Description

  The present invention relates to an auxiliary tool, a 3D printer, and a cell board with an auxiliary function, and more particularly, to an auxiliary tool, a 3D printer, and a cell board with an auxiliary function that facilitate removal of a model from the cell board.

  In a 3D printer, it is known that a cell board is installed on a platform of a 3D printer main body, and a model is formed on the cell board. Here, generally, a plurality of through-holes are formed in the cell board for the purpose of preventing peeling during modeling. Such a through-hole prevents the modeled object from being peeled off during modeling because part of the bottom surface of the modeled object flows into the through-hole during modeling. On the other hand, the fact that part of the bottom surface of the modeled object flows into the through hole has also become a factor that makes it difficult to peel off after modeling.

  As a technique for dealing with such a problem, for example, there is Japanese Patent No. 6176663. Japanese Patent No. 6176663 describes a jig used in combination with the cell board as described above. Specifically, according to Japanese Patent No. 6,176,643, a jig for a 3D printer includes a flat plate having a plurality of convex portions formed on the surface, which are inserted into openings that are through holes formed in a cell board, and a cell. And a spacer inserted between the board and the flat plate. According to Japanese Patent No. 6176663, with the above-described configuration, the spacer is set during modeling and the spacer is removed after modeling to prevent peeling of the modeled object from the cell board during modeling, while modeling after modeling. Objects can be easily detached from the cell board.

FIG. 8 is a cross-sectional view showing an example of another configuration of the cell board 21. 9 and 10 are diagrams illustrating an example of another configuration of the 3D printer 1.

  In the first embodiment, an auxiliary cell board 2 (cell board with auxiliary function) installed in the 3D printer 1 will be described. The 3D printer 1 models the model 3 on the cell board 2 with assistance. The cell board 2 with assistance in this embodiment is a cell board which has the removal function used when removing the molded article 3 formed on the cell board as an auxiliary function. For example, the cell board 2 with assistance is formed by attaching the first auxiliary base 22 or the second auxiliary base 23 to the cell board 21. As will be described later, by properly using the base attached to the cell board 21 between the first auxiliary base 22 and the second auxiliary base 23, it is possible to prevent the molded article 3 from being peeled off during modeling, and the molded article after modeling. Can be easily removed.

  FIG. 1 shows an example of the configuration of a 3D printer 1 on which an auxiliary cell board 2 described in the present embodiment is installed. As shown in FIG. 1, the 3D printer 1 includes a base 11, a rail 12 formed on the base 11, nozzles 13 provided on the rail 12, and a substantially rectangular platform 14. . Further, the cell board 2 with assistance is installed on the platform 14.

  For example, the 3D printer 1 melts a wire (filament) -like material (for example, ABS resin or PLA resin) with heat, and controls the driving of the rail 12 and the platform 14 while extruding the material from the nozzle 13. Are stacked on the cell board 2 with assistance to form a model 3.

  Note that the configuration itself of the 3D printer 1 may be a known one. The 3D printer 1 may have a configuration other than the configuration shown in FIG. A detailed description of the 3D printer 1 is omitted.

  The cell board 2 with assistance is installed on the platform 14. The cell board 2 with assistance is formed by attaching auxiliary tools to the cell board 21. For example, the cell board 2 with assistance includes a cell board 21 and a first auxiliary base 22 (first plate-like member) that is a deterring means, or a second auxiliary base 23 (second plate) that is an extrusion means. ), And any one of them. In other words, the auxiliary cell board 2 has either a structure in which the first auxiliary base 22 is attached from below the cell board 21 or a structure in which the second auxiliary base 23 is attached from below the cell board 21. Have.

  FIG. 2 is a perspective view illustrating an example of the configuration of the cell board 21, the first auxiliary base 22, and the second auxiliary base 23.

  The cell board 21 is, for example, a resin flat plate having a substantially rectangular shape in plan view. The cell board 21 has, for example, the same shape as the platform 14.

  As shown in FIG. 2, the cell board 21 is, for example, a resin plate-like member 211 in which a plurality of through holes 212 are formed. The number of through holes 212 formed in the plate-like member 211 and the interval between the through holes 212 may be arbitrarily set. For example, FIG. 2 shows an example in which through holes 212 are formed in the plate-like member 211 at equal intervals in the vertical and horizontal directions. However, the through holes 212 are not necessarily formed in the plate-like member 211 at equal intervals.

  As described above, one of the first auxiliary base 22 and the second auxiliary base 23 can be attached to the cell board 21. Specifically, for example, by inserting a convex portion 223 included in the first auxiliary base 22 described later into each of the plurality of through holes 212 formed in the plate-like member 211, the first on the cell board 21. An auxiliary base 22 can be attached. Further, for example, the second auxiliary base 23 is inserted into the cell board 21 by inserting a convex portion 233 of a second auxiliary base 23 described later into each of the plurality of through holes 212 formed in the plate-like member 211. Can be attached.

  The first auxiliary base 22 is a substantially plate-like member having a shape equivalent to the cell board 21, for example. The first auxiliary base 22 may be made of resin or metal.

  Referring to FIG. 2, the first auxiliary base 22 includes a cover plate 221, a bottom plate 222, and a plurality of convex portions 223. The first auxiliary base 22 has a convex portion 223 at a position corresponding to the formation location of the through hole 212 formed in the plate-like member 211. As described above, by using the first auxiliary base 22 having the convex portion 223 corresponding to the formation location of the through hole 212, the first auxiliary base 22 has in each of the through holes 212 formed in the cell board 21. The convex part 223 can be inserted.

  FIG. 3 is a cross-sectional view showing an example of the configuration of the first auxiliary base 22 in more detail. Referring to FIG. 3, a through-hole through which the convex portion 223 is inserted is provided at a position corresponding to the formation location of the through-hole 212 formed in the plate-like member 211 in the lid plate 221. In addition, the lid plate 221 and the bottom plate 222 are each formed with a concave portion used when the convex portion 223 is installed. For example, in the lid plate 221 and the bottom plate 222, when the lid plate 221 and the bottom plate 222 are overlapped, a space is formed between the lid plate 221 and the bottom plate 222 according to the shape of the convex portion 223 described later. A recess is formed. By forming the recesses in the lid plate 221 and the bottom plate 222 in this manner, the convex portion 223 can be sandwiched between the lid plate 221 and the bottom plate 222.

  The convex portion 223 has a wide head and a cylindrical portion. The convex portion 223 is manufactured, for example, by cutting off a sharp tip portion of a metal nail. In addition, the cylindrical part of the convex part 223 may have shapes other than a cylinder, such as a prismatic shape such as a triangular prism or a quadrangular prism.

  As shown in FIG. 3, the convex portion 223 is sandwiched between the cover plate 221 and the bottom plate 222 in a state where the head portion is located below. The cylindrical portion of the convex portion 223 has the same outer diameter as the through hole formed in the lid plate 221, and is inserted through the through hole formed in the lid plate 221. Further, the head located below the convex portion 223 is sandwiched between the cover plate 221 and the bottom plate 222. In this manner, the convex portion 223 can be prevented from coming off by sandwiching the head portion of the convex portion 223 between the cover plate 221 and the bottom plate 222.

  The length from the upper end of the convex part 223 to the upper part of the cover plate 221 (that is, the length of the part that enters the through-hole 212 formed in the cell board 21; hereinafter referred to as the stroke length) is the second described later. It is shorter than the length of the stroke of the convex part 233 which the auxiliary base 23 has. In other words, it can be said that the length of the convex portion 223 excluding the head portion is shorter than the length of the convex portion 233 excluding the head portion. For example, the length of the stroke of the convex part 223 is about ½ of the depth of the through hole 212 which is the thickness of the cell board 21. Thus, the convex part 223 has a length that fills a part of the through hole 212 when the convex part 223 is inserted into the through hole 212. In addition, as long as the length of the convex part 223 is a length which fills a part of through-hole 212, it may be other than what was illustrated, such as about 1/3 of the through-hole 212, for example.

  The first auxiliary base 22 can be formed as follows, for example. First, the convex portion 223 is installed in each of the plurality of concave portions formed in the bottom plate 222. Subsequently, the cover plate 221 is covered from above so that a columnar portion of the convex portion 223 described later passes through a through hole formed in the cover plate 221. Accordingly, the convex portion 223 is sandwiched and fixed between the cover plate 221 and the bottom plate 222. According to such a configuration, for example, the first auxiliary base 22 can remove the arbitrary convex portion 223 by removing the cover plate 221. As a result, for example, only the worn convex portion 223 can be easily replaced. In other words, it can also be said that the first auxiliary base 22 is formed so that only an arbitrary convex portion 223 among the plurality of convex portions 223 can be replaced.

  The above is an example of the configuration of the first auxiliary base 22. The configuration of the first auxiliary base 22 described above is merely an example. The first auxiliary base 22 may have a configuration other than that described above.

  For example, it is assumed that the first auxiliary base 22 has the concave portions used when the convex portions 223 are installed in the cover plate 221 and the bottom plate 222. However, the concave portion used when installing the convex portion 223 may be formed only in one of the cover plate 221 and the bottom plate 222.

  Moreover, the convex part 223 does not necessarily need to be formed interchangeably. That is, the first auxiliary base 22 may have a configuration in which a plurality of convex portions are integrally formed on a flat plate.

  The second auxiliary base 23 is a substantially plate-like member having a shape equivalent to that of the cell board 21, for example, similarly to the first auxiliary base 22. The second auxiliary base 23 may be made of resin or metal.

  Referring to FIG. 2, the second auxiliary base 23 includes a cover plate 231, a bottom plate 232, and a plurality of convex portions 233 (long convex portions). FIG. 4 is a cross-sectional view showing an example of the configuration of the second auxiliary base 23 in more detail. As shown in FIG. 4, the convex portion 233 is fixed by being sandwiched between the cover plate 231 and the bottom plate 232 in a state where the head portion is located below. As described above, the second auxiliary base 23 has the same configuration as that of the first auxiliary base 22. On the other hand, as will be described later, the second auxiliary base 23 and the first auxiliary base 22 are different in the stroke length of the convex portion.

  Similar to the convex portion 223, the convex portion 233 has a wide head and a cylindrical portion. The convex part 233 is manufactured, for example, by cutting off the tip part of a metal nail. The cylindrical portion of the convex portion 233 may have a shape other than the cylindrical shape such as a prismatic shape such as a triangular prism or a quadrangular prism as in the case of the convex portion 223.

  As described above, the length of the stroke of the convex portion 233 is longer than the length of the stroke of the convex portion 223 included in the first auxiliary base 22. That is, the length of the convex portion 233 excluding the head portion is longer than the length of the convex portion 223 excluding the head portion. For example, the length of the stroke of the convex part 233 is substantially the same as the depth of the through hole 212 which is the thickness of the cell board 21. Thus, the convex part 233 has such a length that the through hole 212 is filled when the convex part 233 is inserted into the through hole 212. In addition, the length of the convex part 233 may be longer than the depth of the through-hole 212, for example.

  The second auxiliary base 23 can be formed by the same method as the first auxiliary base 22. First, the convex portion 233 is installed in each of the plurality of concave portions formed in the bottom plate 232. Subsequently, the cover plate 231 is covered from above so that a cylindrical portion of the convex portion 233 described later passes through a through hole formed in the cover plate 231. Accordingly, the convex portion 233 is sandwiched and fixed between the lid plate 231 and the bottom plate 232. According to such a configuration, for example, the second auxiliary base 23 can remove the arbitrary convex portion 233 by removing the cover plate 221, similarly to the first auxiliary base 22. As a result, for example, only the worn protrusion 233 can be easily replaced. As described above, the second auxiliary base 23 is formed so that an arbitrary convex portion 233 can be replaced in the same manner as the first auxiliary base 22.

  The above is an example of the configuration of the second auxiliary base 23. It should be noted that the second auxiliary base 23 can employ various modified examples in the same manner as the first auxiliary base 22.

  The cell board 2 with assistance includes a cell board 21 having the above-described configuration, and a first auxiliary base 22 or a second auxiliary base 23.

  Subsequently, an example of the operation until the modeled object 3 is removed after the modeled object 3 is modeled on the cell board 21 will be described with reference to FIGS. 5 to 7. FIG. 5 is a cross-sectional view showing an example of a state when the model 3 is modeled on the cell board 21. FIG. 6 is a cross-sectional view illustrating an example of a state when removing a modeled object. FIG. 7 is a flowchart illustrating an example of an operation when removing a modeled object after modeling it on the cell board 21.

  Referring to FIG. 7, the first auxiliary base 22 is attached to the cell board 21 (step S101). Thereafter, the cell board 2 with assistance formed by attaching the first auxiliary base 22 to the cell board 21 is installed on the platform 14.

  The 3D printer 1 models the model 3 on the cell board 2 with assistance (step S102). FIG. 5 shows an example of a state when modeling a modeled object in this way. Referring to FIG. 5, the convex portion 223 is inserted into a part of the through hole 212 formed in the plate-like member 211 of the cell board 21. Due to such a configuration, when the model 3 is modeled on the cell board 2 with assistance, a part of the bottom surface of the model 3 flows into the portion of the through-hole 212 where the convex part 223 is not inserted. . Thereby, the modeling object 3 is prevented from peeling during the modeling of the modeling object 3. In other words, it can also be said that the convex portion 223 has a height corresponding to the length of the convex portion 223 in the through hole 212 and suppresses the flow of the molded article 3 during modeling into the through hole 212.

  After modeling the molded article 3, the first auxiliary base 22 is removed from the cell board 21 of the cell board 2 with assistance, and the second auxiliary base 23 is attached to the cell board 21. As described above, the second auxiliary base 23 has the convex portion 233 whose stroke length is substantially the same as the depth of the through hole 212 that is the thickness of the cell board 21. Therefore, as shown in FIG. 6, when the second auxiliary base 23 is attached to the cell board 21, the model 3 is lifted up. Thus, after modeling the modeling object 3, the modeled modeling object 3 is extruded by attaching the 2nd auxiliary base 23 to the cell board 21 (step S103). Thereby, it becomes possible to remove the molded article 3 easily.

  As described above, the cell board 2 with assistance is formed by attaching any one of the first auxiliary base 22 and the second auxiliary base 23 to the cell board 21. In this way, by properly using the first auxiliary base 22 and the second auxiliary base 23, it is possible to prevent the model 3 from peeling off during modeling, and to easily remove the model 3 after modeling. Become. For example, by using the first auxiliary base 22 during modeling of the modeled object 3, it is possible to prevent the modeled object 3 from peeling off during modeling of the modeled object 3. Moreover, it becomes possible to peel the modeling thing 3 easily by using the 2nd auxiliary base 23 after modeling of the modeling article 3. FIG.

  Moreover, the cell board 2 with assistance in this embodiment has implement | achieved the said effect, without using a spacer. That is, the above effect can be realized without being affected by the deterioration of the spacer. As a result, the effects as described above can be realized without the possibility of the modeling of the model 3 being affected by the deterioration of the spacer.

  Moreover, the 1st auxiliary | assistant base 22 in this embodiment is comprised so that the arbitrary convex part 223 can be replaced | exchanged, and the 2nd auxiliary | assistant base 23 is comprised so that the arbitrary convex part 233 can be replaced | exchanged. Due to such a configuration, according to the first auxiliary base 22 and the second auxiliary base 23 in the present embodiment, when some of the convex portions 223 and the convex portions 233 are deformed or damaged, the deformed or damaged It is possible to exchange only a part of the convex portions 223 and the convex portions 224 where the occurrence of the above-mentioned occurs. That is, it is not necessary to replace the entire first auxiliary base 22 or the second auxiliary base 23 due to deformation or breakage of some of the convex portions 223 or the convex portions 233.

  Various modifications can be adopted for the cell board 21. FIG. 8 shows an example of a modification of the cell board 21.

  For example, referring to FIG. 8, the through hole 212 may be formed with a nut 213 in which the inner diameter of the through hole 212 increases as it goes above a predetermined position. That is, the upper part of the through hole 212 may be inclined outward. By providing the nut 213 in the through-hole 212, it becomes possible to remove the molded article 3 more easily. Further, the cell board 21 may be passed through the heating wires 214 in a lattice shape, for example. By passing the heating wire 214 through the cell board 21, the temperature of the cell board 21 can be raised by energization. Thereby, it becomes possible to remove the molded article 3 more easily. Further, when the cell board 21 is pushed down with a finger when removing the modeled object 3, the force concentrates on several points, and the cell board 21 may be distorted, making it difficult to remove the modeled object 3. In order to deal with such a fear, an extrusion assisting tool 215 having a substantially rectangular shape and a predetermined height in a plan view may be provided on both end sides of the cell board 21 which are opposite sides in a plan view. . The extrusion assisting tool 215 is made of the same material as that of the cell board 21, for example, and assists when the cell board 21 is pushed downward. By providing the extrusion assisting tool 215 in this way, it becomes possible to press the cell board 21 uniformly by pushing the extrusion assisting tool 215, and it becomes possible to remove the molded article 3 more easily. In addition, the shape of the extrusion assistance tool 215 is not limited to the case illustrated above. The extrusion assisting tool 215 can take various forms that can assist in pushing the cell board 21 in the extrusion direction (for example, downward).

  In addition, when providing the NUKI 213 and the heating wire 214 on the cell board 21, it is possible to easily form the molded article 3 without using the first auxiliary base 22 and the second auxiliary base 23 as described in this embodiment. It can be removed. Therefore, the auxiliary function of the auxiliary cell board 2 may be realized by at least one of the nut 213 and the heating wire 214.

  The 3D printer 1 can also employ various modifications. For example, the 3D printer 1 has a function of moving the cell board 2 with assistance (moving means), a function of changing the base attached to the cell board 21 between the first auxiliary base 22 and the second auxiliary base 23, A function (detachment means) for removing the molded article 3 using the second auxiliary base 23 can be provided. The above function is controlled by, for example, an arithmetic device (not shown) included in the 3D printer 1 executing a program stored in a storage device (not shown).

  9 and 10 show modified examples of the 3D printer 1. FIG. 9 shows an example of the 3D printer 1 viewed from the side, and FIG. 10 shows an example of the 3D printer 1 viewed from above. Referring to FIG. 9, moving means such as a rail that goes around the 3D printer 1 is provided on the front surface, back surface, and side surface of the 3D printer 1, and the cell board 2 with assistance is attached using the moving means. Move. For example, the moving means such as a rail has a locking means such as a locking piece that is locked by a method such as sandwiching the cell board 2 with assistance (the shape and size of the locking piece are arbitrary). It does not matter. The cell board 2 with assistance can be prevented from falling from the 3D printer 1 even when it is moved below the 3d printer by the moving means by being locked by the locking means.

  Further, the 3D printer 1 has a detaching unit for exchanging the auxiliary base and detaching the modeled object 3. For example, the detaching means may be a hook that holds a movable part that moves up and down the columnar part (rail 12) of the main body of the 3D printer 1 and both side surfaces of the cell board 21 that is different from the traveling direction of the cell board 21 from above and below. Stop piece). The removing means moves the cell board 21 up and down by moving the hook up and down while the cell board 21 is sandwiched between the hooks. Thus, by moving the cell board 21 up and down, the detaching means replaces the auxiliary base attached to the cell board 21. For example, the detaching means replaces the auxiliary base located on the lower side of the cell board 21 with the cell board 21 moved upward. Thereafter, the removing means moves the cell board 21 downward to attach the replaced auxiliary base 2 to the cell board 21. Thereby, the removing means can exchange the auxiliary base attached to the cell board 21 between the first auxiliary base 22 and the second auxiliary base 23. In the case shown in FIG. 9, the detaching means may be configured to replace the auxiliary base at a location where the modeled object is modeled and below the site where the modeled object is modeled. Alternatively, as shown in FIG. 9, the removing means may perform replacement of the auxiliary base or removal of the modeled object 3 at an intermediate position when the auxiliary cell board 2 is rotated once. The removal means may be a known one such as a robot arm or use of weight.

  Note that the 3D printer 1 may include, for example, a moving unit formed in an oval shape, an oval shape, a circular shape, or the like in plan view as illustrated in FIG. Also in the case illustrated in FIG. 10, the 3D printer 1 can perform replacement of the auxiliary base, removal of the modeled object 3, and the like in the same manner as described above. In the case shown in FIG. 10, the 3D printer 1 has a stick that pushes out the model 3 in a direction different from the traveling direction of the cell board 21 or a shovel that scoops the model 3 as a means for removing the model separated from the cell board 21. You may have.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a cross-sectional view showing an example of the configuration of the third auxiliary base 24 having the first bottom plate 242. FIG. 12 is a cross-sectional view showing an example of a configuration in which the first bottom plate 242 is replaced with the second bottom plate 244 in the third auxiliary base 24. FIG. 13 is a cross-sectional view showing an example of a state when the convex portion 243 is pushed out using the second bottom plate 244. FIG. 14 is a cross-sectional view showing an example of a state when the model 3 is modeled on the cell board 21. FIGS. 15 and 16 are cross-sectional views illustrating an example of a state when the modeled object 3 is removed. FIG. 17 is a flowchart illustrating an example of the operation from the modeling of the model 3 on the cell board 21 to the removal.

  In the second embodiment, a third auxiliary base 24 (third plate-like member) that can be employed instead of the first auxiliary base 22 and the second auxiliary base 23 will be described. As will be described later, the third auxiliary base 24 is configured to be able to change the stroke length of the convex portion 243 by properly using the first bottom plate 242 and the second bottom plate 244. Specifically, as will be described later, the third auxiliary base 24 is configured to be able to move the convex portion 243 in the vertical direction, and by moving the convex portion 243 in the vertical direction, The stroke length of the part 243 is changed. In this way, by using the third auxiliary base 24 in which the stroke length of the convex portion 243 can be changed, the first implementation can be performed without using a plurality of bases as described in the first embodiment. It is possible to exert the same effect as the form.

  The third auxiliary base 24 is a substantially plate-like member having a shape equivalent to that of the cell board 21, for example. For example, the third auxiliary base 24 is thicker than the first auxiliary base 22 and the second auxiliary base 23. The third auxiliary base 24 can be attached to the cell board 21 instead of the first auxiliary base 22 and the second auxiliary base 23. The third auxiliary base 24 may be made of resin or metal. Note that the third auxiliary base 24 may have the same thickness as the first auxiliary base 22 and the second auxiliary base 23, or the first auxiliary base 22 and the second auxiliary base 23. Can be thicker.

  The third auxiliary base 24 includes a cover plate 241, a bottom plate, and a convex portion 243. The third auxiliary base 24 can use any one of the first bottom plate 242 and the second bottom plate 244 as a bottom plate. As will be described later, the first bottom plate 242 is a flat plate. Since the flat plate is used, when the first bottom plate 242 is used as the bottom plate, the convex portion 243 cannot be pushed upward by pushing the first bottom plate 242 from below. Therefore, the convex part 243 is positioned below in the range that can move in the vertical direction. The first bottom plate 242 is used, for example, when the model 3 is modeled. Moreover, as will be described later, the second bottom plate 244 is a bottom plate with convex portions having irregularities. For example, the 2nd bottom plate 244 has the extrusion convex part which is a convex part which pushes the convex part 243 upwards in the location according to the convex part 243. FIG. In this way, by using the second bottom plate 244 having the extrusion convex portion as the bottom plate, the convex portion 243 can be moved in the vertical direction. Thereby, the length of the stroke of the convex part 243 is changed. The second bottom plate 244 is used, for example, when the model 3 is removed after the model 3 is modeled.

  11 to 13 are cross-sectional views showing an example of the configuration of the third auxiliary base 24 in more detail. FIG. 11 shows an example of the configuration of the third auxiliary base 24 when the first bottom plate 242 that is a flat plate is used as the bottom plate. 12 and 13 show an example of the configuration of the third auxiliary base 24 when the second bottom plate 244 having irregularities is used as the bottom plate.

  Referring to FIG. 11, a through-hole through which the convex portion 243 is inserted is provided at a position corresponding to the formation location of the through-hole 212 formed in the plate-like member 211 in the cover plate 241. In addition, the lid plate 241 has a concave portion used when the convex portion 243 is installed. The cover plate 241 in the present embodiment is thicker than, for example, the cover plate 221 and the cover plate 231 described in the first embodiment, and the concave portion formed in the cover plate 241 is a convex portion described later. It is formed to be deeper than the thickness of the head 243.

  Similarly to the first auxiliary base 22 and the second auxiliary base 23, the third auxiliary base 24 also has a lid so that a cylindrical portion of a convex portion 243 described later passes through a through hole formed in the cover plate 241. It is formed by sandwiching a convex portion 243 between the plate 241 and the first bottom plate 242. Here, as described above, the lid plate 241 in the present embodiment has a thickness as compared with the lid plate 221 and the lid plate 231, and the lid plate 241 has a deeper recess. Accordingly, as shown in FIG. 11, when the convex portion 243 is sandwiched between the lid plate 241 and the first bottom plate 242, a space S1 is formed between the head of the convex portion 243 and the lid plate 241. Become. The space S1 is a space required when the convex portion 243 is moved in the vertical direction. That is, by forming the space S1 between the head of the convex portion 243 and the cover plate 241, the convex portion 243 can move in the vertical direction. Note that the cylindrical portion of the convex portion 243 may have a shape other than the cylindrical shape, such as a prismatic shape such as a triangular prism or a quadrangular prism, similarly to the convex portion 233 or the convex portion 223.

  Thus, the convex part 243 is sandwiched between the lid plate 241 and the first bottom plate 242 so as to be movable. Moreover, when the 1st bottom plate 242 is used, the convex part 243 is located below among the ranges which move to an up-down direction.

  Referring to FIG. 12, the second bottom plate 244 is a bottom plate with convex portions having irregularities. A convex portion 243 is provided in a portion where the extruded convex portion is formed in the second bottom plate 244, and a space S <b> 2 is formed between the concave portion and the lid plate 241. By forming the second bottom plate 244 in this manner, as shown in FIG. 13, the convex portion 243 is pushed by the extruded convex portion by pressing the lid plate 241 downward or pushing the second bottom plate 244 upward. Can be pushed upward. Thereby, the stroke length of the convex part 243 can be increased.

  The convex part 243 has the head part formed wide and the cylindrical part similarly to the convex part 223 and the convex part 233. The convex portion 243 is manufactured, for example, by cutting off the tip portion of a metal nail.

  The convex portion 243 is sandwiched between the lid plate 241 and the bottom portion (the first bottom plate 242 or the second bottom plate 44) with the head portion positioned below. The cylindrical portion of the convex portion 243 has the same outer diameter as the through hole formed in the lid plate 241 and is inserted through the through hole formed in the lid plate 241. Further, the head portion located below the convex portion 243 is sandwiched between the lid plate 241 and the bottom plate (the first bottom plate 242 or the second bottom plate 244).

  The convex part 243 has, for example, the same length as the convex part 233 described in the first embodiment. Therefore, for example, when the convex part 243 is pushed upward as shown in FIG. 13, the length of the stroke of the convex part 243 is substantially the same as the depth of the through-hole 212 which is the thickness of the cell board 21, for example. It becomes. On the other hand, when the first bottom plate 242 is used as the bottom plate as shown in FIG. 11, the convex portion 243 is positioned below. In such a case, only a part of the convex portion 243 is located above the cover plate 241 and the stroke length is shorter than when the convex portion 243 is pushed upward. Thus, when the first bottom plate 242 and the like are used, the length of the stroke of the convex portion 243 is, for example, about ½ of the depth of the through hole 212 that is the thickness of the cell board 21. Thus, the convex part 243 performs the piston movement which is the movement in the up and down direction, so that the stroke length of the convex part 243 is approximately half the depth of the through hole 212 to the depth of the through hole 212. Change to In addition, as for the length of the stroke changed when the convex part 243 moves up and down, various modifications may be adopted as in the first embodiment.

  The third auxiliary base 24 has a configuration as described above, for example.

  Subsequently, with reference to FIG. 14 to FIG. 17, an example of operation until the modeled object 3 is removed after the modeled object 3 is modeled on the cell board 21 when the third auxiliary base 24 is used will be described. To do. FIG. 14 is a cross-sectional view showing an example of a state when the model 3 is modeled on the cell board 21. FIG. 15 and FIG. 16 are cross-sectional views showing an example of a state when removing a modeled object. FIG. 17 is a flowchart illustrating an example of an operation when removing a modeled object after modeling the cell board 21.

  Referring to FIG. 17, the third auxiliary base 24 having the first bottom plate 242 is attached to the cell board 21 (step S201). Thereafter, the cell board 2 with assistance formed by attaching the third auxiliary base 24 having the first bottom plate 242 to the cell board 21 is installed on the platform 14. Since the bottom plate of the third auxiliary base 24 is the first bottom plate 242, the length of the stroke of the convex portion 243 is, for example, about 1/2 of the depth of the through hole 212 which is the thickness of the cell board 21. It becomes.

  The 3D printer 1 models the model 3 on the cell board 2 with assistance (step S202). FIG. 14 shows an example of a state when modeling a modeled object. Referring to FIG. 14, the convex portion 243 is inserted through a part of the through hole 212 formed in the plate-like member 211 of the cell board 21. Due to such a configuration, when the model 3 is modeled on the cell board 2 with assistance, a part of the bottom surface of the model 3 flows into a portion of the through-hole 212 where the convex portion 243 is not inserted. . Thereby, the modeling object 3 is prevented from peeling during the modeling of the modeling object 3. As described above, when the first bottom plate 242 is used, the stroke length of the convex portion 243 is, for example, about ½ of the depth of the through hole 212 that is the thickness of the cell board 21. . Therefore, the convex portion 243 is inserted into a part of the through hole 212.

  After modeling the model 3, the bottom plate is changed from the first bottom plate 242 to the second bottom plate 244 as shown in FIG. 15. Then, for example, by pushing down the cell board 21, the convex portion 243 is pushed out further than the cover plate 241. Thereby, for example, the length of the stroke of the convex portion 243 becomes substantially the same as the depth of the through hole 212 which is the thickness of the cell board 21. As a result, as shown in FIG. 16, the modeled object 3 is lifted up. Thus, after modeling the modeled object 3, the modeled model 3 is extruded by changing the bottom plate to the second bottom plate 244 and extruding the convex portion 243 (step S303). Thereby, it becomes possible to remove the molded article 3 easily.

  As described above, the third auxiliary base 24 is configured such that the stroke length of the convex portion 243 can be changed. Thus, the same effect as that of the first embodiment can be obtained by using the third auxiliary base 24 instead of the first auxiliary base 22 and the second auxiliary base 23.

  Note that the second embodiment can adopt a modification similar to that of the first embodiment. For example, also in the second embodiment, a modification of the cell board 21 as shown in FIG. 8 may be adopted. Similarly, the 3D printer 1 may adopt a modification. In the case of the present embodiment, in the modified example of the 3D printer 1, for example, the first bottom plate 242 and the second bottom plate 244 are exchanged.

  Further, for example, the third auxiliary base 24 may have only the second bottom plate 244 without having the first bottom plate 242. When the third auxiliary base 24 does not have the first bottom plate 242, the third auxiliary base 24 has a locking means for locking the lid plate 241 and the second bottom plate 244 in the state shown in FIG. It will be necessary. As the locking means, various known means that can be locked with the lid plate 241 and the second bottom plate 244 with a gap between the lid plate 241 and the second bottom plate 244 may be used. The locking means has, for example, the same thickness as the gap formed between the lid plate 241 and the second bottom plate 244, and at least one of the gaps formed between the lid plate 241 and the second bottom plate 244. It may be inserted into the part. The locking means may be formed on the side surfaces of the lid plate 241 and the second bottom plate 244, for example.

  Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above-described embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
