Description

The present invention relates to a laminated modeling technique for forming a three-dimensional model by laminating layers.

The method of dividing 3D CAD (Computer Aided Design) data into layers and adding materials by stacking layers on top of each divided layer to manufacture a 3D model is defined as Adaptive Manufacturing in international standards. Has been done. This manufacturing method, which was invented in the 1980s, is generally called a 3D printer (3D printer). In recent years, 3D printers have been attracting attention as a new manufacturing method because they can easily manufacture complicated shapes without using a mold if they have 3D CAD data.

Unlike removal processing by cutting and molding processing in which a material is poured into a mold and hardened, a 3D printer can easily and accurately manufacture shapes that were once difficult to manufacture, such as mesh shapes and porous shapes. Furthermore, it is also expected to enable a structure in which a plurality of types of materials are freely arranged in a modeled object. This is because, by the structure using a plurality of materials, it is possible to realize a modeled object with a new function that makes the best use of the characteristics of each material.

In the "powder sintering lamination method" in which a powder material is cured and laminated to form a three-dimensional model, the powder material is spread on a molding stage, and a predetermined portion of the spread powder material is irradiated with a laser to perform sintering or Melt hardening. By repeating this process and laminating the cured layers, a modeled object is formed. As the powder material used in this method, not only resin powder but also metal powder can be used. Therefore, the powder sintering lamination method is one of the main modeling methods especially in metal modeling.

In the case of modeling with metal powder, since the melting temperature is high, the temperature distribution inside the modeled object or powder material during modeling becomes large. As a result, warpage deformation occurs in the modeled object due to thermal stress, and the dimensional accuracy of the modeled object deteriorates. In addition, depending on the modeling conditions and the shape of the modeled object, cracks may occur due to thermal stress, resulting in poor modeling.

To solve these problems, Patent Document 1 discloses a method of reducing thermal stress by using a modeling plate that supports a modeled object and releases heat to a modeling stage. According to the method of Patent Document 1, the modeling plate is heat-treated to generate warping deformation due to contraction stress, and the modeling plate is fixed on the modeling stage by positively utilizing the warping deformation of the modeling plate. For this reason, stress is unlikely to remain in the modeled object after the modeling is completed. That is, it is said that the plate warp deformation that occurs when the molding plate is released from being fixed is reduced.

Further, Patent Document 2 discloses a powder sintering layered manufacturing apparatus that makes the temperature of the surface of a thin layer of a powder material uniform over the entire molding region. According to Patent Document 2, when the thin layer of the powder material is sintered, the entire thin layer of the powder material can be sintered more uniformly, so that the sintered thin layer sintered near the boundary of the modeling region can be sintered. The difference in thermal stress is small even when the portion and the portion of the sintered thin layer sintered at the central portion are compared. As a result, warping deformation of the modeled object is suppressed, and highly accurate modeling is possible.

However, in the methods of Patent Documents 1 and 2, the heat of the modeled object is dissipated only to the modeling stage. Therefore, as the number of layers of the cured layer forming the modeled object increases, the heat of the cured layer becomes less likely to be dissipated as the upper layer increases, and the temperature distribution in the modeled object increases. As a result, there is a problem to be solved that the modeled object is warped and deformed due to heat shrinkage after processing and the processing accuracy is lowered.

The present invention has been made in view of the above problems, and an object of the present invention is to efficiently cool a three-dimensional model formed by laminating hardened layers, thereby enabling modeling in which warpage deformation is unlikely to occur. It is an object of the present invention to provide a laminated molding apparatus.

The laminated modeling apparatus of the present invention has a modeling means having a modeling surface for forming a three-dimensional model by laminating hardened layers, a supply means for supplying a predetermined material to the modeling surface, and a predetermined material supplied. A curing means that cures the region of the above to form the cured layer, and a temperature control means that is provided on the material so as to be freely inserted and removed along the molding surface and is inserted into the material to control the temperature of the cured layer. Has.

In the laminated modeling method of the present invention, a predetermined material is supplied to a modeling surface for forming a three-dimensional model by laminating cured layers, and a predetermined region of the supplied material is cured to form the cured layer. The temperature of the cured layer is controlled by inserting the temperature control means provided in the material so as to be freely inserted and removed along the molding surface into the material.

6A to 6D are diagrams for explaining a modeling method by the laminated modeling apparatus 100 of the present embodiment.

FIG. 6A shows the initial stage of modeling of the three-dimensional model 102. First, the powder material 101 is spread over the modeling area 117 to form a material layer, and the material 101 is cured by irradiating a predetermined portion of the material layer with a laser beam. When the modeling of the material layer is completed, the material 101 is spread over the modeling area 117 again to form a new material layer, and the material 101 is cured by irradiating a predetermined portion of the new material layer with laser light to cure the lower cured layer. Integrate with. By repeating this, the three-dimensional model 102 is modeled.

In the initial stage of modeling the three-dimensional model 102 of FIG. 6A, the temperature control rod 108 stands by outside the modeling area 117. At this time, the feed mechanism 110 does not operate, and the movable wall 107 is stopped even if the modeling stage 103 descends each time the material layer is laminated.

FIG. 6B shows a state in which the modeling stage 103 is lowered to the position where the temperature control rod 108 is inserted into the material 101 as the laminated modeling progresses. The position for inserting the temperature control rod 108 can be set in advance in the control unit 114. The control unit 114 interrupts the modeling once the modeling stage 103 reaches a predetermined position, and sends an instruction to insert the temperature control rod 108 into the feed mechanism control unit 111. Upon receiving this instruction, the feed mechanism control unit 111 operates the feed mechanism 110 to insert the temperature control rod 108.

FIG. 6C shows a state in which the temperature control rod 108 has been inserted into the material 101. At this time, the insertion amount of the temperature control rod 108 may be set in advance in the control unit 114 so that the temperature control rod 108 does not collide with the three-dimensional model 102 according to the arrangement of the three-dimensional model 102. can.

After inserting the temperature control rod 108, the temperature in the material layer is detected by the temperature sensor 123 arranged in the temperature control rod 108, and when the next material layer is formed, the laser beam irradiation pattern is based on the detected temperature. And irradiation conditions can be changed. Thereby, the temperature in the material layer can be made uniform. Further, by controlling the current flowing through the heater 121 incorporated in the temperature control rod 108 based on the detected temperature, the temperature in the material layer can be made uniform. When the cooling mechanism is incorporated in the temperature control rod 108, the refrigerant can be circulated when the material layer needs to be cooled, and the refrigerant circulation can be stopped when the material layer needs to be cooled, based on the detected temperature. can. Further, based on the detected temperature, the temperature in the material layer can be made uniform by inserting the temperature control rod 108 at a place where the temperature tends to rise and circulating the refrigerant.

FIG. 6D shows a state in which the three-dimensional model 102 is completed by proceeding with modeling while adjusting the temperature in the material layer as described above. After the temperature control rod 108 is inserted into the modeling area 117, the movable wall 107 is moved up and down in accordance with the raising and lowering of the modeling stage 103 due to the lamination. As a result, the positional relationship between the temperature control rod 108 and the three-dimensional model 102 can be kept constant.

After the modeling is completed, the temperature control rod 108 is removed from the modeling area 117. Even in the middle of modeling, when the temperature control rod 108 is no longer needed, the temperature control rod 108 can be removed from the modeling area 117. Further, the extracted temperature control rod 108 can be inserted into a material layer different from the extracted material layer, for example, a material layer laminated after the extracted material layer.

According to the laminated modeling apparatus 100 of the present embodiment, the heat of the three-dimensional model is not only dissipated to the model stage 103 via the model area 117 in contact with the model, but also the temperature control rod 108 is dissipated from the surface of the model. Is also dissipated. As a result, even when the number of layers of the cured layer forming the modeled object is increased, the heat of the upper layer is dissipated from the surface of the modeled object to the temperature control rod 108, so that the heat of the modeled object is efficiently dissipated and the modeled object is modeled. The temperature distribution inside the object can be reduced. As a result, warpage deformation due to heat of the modeled object is suppressed.

As described above, according to the present embodiment, it is possible to provide a laminated modeling apparatus capable of modeling in which warpage deformation is unlikely to occur by efficiently cooling a three-dimensional model formed by laminating hardened layers. can.
