  Hereinafter, the manufacturing method of the molded object which concerns on embodiment of this invention is demonstrated, referring a figure. In all the drawings below, the dimensions and ratios of the constituent elements are appropriately changed in order to make the drawings easy to see.

[First Embodiment]
FIG. 1 is a schematic diagram illustrating an example of a manufacturing apparatus 100 used for carrying out the method for manufacturing a molded body according to the first embodiment.

  The manufacturing apparatus 100 includes a light source unit 10 that irradiates light L, a holding unit 20 that holds the molded body 1, and a control unit (not shown) that controls the operation of the light source unit 10 and the holding unit 20. ing. The manufacturing apparatus 100 irradiates the light L to an uncured photocurable resin 2 (hereinafter, abbreviated as “resin 2”) supplied to the surface of the molded body 1, and has a desired three-dimensional shape. It is a device for manufacturing the body.

  As the molding 1, various materials such as a resin material and an inorganic material can be used. The shape of the molded body 1 is not limited to a flat surface on which the resin 2 is disposed, and may have a curved surface. The molded body 1 may be a molded body formed in advance using an arbitrary modeling method, in addition to members having various shapes such as a plate shape, a columnar shape, and a spherical shape. Moreover, in order to make the resin 2 adhere firmly when the resin 2 is cured, it may be subjected to a surface treatment such as roughening or resin coating.

  In the present embodiment, description will be made assuming that a glass slide glass is used as the molded body 1.

  As the resin 2, a liquid photo-curing resin in an uncured state can be used. As such a resin, a conventionally known resin can be used, and examples thereof include an epoxy resin, an acrylic resin, and a silicone resin.

  The resin 2 may contain a photopolymerization initiator and a filler. For example, when silver fine particles are contained as a filler, it becomes a photocurable silver paste and can be used for forming a wiring structure.

  In the present embodiment, an explanation will be given assuming that an ultraviolet curable resin is used as the resin 2.

  The light source unit 10 includes a laser light source 11, a shutter 12, an objective lens 13, an optical fiber 14, a first support unit 15, and a second support unit 16.

  The laser light source 11 emits a laser beam LB having a wavelength for starting the photopolymerization of the resin 2. For example, when the resin 2 is an ultraviolet curable resin, an apparatus that emits an ultraviolet laser can be used as the laser light source 11. In the present embodiment, the laser light source 11 will be described as irradiating an ultraviolet laser.

  The shutter 12 blocks or allows the laser light LB emitted from the laser light source 11 to pass through. Thereby, in the location which does not require light irradiation, light irradiation can be stopped without turning off the laser light source 11. The shutter 12 performs an opening / closing operation according to an instruction from a control unit (not shown), for example.

  The objective lens 13 condenses the laser light LB emitted from the laser light source 11. Thereby, the laser beam LB can be efficiently introduced into one end of the optical fiber 14.

  The optical fiber 14 guides the laser beam LB incident from one end side and emits it from the other end side. As the optical fiber 14, a generally known optical fiber can be used, and the diameter of the core can be appropriately selected according to the resolution when the molded body to be manufactured is formed. For example, a thick core optical fiber can be used when rough molding is possible, such as a molded body with few surface irregularities, and a thin core optical fiber is used when molding a portion that requires fine modeling processing. Can be used.

  One end of the optical fiber 14 is an entrance for the laser beam LB via the objective lens 13. The other end corresponds to the light exit port in the present invention.

  One end of the optical fiber 14 is supported by the first support 15 and the other end is supported by the second support 16.

  The first support portion 15 includes a clamp 151, a strain relief 152, and a triaxial stage 153. The clamp 151 and the strain relief 152 support one end of the optical fiber 14. The triaxial stage 153 can move the spatial position of one end of the optical fiber 14 three-dimensionally. Thereby, alignment with the condensing position of the objective lens 13 and the position of the one end of the optical fiber 14 becomes easy.

  The second support portion 16 includes a clamp 161 and a strain relief 162. The clamp 161 and the strain relief 162 support the other end of the optical fiber 14. The second support portion 16 is attached to a base (not shown) or the like, and fixes the spatial position of the other end of the optical fiber 14.

  If the distance from the clamp 161 to the other end of the optical fiber 14 is long, the optical fiber 14 is likely to be bent, and the light irradiation position is changed. Therefore, the position where the second support portion 16 supports the optical fiber 14 is preferably a position where the second support portion 16 does not touch the resin 2 and is as close to the other end of the optical fiber 14 as possible.

  The holding unit 20 includes a mounting table 21, an xyz axis automatic stage 22, and a z axis stage 23.

  The mounting table 21 mounts the molded body 1.

  The xyz axis automatic stage 22 automatically moves the mounting table 21 in the x, y, and z axis directions during manufacture of the molded body, for example, according to an instruction from a control unit (not shown). As a result, the xyz-axis automatic stage 22 changes the relative position between the other end of the optical fiber 14 and the molded body 1 and the resin 2 supplied onto the molded body 1.

  The z-axis stage 23 is used, for example, when setting the initial state of the height position of the molded body 1.

  FIG. 2 is a process diagram illustrating a method for producing a molded body according to the present embodiment. In the drawing, the core of the optical fiber 14 is denoted by reference numeral 141, and the cladding is denoted by reference numeral 142.

  First, as shown in FIG. 2A, the other end 14a of the optical fiber 14 is brought into contact with an uncured photocurable resin 2A disposed at a predetermined position, and the resin 2 is attached to the other end 14a. Thereafter, with the resin 2 attached to the other end 14a, the optical fiber 14 is relatively moved to the molded body 1, and the resin 2 attached to the other end 14a is attached to the surface 1a of the molded body 1 and supplied ( Supplying step).

  Next, as shown in FIG. 2B, the distance H between the light exit port 141a, which is the end of the core 141, and the surface 1a is controlled to a desired value (control step).

  Next, the light L is irradiated from the light emission port 141a to the resin 2 in a state where the light emission port 141a and the resin 2 supplied to the surface of the molded body 1 are in contact (step of performing light irradiation). As a result, the resin 2 between the light exit port 141a and the surface 1a is cured. The height of the cured product of the resin 2 is equal to the separation distance H. That is, the height of the cured product of the resin 2 can be controlled by mechanically controlling the separation distance H. Therefore, it is not necessary to control the thickness of the uncured photocurable resin as in the conventional method, and the height of the cured product of the resin 2 can be easily controlled.

  Next, as shown in FIG. 2C, the optical fiber 14 is relatively moved in a direction intersecting the light irradiation direction (in the drawing, the surface direction of the surface 1a). The cured product of the resin 2 is generated in a state where it adheres to the light exit port 141a, but the cured product and the light exit port 141a are easily separated by moving the optical fiber 14 in a direction crossing the light irradiation direction. . Thereafter, the remaining resin 2 is appropriately washed with a solvent. As a result, the cylindrical molded body 3 whose height is controlled to the separation distance H can be obtained without breaking.

  Further, in the droplet of the resin 2 shown in FIG. 2B, the optical fiber 14 is relatively moved two-dimensionally in the surface direction of the surface 1a of the molded body 1, thereby spreading in the surface direction of the surface 1a. The molded body 3 is obtained.

At this time, when the amount of liquid droplets is large, it is possible to produce a molded body in which a plurality of layers are laminated by controlling the separation distance H and repeatedly forming the molded body on the layered molded body 3. it can.
When the amount of droplets is small, the same operation as that shown in FIGS. 2A, 2B, and 2C is performed on the layered molded body 3 to produce a molded body in which a plurality of layers are laminated. be able to.

  When the core diameter of the optical fiber 14 is large or the affinity between the light exit port 141a and the resin 2 is high, the peel strength between the light exit port 141a and the cured product of the resin 2 is a cured product of the resin 2. And the peel strength between the surface 1a and the surface 1a. In such a case, even if the optical fiber 14 is moved, the cured product of the resin 2 may be separated from the surface 1a before the light exit port 141a and the cured product of the resin 2 are separated, and may be damaged.

  In such a case, it is preferable to perform a surface treatment for reducing the surface energy of the light exit port in advance, and to lower the peel strength between the light exit port 141a and the cured product of the resin 2 as compared with the case where it is not treated. As such a process, for example, a process of fluorine-coating the surface of the light exit port 141a can be cited.

  Thereafter, as shown in FIG. 2D, by repeating the steps of FIGS. 2A, 2B, and 2C on the surface 1a, the molded body 3 can be formed at an arbitrary location on the surface 1a. That is, the molded body 3 can be formed at a position different from the arrangement position of the droplets of the resin 2 shown in FIG. Therefore, it is possible to manufacture a desired molded body by supplying a small amount of the resin 2 to a place where the molded body needs to be formed.

  The shape of the molded body 3 can be controlled by changing the diameter of the core 141 of the optical fiber 14, the output of the laser light source 11, the irradiation time of the light L, etc. in addition to the above-mentioned separation distance H. For example, when the output (emitted light intensity) of the laser light source 11 is increased, the emitted light L easily spreads in the emitting direction, and as a result, a truncated cone shaped molded body is obtained.

  According to the method for producing a molded body as described above, the thickness control of the cured product in the optical modeling method can be performed more simply.

[Second Embodiment]
FIG. 3 is a process diagram illustrating a method for producing a molded body according to the second embodiment. In this embodiment, it demonstrates as using the manufacturing apparatus 100 shown in 1st Embodiment.

  First, as shown to Fig.3 (a), the resin 2 is apply | coated to the surface of the to-be-molded body 1, and the coating film of the resin 2 is formed (supply process). As a method for forming the coating film, a known printing method such as a screen printing method, a spin coating method, an ink jet printing method, or a bar coating method can be employed.

  Next, as shown in FIG. 3B, the separation distance H between the light exit port 141a that is the end of the core 141 and the surface 1a is controlled to a desired value (control step).

  Next, the light L is irradiated from the light emission port 141a to the resin 2 in a state where the light emission port 141a and the resin 2 supplied to the surface of the molded body 1 are in contact (step of performing light irradiation).

  Next, as shown in FIG. 3C, the optical fiber 14 is relatively moved in a direction intersecting the light irradiation direction (in the drawing, the surface direction of the surface 1a). At that time, as shown in the figure, it is also possible to perform light irradiation continuously while relatively moving the molded body 1 and the light emission port 141a. Thereby, the cylindrical cured product is continuously formed while contacting in the moving direction of the light emission port 141a, and as a result, the band-shaped molded body 4 whose height is controlled to the separation distance H is obtained.

  Similarly to the first embodiment, the two-dimensional relative movement of the optical fiber 14 in the plane direction of the surface 1a of the molded body 1 allows the layered molded body 4 to spread in the plane direction of the surface 1a, or a plurality of layers. Can be produced.

  Also by the manufacturing method of the above-mentioned molded object, thickness control of the hardened | cured material in an optical modeling method can be performed more simply.

[Third Embodiment]
FIG. 4 is a process diagram illustrating a method for producing a molded body according to the third embodiment. In this embodiment, it demonstrates as using the manufacturing apparatus 100 shown in 1st Embodiment.

  First, as shown in FIG. 4A, the resin 2 is stored in the storage unit 50, and the molded body 1 mounted on the mounting table 51 is immersed (supplied) in the stored resin 2. Process).

  Next, the separation distance H between the light exit port 141a that is the end of the core 141 and the surface 1a is controlled to a desired value (control step). Next, the light L is irradiated from the light emission port 141a to the resin 2 in a state where the light emission port 141a and the resin 2 supplied to the surface of the molded body 1 are in contact (step of performing light irradiation).

  Next, as shown in FIG. 4B, the optical fiber 14 is moved in a direction crossing the light irradiation direction (in the drawing, the surface direction of the surface 1a). At that time, as shown in the figure, the band-shaped molded body 5 whose height is controlled to the separation distance H by continuously irradiating light while relatively moving the molded body 1 and the light emission port 141a, or A layered molded body 5 is obtained.

  Similarly to the first embodiment, the two-dimensional relative movement of the optical fiber 14 in the plane direction of the surface 1a of the molded body 1 allows the layered molded body 5 extending in the plane direction of the surface 1a or a plurality of layers. Can be produced.

  According to the method for producing a molded body as described above, the thickness control of the cured product in the optical modeling method can be performed more simply.

[Fourth Embodiment]
FIG. 5 is a process diagram illustrating a method for producing a molded body according to the fourth embodiment.

  A molded body (molded body) 6 shown in FIG. 5A is a molded body produced by using, for example, an optical modeling method. The molded body 6 produced using the optical modeling method is formed by laminating a plurality of layers in the height direction, but a step (indicated by reference numeral 6x in the figure) is generated at the end of the layer, and it is difficult to form a smooth surface. . This is due to the difficulty in forming a surface that is inclined with respect to the stacking direction in the normal stereolithography because the light irradiation direction coincides with the stacking direction of the plurality of layers.

  For such a molded body 6, first, as shown in FIG. 5A, the resin 2 adhered to the end of the optical fiber 14 is applied to the step portion 6 x in the same manner as in the manufacturing method of the first embodiment. Supply. At that time, the posture of the optical fiber 14 is controlled so that the light irradiation direction from the optical fiber 14 is inclined inward of the molded body 6 with respect to the stacking direction.

  Next, the separation distance between the light exit port 141a and the surface of the molded body 6 is controlled to a desired value (control step). The control of the separation distance may be performed based on an actual measurement value of the molded body 6, for example, based on an approximate value based on CAD data used when the molded body 6 is manufactured.

Next, the light L is irradiated from the light emission port 141a to the resin 2 in a state where the light emission port 141a and the resin 2 supplied to the surface of the molded body 1 are in contact (step of performing light irradiation).
Thereby, as shown in FIG.5 (b), the level | step difference part 6x can be filled with the new hardened | cured material 7, and the level | step difference of the surface of a molded object can be reduced.

  Moreover, according to the manufacturing method of this embodiment, what has a various shape can be employ | adopted as a to-be-molded body, and it becomes possible to add a structure further to the to-be-molded body of a predetermined shape. For example, it is possible to perform stepwise molding such as forming the rough shape of the target molded body by stereolithography and then forming the fine shape of the target molded body using the manufacturing method of this embodiment. It becomes. When such stepwise forming is performed, the operation time can be shortened as compared with the case where all operations are performed with a processing accuracy for forming a fine shape.

[Fifth Embodiment]
FIG. 6 is a schematic diagram showing an example of a manufacturing apparatus 200 used for carrying out the method for manufacturing a molded body according to the fifth embodiment. FIG. 6A is a diagram illustrating an overall configuration of the manufacturing apparatus 200, and corresponds to FIG. 1 of the first embodiment. FIG. 6B is an enlarged view showing the other end side of the optical fiber 14 in the manufacturing apparatus 200.

  As shown in FIG. 6A, the manufacturing apparatus 200 supplies the light source 10 that irradiates the light L, the holding unit 20 that holds the molded body 1, and the supply of the resin 2 to the surface of the molded body 1. And a control unit (not shown) that controls the operation of the light source unit 10, the holding unit 20, and the supply unit 30. The manufacturing apparatus 200 differs from the manufacturing apparatus 100 shown in the first embodiment in the configuration of the supply unit 30, and the other configurations are common.

  The supply unit 30 includes a tank 31 that stores the resin 2, a pump 32 that flows the resin 2, and a pipe 33 through which the resin 2 flows.

  The pump 32 is disposed in the path of the pipe 33 and causes a predetermined amount of the resin 2 to flow into the pipe 33 according to an instruction from the control unit.

  One end of the pipe 33 is connected to the tank 31, and the other end is disposed on the surface of the molded body 1. The optical fiber 14 is inserted into the pipe 33 between the pump 32 and the other end. The other end of the optical fiber 14 is exposed from the other end of the pipe 33.

  Specifically, as shown in FIG. 6B, the other end 14 a of the optical fiber protrudes outside the other end 33 a of the pipe 33. The resin 2 flowing in the pipe 33 is discharged from the other end 33a and supplied to the surface 1a of the molded body 1. The supplied resin 2 is supplied to the surface 1 a while being in contact with the other end 14 a of the optical fiber 14.

  When the manufacturing apparatus 200 having such a configuration is used, for example, the resin 2 is continuously supplied to the surface 1a of the molded body 1, and the separation distance between the light emission port 141a and the surface of the molded body 6 is set to a desired value. The height is separated by irradiating the resin 2 with the light L from the light exit port 141a in a state where the light exit port 141a is in contact with the resin 2 supplied to the surface of the molded body 1. The molded body 8 controlled to the distance H can be easily manufactured.

  In addition, after controlling the separation distance of the light emission port 141a and the surface of the molded object 6, it is good also as performing light irradiation, starting supply of the resin 2 from the supply part 30 to the surface 1a.

  According to the method for producing a molded body as described above, the thickness control of the cured product in the optical modeling method can be performed more simply.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to such examples. Various shapes, combinations, and the like of the constituent members shown in the above-described examples are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

  For example, it is good also as manufacturing a molded object using the optical fiber which provided the lens which has a positive refractive power in the light exit port in the light exit port 141a instead of the optical fiber 14 mentioned above. By providing the lens, the resin 2 can be cured at the focal position of the lens away from the light exit port 141a. Therefore, the cured product is difficult to adhere to the light exit port 141a, and damage to the molded body can be suppressed.

  In the second embodiment, the separation distance between the light exit port 141a and the surface 1a is controlled after the coating film of the resin 2 is formed. However, the separation distance between the light exit port 141a and the surface 1a is controlled in advance. After the control, the resin 2 may be supplied so as to come into contact with the light emission port 141a.

(Influence of light irradiation conditions)
A photocurable resin was placed on the slide glass, and light irradiation was performed in a state where the tip of the optical fiber was in contact with the photocurable resin to produce a cylindrical molded body. At that time, as the light irradiation conditions, the light irradiation time and the output of the laser light source were changed, and the diameter of the obtained molded body was measured. The diameter of the compact was determined from a micrograph taken with a scanning electron microscope.

FIG. 8 shows a micrograph of the obtained molded body.
8A to 8C were manufactured by controlling the separation distance between the slide glass and the light emission port to 10 μm.
8D, the first layer is formed by controlling the separation distance between the slide glass and the light emission port to 10 μm, and then the separation distance between the slide glass and the light emission port is separated by 2 μm. Then, the height of each layer was controlled to laminate a plurality of layers.

As shown in FIGS. 8A to 8C, it was possible to draw characters using only the photocurable resin attached to the tip of the optical fiber at an arbitrary position on the slide glass.
Further, as shown in FIG. 8 (d), a pyramid-shaped solid body in which a plurality of layers were laminated could be formed.

  From the above results, it was found that the present invention is useful.
