above-mentioned form, the three-dimensional model 1 may be an object other than the table. Further, the three-dimensional model 1 does not have to have a flat plate-shaped portion such as a table top plate.
