Description

  The present invention relates to an additive manufacturing technique of laminating layers to form a three-dimensional object.

  Three-dimensional CAD (Computer Aided Design) data is divided into layers, and the method of adding materials by layering layers on divided layers and adding materials to produce three-dimensional shaped objects is defined as Additive Manufacturing in the international standard. It is done. This manufacturing method invented in the 1980's is generally called a 3D printer (3D printer). The 3D printer has been attracting attention as a new manufacturing method in recent years because it can easily manufacture complicated shapes without using a mold if it has 3D CAD data.

  In the 3D printer, unlike the reductive processing by cutting and the molding processing in which the material is poured into a mold and solidified, it is possible to easily and accurately manufacture a shape that was once difficult to manufacture, including a mesh shape and a porous shape. Furthermore, it is also expected to enable a structure in which a plurality of types of materials are freely arranged in a shaped object. This is because the structure using a plurality of materials can realize a three-dimensional object having a new function utilizing the characteristics of the respective materials.

  In the “powder sinter lamination method” in which powder materials are cured and laminated to form a three-dimensional object, the powder stage is spread on the formation stage, and laser irradiation is performed on a predetermined portion of the spread powder material or It melts and hardens. This is repeated to form a shaped object by laminating the cured layer. Not only resin powder but also metal powder can be used as the powder material used in this method. Therefore, the powder sinter lamination method has become one of the main forming methods in metal forming.

  At the time of shaping by metal powder, since the melting temperature is high, the temperature distribution inside the shaped article or powder material during shaping becomes large. As a result, warpage occurs due to thermal stress in the shaped article, and the dimensional accuracy of the shaped article is degraded. In addition, depending on the forming conditions and the shape of the formed object, the thermal stress causes a crack to result in forming failure.

  With respect to these problems, Patent Document 1 discloses a method of reducing thermal stress by using a shaping plate that supports a shaped object and releases heat to a shaping stage. According to the method of Patent Document 1, heat treatment is performed on the shaping plate to generate warpage deformation due to shrinkage stress, and the shaping plate is fixed on the shaping stage by actively utilizing the warpage deformation of the shaping plate. For this reason, it is difficult for stress to remain in a shaped object after completion of shaping. That is, it is supposed that the plate warpage deformation which occurs when the fixing of the shaping plate is released is reduced.

  Further, Patent Document 2 discloses a powder sinter layered manufacturing apparatus that makes the temperature of the surface of a thin layer of powder material uniform over the entire modeling region. According to Patent Document 2, since the entire thin layer of the powder material can be sintered more uniformly when the thin layer of the powder material is sintered, the sintered thin layer sintered near the boundary of the shaping region The difference in thermal stress is small even when the portion and the portion of the sintered thin layer sintered in the central portion are compared. The warp deformation of the shaped object formed by this is suppressed, and accurate formation can be performed.

  However, in the methods of Patent Literatures 1 and 2, the heat of the shaped object is dissipated only to the shaping stage. For this reason, when the number of laminations of the hardened layer which forms a modeling thing increases, the heat of a hardening layer becomes difficult to be radiated to the upper layer, and temperature distribution in a modeling thing becomes large. As a result, there is a problem to be solved, such as warping and deformation of a shaped object due to heat shrinkage after processing, to reduce processing accuracy.

  The present invention has been made in view of the above problems, and its object is to efficiently cool a three-dimensional object formed by laminating a cured layer, thereby enabling formation which is less likely to cause warpage deformation. To provide an additive manufacturing apparatus.

  The layered manufacturing apparatus of the present invention comprises a forming unit having a forming surface for forming a three-dimensional structure by laminating a hardened layer, a supplying unit for supplying a predetermined material to the forming surface, and a predetermined one of the supplied materials. A curing means for curing the region as the hardened layer, and a temperature control means provided on the material so as to be insertable into and removable from the material and controlling the temperature of the hardened layer by inserting the material into the material. Have.

  According to the lamination molding method of the present invention, a predetermined material is supplied to a forming surface on which a hardened layer is laminated to form a three-dimensional object, and a predetermined region of the supplied material is hardened to form the hardened layer, The temperature control means provided so as to be insertable into and removable from the material along the shaped surface is inserted into the material to control the temperature of the hardened layer.

  According to the present invention, by efficiently cooling a three-dimensional structure formed by laminating a cured layer, it is possible to provide a layered manufacturing apparatus that enables modeling with less occurrence of warpage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the embodiments described below are technically preferable limitations for carrying out the present invention, but the scope of the invention is not limited to the following.

And curing means 13 for curing predetermined regions of the material to form the cured layer. Furthermore, it has a temperature control means 14 provided so as to be insertable into and removable from the material along the modeling surface 11 a and controlling the temperature of the hardened layer by inserting into the material.

  According to the layered modeling apparatus 1, the heat of the three-dimensional model is not only dissipated to the modeling means 11 via the modeling surface 11a in contact with the model, but is also dissipated to the temperature control means 14 from the surface of the model Ru. Thereby, even when the number of laminated layers of the hardened layer forming the shaped object is increased, the heat of the upper layer is also dissipated to the temperature control means 14 from the surface of the shaped object, so the heat of the shaped object is dissipated efficiently. The temperature distribution in the object can be reduced. As a result, warpage of the three-dimensional structure due to heat is suppressed.

As a method of heating the material 101 and sintering or melt-hardening it to form a hardened layer, the material 101 may be irradiated with an electron beam to supply energy 115.

  The temperature control rod 108 is detachably provided to the material 101 along the modeling area 117 (modeling surface), and inserted into the material 101 to control the temperature of the material 101 and the hardened layer. The outer periphery of the temperature control rod 108 may be made of a material such as copper or a metal having a good thermal conductivity such as aluminum or stainless steel, but is not limited thereto. Further, stainless steel is preferable from the viewpoint of heat resistance and corrosion resistance in order to withstand the temperature of the molding area 117 at the time of molding, but the invention is not limited thereto.

  The shape of the temperature control rod 108 is cylindrical, and its cross-sectional shape can be any polygon such as a circle, an ellipse, or a tetragon. In particular, when the temperature control rod 108 is inserted by rotating the temperature control rod 108 into the material 101 of the shaping area 117, it is desirable that the cross-sectional shape be circular.

  FIG. 3C shows a configuration in which the temperature control rod 108 incorporates a temperature sensor 123 for measuring the temperature of the material 101. A thermocouple may be used for the temperature sensor 123. The temperature of the material 101 measured by the temperature sensor 123 can be sent to a control unit 114 described later via the temperature control unit 112 or the like. Based on the temperature of the material 101 measured by the temperature sensor 123, the control unit 114 can adjust irradiation conditions such as an irradiation pattern, an output, and a scanning speed of a laser beam irradiated to the material 101.

It is desirable to form a layer.

  The temperature control rod guide 109 holds the temperature control rod 108. The temperature control rod guide 109 allows the temperature control rod 108 to be inserted into the shaping area 117 with a constant orientation. Although a metal such as stainless steel can be used for the temperature control rod guide 109, it is not limited thereto.

  The temperature control rod guide 109 is attached to the movable wall 107. The temperature control rod guide 109 can adjust the position at which the temperature control rod 108 is inserted into the shaping area 117 by the movement of the movable wall 107. The elevation operation control unit 113 can move the movable wall 107 in conjunction with the movement of the modeling stage 103. The movement of the modeling stage 103 and the movable wall 107 is controlled by the elevation operation control unit 113 in accordance with the modeling process.

In FIG. 4, the feed mechanism 110 has gears in order to obtain a motive force for sending the temperature control rod 108 into the shaping area 117. Various metal materials can be used as the material of the feeding mechanism 110. In particular, in consideration of wear and the like, it is desirable to use a material harder than the temperature control rod 108. The operation of the feed mechanism 110 is controlled by the feed mechanism control unit 111.

  FIG. 5 is a view showing the configuration of another feed mechanism of the temperature control rod 108 of the layered manufacturing apparatus of the present embodiment. Another feeding mechanism of the temperature control rod 108 uses the rotating belt 119 and the rotating shaft 120 to insert the temperature control rod 108 into the shaping area 117 while rotating it. A toothed belt or the like can be used as the rotating belt 119. The rotation shaft 120 is operation controlled by the feed mechanism control unit 111. The temperature control rod 108 can be inserted into the shaping area 117 by moving the rotation shaft 120 in the insertion direction of the temperature control rod 108 while rotating the rotation shaft 120.

  A plurality of temperature control rods 108 may be disposed, and by disposing a plurality of movable walls 107, a plurality of temperature control rods 108 can be inserted into the modeling area 117 from different directions.

  The control unit 114 forms the modeling object 103, the material chamber 106, the supply cylinder 116, the material curing unit 104, the squeegee 105, the feeding mechanism control unit 111, the temperature control unit 112, and the elevating control unit It connects to 113 and controls these operations to cooperate.

  The control unit 114 can be realized by operating an information processing apparatus such as a server according to a program. Among the operations according to this program, the operation relating to additive manufacturing is set based on three-dimensional CAD data of the object. That is, the control unit 114 can control the formation of the three-dimensional object based on the three-dimensional CAD data.

  6A to 6D are diagrams for explaining the shaping method by the layered shaping apparatus 100 of the present embodiment.

  FIG. 6A shows an initial stage of formation of the three-dimensional structure 102. First, the powder material 101 is spread over the modeling area 117 to form a material layer, and a predetermined portion of the material layer is irradiated with laser light to cure the material 101. When the formation of the material layer is completed, the material 101 is spread again in the formation area 117 to form a new material layer, and a predetermined portion of the new material layer is irradiated with laser light to cure the material 101, and the lower layer is hardened. Integrate with By repeating this, the three-dimensional object 102 is formed.

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

  FIG. 6B shows a state in which the modeling stage 103 has been lowered to the position where the additive manufacturing proceeds and the temperature control rod 108 is inserted into the material 101. The position where the temperature control rod 108 is inserted can be set in the control unit 114 in advance. When the modeling stage 103 reaches a predetermined position, the control unit 114 temporarily interrupts modeling, and sends an instruction to the feed mechanism control unit 111 to insert the temperature control rod 108. When receiving this instruction, the feed mechanism control unit 111 operates the feed mechanism 110 to insert the temperature control rod 108.

  FIG. 6C shows that the insertion of the temperature control rod 108 into the material 101 is complete. At this time, according to the arrangement of the three-dimensional object 102, the insertion amount of the temperature control rod 108 may be set in advance so that the temperature control rod 108 does not collide with the three-dimensional object 102. it can.

  After the temperature control rod 108 is inserted, the temperature in the material layer is detected by the temperature sensor 123 disposed in the temperature control rod 108, and the irradiation pattern of the laser light is detected based on the detected temperature at the time of forming the next material layer. And irradiation conditions can be changed. Thereby, the temperature in the material layer can be made uniform. Further, by controlling the current supplied to 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 may be circulated when the material layer needs to be cooled based on the detected temperature, and may be stopped when the cooling is unnecessary. it can. Furthermore, by inserting the temperature control rod 108 at a position where the temperature tends to rise based on the detected temperature and circulating the refrigerant, the temperature in the material layer can be made uniform.

  FIG. 6D shows a state in which the three-dimensional structure 102 is completed by advancing the formation 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 lifted and lowered in accordance with the lifting and lowering of the molding stage 103 accompanying the stacking. Thereby, the positional relationship between the temperature control rod 108 and the three-dimensional structure 102 can be kept constant.

  After shaping is completed, the temperature control rod 108 is removed from the shaping area 117. The temperature control rod 108 can be removed from the modeling area 117 when the temperature control rod 108 is no longer needed even during the modeling. Further, the removed temperature control rod 108 can be inserted into a material layer different from the removed material layer, for example, a material layer laminated after the removed material layer.

  According to the layered manufacturing apparatus 100 of the present embodiment, the heat of the three-dimensional structure is not only dissipated to the modeling stage 103 via the modeling area 117 in contact with the modeling object, but also the temperature control rod 108 from the surface of the modeling object. It also dissipates heat. Thereby, even when the number of laminated layers of the hardened layer forming the shaped object is increased, the heat of the upper layer is also dissipated from the surface of the shaped object to the temperature control rod 108, so the heat of the shaped object is efficiently dissipated. The temperature distribution in the object can be reduced. As a result, warpage of the shaped article due to heat is suppressed.

  As described above, according to the present embodiment, it is possible to provide a layered manufacturing apparatus that enables modeling that is less likely to cause warpage deformation by efficiently cooling a three-dimensional structure formed by laminating a hardened layer. it can.
