In describing the following characteristic embodiments, various specific contents are written in order to more specifically describe the utility model and to help understanding the utility model. However, when describing the present invention, well-known parts that are not significant to the present invention are not described in order to prevent confusion in describing the present invention.
Next, a method for producing a three-dimensional model according to an embodiment of the present invention will be described.
In the present invention, as shown in fig. 1, a plurality of sheet-like members R1, R2, R3, R4, L1, L2, L3, and L4, each of which is made of a corrugated cardboard, are prepared, and each of the sheet-like members has an outline of a cross-sectional shape of an object at a predetermined interval with respect to an arbitrary axial direction of the object, and a three-dimensional model a corresponding to the object is completed by an accumulation process in which surfaces of adjacent sheet-like members among the plurality of sheet-like members are bonded and fixed. In other words, the present invention is to complete the three-dimensional model through the above-described addition process of stacking and joining a plurality of sheet-like members having an outer contour of a cross-sectional shape corresponding to the object. At this time, the bonding of the sheet-like members may be achieved by an adhesive.
In the present invention, as shown in fig. 2, a guide line G is formed on one of a pair of facing surfaces of the adjacent sheet-like members R2 and R3, so that when two sheet-like members R2 and R3 are joined, the other sheet-like member R3 can be arranged and joined and fixed according to the guide line G formed on the one sheet-like member R2, and therefore, the sheet-like members can be easily joined at an accurate position.
In addition, as shown in fig. 3, when the adjacent sheet-like members L1, R1 are the same size during assembly, holes H are punched in the same positions of the respective sheet-like members L1, R1 in order to easily find the coupling arrangement positions, and thus can be used as reference points. Meanwhile, in the present invention, as shown in fig. 3, one sheet member R1 may be constituted as a first portion R1a and a second portion R1b in a form capable of being separated from each other. The first portion R1a and the second portion R1b may be separated from and coupled to each other by a coupling structure formed with grooves and protrusions.
The utility model discloses in, with the light-weighted board that has regulation thickness, the condition of the preparation that the slice component was realized to corrugated container board promptly, compare with the condition of using other paper types, because corrugated container board has bigger thickness, so can reduce the required number of slice component of three-dimensional model preparation, in addition, compare with other paper types, corrugated container board's price is cheaper, simultaneously, when using useless corrugated container board, can reduce material cost absolutely.
The utility model discloses in, in order to make the three-dimensional model, through following process: in order to prepare a sheet-like member, an outline of a virtual three-dimensional model corresponding to an object is extracted at predetermined intervals along an arbitrary axial direction of the virtual three-dimensional model by computer three-dimensional modeling, the extracted outline is printed on a corrugated cardboard sheet, and the corrugated cardboard sheet is cut along the outline.
Specifically, referring to fig. 4 and 11, a step of aligning the sheet member will be described.
As shown in fig. 4, a virtual three-dimensional model 10 of an object is created by computer three-dimensional modeling. As shown in fig. 5, the virtual plane 20 of the virtual solid model 10 is created, the outline line 30 is extracted, and then, as shown in fig. 6, transformed into a spline curve 40 and stored.
Next, as shown in fig. 7 and 8, the next outer contour line 30-1 is extracted at the next interval in the axial direction, and then transformed into a spline curve 40-1 and stored.
Next, the process of extracting the outer contour lines at predetermined intervals in the outward direction with the shaft as the center, converting the extracted outer contour lines into spline curves, and storing the spline curves is repeated, and finally, as shown in fig. 9, the axially outermost outer contour lines 30 to 12 are extracted, and as shown in fig. 10, the extracted outer contour lines are converted into spline curves 40 to 12, and stored.
Next, as shown in fig. 11, the spline curves 40-1 to 40-12 extracted by the method described above are arranged.
Next, a pair of spline curves adjacent to each other among the arranged plurality of spline curves 30-1 to 30-12 is printed on a corrugated cardboard. Although not shown, if explained in more detail, a pair of spline curves adjacent to each other is printed on the respective corrugated cardboards by printing a first spline curve and a second spline curve on the first corrugated cardboard and a second spline curve and a third spline curve on the second corrugated cardboard. In this case, of the pair of spline curves printed on one corrugated cardboard, the spline curve printed on the outer side becomes a cutting line, and the spline curve printed on the inner side becomes a guide line.
Next, in the corrugated board printed with the spline curve, cutting is performed along a cutting line, so that respective sheet-like members (corresponding to the respective sheet-like members R1, R2, R3, R4.., L1, L2, L3, L4.. shown in fig. 1) can be prepared.
The sheet-like member manufactured through the step of preparing the sheet-like member as described above is bonded and combined in a laminated manner using an adhesive (stacking process), so that the three-dimensional model using the corrugated cardboard of the present invention can be manufactured. At this time, the sheet-like members are bonded by arranging the other sheet-like member in accordance with the guide line formed on one of the adjacent sheet-like members and bonding with the adhesive, so that the sheet-like members can be bonded at an accurate position. Further, when adjacent sheet members of the same size are initially bonded, the respective formed holes are aligned, and the two sheet members are aligned and then bonded.
In the above-described embodiment of the present invention, the board for producing the sheet-like member is exemplified by a corrugated cardboard, but the present invention is not limited thereto, and may be made of a lightweight material, that is, a styrofoam or a wood material.
On the other hand, as shown in fig. 1 to 11, a three-dimensional model a according to an embodiment of the present invention includes a plurality of sheet-like members R1, R2, R3, R4.., L1, L2, L3, and L4.., each of which has an outer contour line 30 of a cross-sectional shape of an object at a predetermined interval with respect to an arbitrary axial direction of the object, and a guide line G corresponding to the outer contour line 30 of the other sheet-like member is formed on any one of two adjacent sheet-like members, and the two adjacent sheet-like members are fixed in such a manner that the outer contour line 30 is aligned with and bonded to the guide line G.
Next, a method for producing a three-dimensional model according to another embodiment of the present invention will be described.
In this method, the sheet member preparation step is completely the same as the sheet member preparation step of the previous embodiment except for the via hole forming process and the identification symbol printing process on the sheet member, and therefore, the same steps will not be described again, and only the via hole forming process and the identification symbol printing process will be described.
As shown in fig. 12 to 18, on a plurality of sheet-like members formed by cutting along cutting lines, characters a for identification for identifying an assembly order and an assembly direction are printed, respectively, for example, "R1", "R2", "R3", "R4". the identification characters "L1", "L2", "L3", "L4". the identification characters a are printed corresponding to reference numerals of the sheet-like members, wherein the identification characters a may be omitted on the sheet-like member located at the outermost end, for example, "R11" and "L11" are omitted, thereby ensuring neat appearance of the assembled three-dimensional model while facilitating assembly.
Next, the guide holes b are formed at predetermined positions of all the sheet-like members except for the sheet-like member at the outermost end portion.
Next, the sheet-like member formed with the guide hole b is inserted into the guide rod c in a close-fitting manner in a predetermined order and direction, and then the sheet-like member at the outermost end is arranged and fixed in accordance with the guide wire G on the sheet-like member.
However, as shown in fig. 15, when the direction of the recognition character a on one sheet-like member does not match the direction of the recognition character a on the other sheet-like member, the sheet-like member cannot be aligned with the guide hole b of the other sheet-like member, and the sheet-like member cannot be inserted into the guide c, in this case, the sheet-like member having a direction different from the direction of the recognition character a of the other sheet-like member needs to be rotated until the direction of the recognition character a is the same.
Therefore, in the assembly process, the assembly order and the assembly direction of the sheet-like members can be quickly determined based on the recognition characters, thereby improving the assembly speed of the three-dimensional model.
On the other hand, as shown in fig. 12 to 18, a three-dimensional model according to another embodiment of the present invention includes a plurality of sheet-like members R1, R2, R3, R4.., L1, L2, L3, and L4.., each of which has an outer contour line 30 of a cross-sectional shape of an object at a predetermined interval with respect to an arbitrary axial direction of the object, and a guide line G corresponding to the outer contour line of the other sheet-like member is formed on any one of two adjacent sheet-like members, and guide holes b are formed at predetermined positions of all the sheet-like members except for the sheet-like member at the outermost end; and a guide rod c inserted into the guide hole b in a tight fit manner to connect the adjacent sheet-like members, wherein the sheet-like member at the outermost end is adhesively fixed to the guide line G on the sheet-like member adjacent thereto.
In addition, the guide hole b and the guide rod c are rectangular in cross section.
Further, the length of the guide bar c is equal to the laminated thickness of all the sheet-like members except the sheet-like member at the outermost end.
The sheet member is any one of a corrugated cardboard, a polystyrene foam board, and a wood board.
The present invention has been described above with reference to the accompanying drawings, but the present invention is not limited to the embodiments and drawings disclosed in the present specification, and various modifications can be made by those skilled in the art within the scope of the technical idea of the present invention.
