Thereafter, the nozzle surface is wiped with a wiper 63 in order to form a meniscus of the nozzle (the inside of the nozzle is under negative pressure). Further, the maintenance mechanism 61 prevents the nozzle surfaces of the first head 21 and the second head 22 from being covered and dried when the model material 201 and the support material 202 are not discharged.

  Next, a first embodiment of the present invention will be described with reference to FIG. 5 and FIG. FIG. 5 is an explanatory view for explaining the rotational phase of the flattening roller in the embodiment, and FIG. 6 is a schematic cross-sectional explanatory view for similarly explaining the laminated state of the layered product.

  In the present embodiment, when the surface of the nth layer model material 201 continuous in the stacking direction is planarized and when the surface of the n + 1th layer model material 201 is planarized, The rotation phase of the flattening roller 23 in the moving direction (main scanning direction) is controlled to be the same.

  For example, the control unit 500 sets the movement start position of the carriage 20 to the same position in the nth layer and the n + 1th layer based on the detection signal of the linear encoder 30, and the flattening roller 23 based on the detection signal of the rotary encoder 33. Control of setting the rotation start position of the same position in the nth layer and the (n + 1) th layer.

  Thus, when the surface of the model material 201 forming the n-th layer on the modeling stage 11 is flattened, the lower end of the flattening roller 23 is displaced as shown by a solid line in FIG.

  When the surface of the model material 201 forming the (n + 1) th layer is flattened, the movement start position of the carriage 20 and the rotation start position of the flattening roller 23 are made the same as the nth layer, respectively. The lower end of the developing roller 23 is displaced as shown by a broken line in FIG.

  That is, when the nth layer is flattened and when the n + 1th layer is flattened, the rotation phase of the flattening roller 23 in the moving direction (main scanning direction) of the flattening roller 23 is the same. .

  The present embodiment will be specifically described with reference to FIG. Here, an example in which model material shaped articles 201A and 201B are sequentially stacked on the modeling stage 11 will be described. In this example, the model material model 201A is the nth layer, and the model material model 201B is the n + 1th layer.

  First, as shown in FIG. 6A, the model material 201 serving as the nth layer is ejected from the first head 21 toward the modeling stage 11. Then, as shown in FIG. 6B, the flattening roller 23 brings the n-th layer model material 201 into contact and flattening, and the curing unit 24 cures the n-th layer model material shaped object 201A. Form.

  Here, when flattening is performed by the flattening roller 23, the lower end of the flattening roller 23 is displaced in the moving direction of the flattening roller 23 due to rotational deflection of the flattening roller 23 or the like. Therefore, asperities are generated on the surface of the flattened model material molded object 201A at the pitch following the displacement of the lower end of the flattening roller 23.

  Next, as shown in FIG. 6C, the model material 201 to be the (n + 1) th layer is discharged from the first head 21 onto the model material formed object 201A of the nth layer toward the formation stage 11. Then, as shown in FIG. 6D, the flattening roller 23 brings the (n + 1) th layer model material 201 into contact and flattening, and the curing unit 24 cures the n + 1th layer model material shaped object 201B. Form.

  Here, the flattening roller 23 in the moving direction (main scanning direction) of the flattening roller 23 when flattening the model material 201 of the nth layer and when flattening the model material 201 of the (n + 1) th layer. Control so that the rotational phases of

  As a result, on the surface of the planarized model material shaped object 201B of the (n + 1) th layer, an unevenness corresponding to the displacement of the lower end of the flattening roller 23 is generated in the same phase as the model material shaped object 201A of the nth layer.

  As described above, the displacement of the lower end of the flattening roller 23 caused by the deflection or the like of the flattening roller 23 in two layers continuous in the stacking direction is overlapped. In other words, the surface of the n-th layer model material shaped object 201A after curing is transferred with the deflection of the flattening roller 23, and the unevenness corresponding to the rotation pitch is generated, but the n + 1th layer model material When the surface 201 is flattened, the unevenness due to the swing of the flattening roller 23 becomes the same as the nth layer which is the lower layer.

  Thereby, when flattening the model material shaped object 201B of the (n + 1) th layer, the flattening roller 23 does not interfere with the cured model material shaped object 201B of the nth layer which is the lower layer, and flattening is performed. The lower layer is prevented from being scraped or noise is generated.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a schematic cross-sectional explanatory view to be used for explaining the layered state of the layered three-dimensional object in the same embodiment.

  Here, an example in which the model material shaped objects 201A, 201B, and 201C are sequentially stacked on the modeling stage 11 will be described. In this example, the model material structure 201C is the final surface layer of the three-dimensional structure.

  And in this embodiment, it is considered as composition which does not perform flattening by flattening roller 23 about model material fabrication thing 201C which is a layered fabrication thing used as the outermost surface of a three-dimensional fabrication thing.

  That is, as shown in FIG. 7A, model material shaped articles 201A and 201B are sequentially stacked on the modeling stage 11 in the same manner as in the first embodiment. At this time, in flattening when forming the model material shaped articles 201A and 201B, the rotation phases of the flattening roller 23 are made to coincide.

  And as shown in FIG.7 (b), the model material 201 used as the last layer is discharged on the model material molded article 201B. Thereafter, as shown in FIG. 7C, the model material shaped object 201C which is cured by the curing unit 24 and becomes the outermost surface of the three-dimensional object is formed without flattening the model material 201.

  Thereby, the unevenness of the lower layer due to the deflection of the flattening roller 23 can be filled with the layered object of the final layer forming the surface of the three-dimensional object, and the quality of the object of the three-dimensional object can be improved. In addition, when it hardens without planarizing, the outer peripheral part of the last layer will be in the shape which swelled, but if it is one to several layers, the quantity will be small and it will not lead to the fall of modeling quality.

  Next, a third embodiment of the present invention will be described with reference to FIGS. 8 and 9. FIG. 8 is an explanatory diagram for explaining the rotational phase of the flattening roller in the same embodiment, and FIG. 9 is a schematic cross-sectional explanatory diagram for explaining the laminated state of the layered product.

  In the present embodiment, when the surface of the nth layer model material 201 continuous in the stacking direction is planarized and when the surface of the n + 1th layer model material 201 is planarized, Control is performed so that the rotation phase of the flattening roller 23 in the movement direction (main scanning direction) is different, that is, the rotation phase is shifted.

  For example, the control unit 500 sets the movement start position of the carriage 20 to the same position in the nth layer and the n + 1th layer based on the detection signal of the linear encoder 30, and the flattening roller 23 based on the detection signal of the rotary encoder 33. Control is performed to set different rotation start positions of the nth layer and the (n + 1) th layer.

  Thus, when the surface of the model material 201 forming the nth layer on the modeling stage 11 is flattened, the lower end of the flattening roller 23 is displaced as shown by a solid line in FIG.

  When the surface of the model material 201 forming the (n + 1) th layer is planarized, for example, the movement start position of the carriage 20 is made the same as the nth layer, and the rotation start position of the flattening roller 23 is different from the nth layer. By setting the position, the lower end of the flattening roller 23 is displaced as shown by a broken line in FIG.

  That is, when the nth layer is planarized and when the n + 1th layer is planarized, the rotational phase of the planarizing roller 23 in the moving direction (main scanning direction) of the planarizing roller 23 is different. Here, the phase is shifted by 180 ° between the time of planarizing the nth layer and the time of planarizing the n + 1th layer.

  The present embodiment will be specifically described with reference to FIG. Here, an example in which the model material shaped objects 201A, 201B, and 201C are sequentially stacked on the modeling stage 11 will be described. In this example, the model material model 201A is the n-1st layer, the model material model 201B is the nth layer, and the model material model 201C is the n + 1th layer.

  First, referring to FIG. 9A, the model material 201 serving as the n-1st layer is ejected from the first head 21 toward the shaping stage 11, and the flattening roller 23 makes the n-1th layer. It is brought into contact with the model material 201 and flattened. Then, it is cured by the curing unit 24 to form the model material shaped article 201A of the (n-1) th layer.

  The model material 201 to be the n-th layer is discharged from the first head 21 onto the model material modeling object 201A of the n-1st layer, and is brought into contact with the model material 201 on the n-th layer by the flattening roller 23 Flatten. Then, it is cured by the curing unit 24 to form the n-th model material model 201B.

  In this case, as in the first embodiment, when the n-1st layer and the nth layer are planarized, the moving direction of the flattening roller 23 in the n-1th layer and the nth layer (the main The rotational phase of the flattening roller 23 in the scanning direction is made to coincide. As a result, on the surface of the planarized model material shaped object 201B of the n-th layer, for example, unevenness corresponding to the displacement of the lower end of the flattening roller 23 is generated in a rotational phase as shown by the solid line in FIG.

  Next, referring to FIG. 9B, the model material 201 to be the (n + 1) th layer is discharged from the first head 21 on the model material shaped object 201B of the nth layer. Then, as shown in FIG. 9C, the flattening roller 23 brings the (n + 1) th layer model material 201 into contact and flattening, and the curing unit 24 cures the n + 1th layer model material shaped object 201C. Form.

  When the n + 1 th layer is flattened, as shown by the broken line in FIG. 8, the flattening roller 23 is moved in the moving direction (main scanning direction) of the n + 1 th layer, as shown by the broken line in FIG. The rotation phase is shifted and flattened.

  Thereby, the lower end of the flattening roller 23 generated on the surface of the (n + 1) th layer in the moving direction of the flattening roller 23 with respect to the unevenness corresponding to the displacement of the lower end of the flattening roller 23 generated on the surface of the nth layer The position of the unevenness corresponding to the displacement of is shifted.

  Therefore, the unevenness of the surface of the model material shaped object 201B of the (n + 1) th layer is reduced, and the surface accuracy is improved.

  Therefore, when the final layer forming at least the outermost surface of the three-dimensional object is the n + 1th layer, the rotational phase of the flattening roller is different from when flattening the lower n-th layer, three-dimensional modeling The surface accuracy of the outermost surface of the object can be improved.

  In this case, in the (n + 1) th layer, it is preferable to set the scraping amount of the model material 201 by the flattening roller 23 (the biting amount of the model material 201 of the flattening roller 23) smaller than the nth layer. As a result, when the n + 1 th layer is flattened, the flattening roller 23 is prevented from interfering with the hardened n-th model material shaped article.

  Further, the control to make the rotational phase of the flattening roller 23 (rotating member) different and the control to reduce the bite amount of the model material 201 of the flattening roller 23 are not limited to shaping the layered object forming the outermost surface. By applying to several layers near the outermost surface, a higher quality surface can be obtained.

  Here, although an example in which the rotational phase of the flattening roller 23 is different by 180 ° between the nth layer and the n + 1st layer is described, the present invention is not limited to 180 °, and the nth layer and the n + 1th layer are described. By shifting the rotational phase of the flattening roller 23 in layers, the surface accuracy of the (n + 1) th layer can be improved.

  Moreover, in the said embodiment, although the layered molded article is demonstrated by the example comprised only with a model material modeled article, as demonstrated in FIG. 3, when a layered molded article is comprised with a model material and a support material Again, the invention is equally applicable. In the above embodiment, although the example in which the forming liquid is applied using the liquid discharge head is described, the forming liquid may be applied using an application means other than the liquid discharge head, such as a dropping means. it can.
