THREE-DIMENSIONAL MODELING DEVICE, OBJECT, AND METHOD FOR PRODUCING A SUBJECT
background
This invention relates to a three-dimensional modeling apparatus that forms a three-dimensional article from a photo-curing material, an article formed with this device, and a method of manufacturing an article.
In the past, a modeling apparatus which forms a three-dimensional object has been known as a rapid prototyping apparatus widely used for commercial purposes. Generally, a three-dimensional modeling apparatus forms an object layer by layer in accordance with shape data for each predetermined thickness of a target which is to be modeled, ie with shape data for each layer.
As one of the main methods for the three-dimensional modeling apparatus, a stereolithography is exemplified, in which a photocuring resin is selectively irradiated with a laser light sc so that desired parts of the resin are cured and peeled off to thereby form an article.
For example, stereolithography includes an open space method as well as a bounding surface method. In the open-area method, the liquid surface of the photocurable resin is exposed to the air, the laser light being focused on an interface between the air and the liquid surface so that the drawing is carried out. In the open space method, there is a problem that the precision in coating the resin (the accuracy of the thickness for each rail or the accuracy of the surface state of the resin for each layer) depends on the surface area of the liquid surface.
In contrast, in the confinement surface method, the liquid surface of the light-curing film is confined, for example, by a flat glass surface, with the laser being focused through the G_as onto an interface between the liquid surface and the glass surface, so that a Drawing is executed.
Japanese Patent Application Laid-open No. 2009-137048 (hereinafter referred to as Patent Document 1) discloses a stereolithography apparatus using the confinement surface method. This stereolithography apparatus includes a position restricting mechanism for preventing the glass from deflecting and keeping the glass flat (see, for example, numeral [0077] and the like in the specification, and Figs. 7 to 10 of the pin document 1).
Summary
In a fence area using the glass as in Fatendocumer.t 1, it is necessary that the cured resin be peeled from the glass after the modeling is completed for each layer. However, as a range to be modeled for each layer becomes larger, the force required for peeling also increases. In some cases, it may break the object or separate the object from its seat (stage on which the object is to be piled up).
Further, when the area to be modeled for each layer becomes larger as described above, the glass may be overstressed or warped due to a contracting force of the cured resin and deflected to the resin. This affects the evenness of the article for each layer. At this point, in the above-mentioned patent document 1, only the deflection of the glass is considered, and no countermeasures are taken against the phenomenon that the glass is warped opposite to the direction of deflection.
As the viscosity of the photocurable resin increases, eir. Pressure greater that the resin exerts on the seat or the glass surface. As a result, the glass surface is stressed, causing another problem, 3 * · * ·· · ** 9 # * * · · «9 * ··« «9 * 99« · »I ·» 9 ····· * I I. «
For each layer, the thickness of the resin for each layer can not be fired so that it has a predetermined thickness.
In view of the above-mentioned circumstances, there is a need to provide a three-dimensional modeling apparatus that enables a hardened layer of the material to be separated cleanly from a confining body defining an upper surface of a material to form an article, and which enables the flatness of each layer to be improved or the thickness of each layer to be controlled with great accuracy. Further, there is a need to provide an article that can be formed with this device as well as a method for making an article.
In accordance with disclosure, one is provided which includes a delivery nozzle, a movement mechanism. an embodiment of the present three-dimensional modeling stage, a confining body, a
Irradiation unit and a
The containment body comprises a surface having a linear region along a first direction, arranged to face the stage such that the linear region of the surface is closest to the stage.
The feed nozzle is adapted to supply a material, which can be cured with the energy of energy radiation, into a slot area, which is an area between the stage and the linear area.
The irradiation unit is configured to irradiate the material, which is supplied from the feed nozzle into the slit area, through the confinement body with the energy radiation.
The moving mechanism is configured to move the stage relative to the confining body along a second direction different from the first direction to form a hardened layer of the material for a layer using the energy ray. Furthermore, so the movement mechanism is limb body and the stage Aufschiebtriehtung moved to layer material. aurgeoaut that '* dr " relative to each other along one of the hardened layers of the
The confinement body is arranged so that the linear area of the area is closest to the stage. Thus, the material is irradiated with the energy radiation and cured in the slot area or in an area in its vicinity. This means that the material is essentially cured in the slot area between the stage and the linear area. Downstream of the confining body, the two are relatively moved by the moving mechanism so that the surface of the confining body is separated from the stage. Thus, the cured layer of the material can be cleanly detached from the limb body.
Furthermore, the slot area is not formed by a wide and flat area but by the linear area of the containment body. As just described, so that the material can be easily separated from the limb body. Even if the contracting force is applied to the containment body when the material has cured, the containment body is prevented from being overstressed or deformed. Thus, it is possible to improve the planarity of each cured layer and to control the thickness of each cured layer with high accuracy.
The linear region can be one-dimensional or two-dimensional. When the linear region is two-dimensional, the linear region may be a plane surface or a curved surface. If it is the linear. In fact, if the area is actually a curved surface, no problem occurs as long as the linear region has such an area that the top surface of the cured layer of the article can retain the desired accuracy of the planar surface.
The confining body may be formed to have the Ferm of a cylinder. In this case, the surface having the linear region is formed on an outer circumferential surface of the confining body, which has the shape of a cylinder 5. ··· «· · owns. In this case, an axial direction * of the cylinder body substantially corresponds to the first direction. A part of the outer circumferential surface along this axis direction represents the linear bererch. When the confinement body is formed in the shape of a cylinder, the function of the confining body can be provided with a simple shape. Further, when the confining body is in the form of a cylinder, the confining body can move in a state where the material is fed into the slot area when the moving mechanism moves the confining body and the stage relative to each other due to the frictional force between the confining body and the material rotate and move around the axis.
The irradiation unit may be disposed within the egg border bank formed in the shape of a cylinder. Bamil is given an advantage when the one-person body is designed to have the shape of a cylinder. In comparison with a family in which the irradiation unit is disposed a.superior to the i.by body, the three-dimensional mode-splitting device can further be made smaller. will be another storage
The three-dimensional modeling apparatus may further comprise a plurality of guide rollers which are formed so as to hold the restriction body so that it can be displaced. Dami · 1 superfluous.
The three-dimensional mode parts of the at least one antenna may be further configured to drive the drive roller of the many guide rollers of the ancillary part. This allows n to rotate. For example, when the feed nozzle supplies the material to the confining body, the driving member displaces the oil body, causing the material to enter the body
Sc.il-Lzbw.eict can be supplied. Alternatively, if excess material on a part of the outer
The outer surface of the limb adheres to the drive part, the Einf körper fenzkörper m so rotation that between the area of an unused. Area where the excess Ma < -e__al does not adhere and the stage is the slot area 6 · · · · · T ·· · · * * * * is trained.
The Eir.grenzkörper kar.r. be constructed so that it has the shape of a plate having a Ooerfiäche, which uir. is a curved surface. Thus, it can be suppressed that the three-dimensional modeling apparatus becomes larger, at the same time, the area of the linear area, which can be regarded as a flat area, can be increased.
The containment body may be constructed to be part of a cylinder body. In the case where the confining body is formed by a cylinder body, the irradiation unit is provided inside the cylinder body, thereby limiting the length of the optical path of the energy ray. As is the case with the present disclosure, the restriction of the length of the optical path of the energy radiation can be canceled when using a confining body having a Ferm obtained by cutting out a cylindrical body.
The moving mechanism may be seeded to move the confining body and the stage relative to each other along a direction having a vertical component. As a result, the surplus material can flow downwardly from the article due to its own weight, thereby reliably eliminating the excess material, thus realizing modeling with high accuracy.
The three-dimensional modeling device can further a
Cleaning nozzle, which is adapted to the cleaning of the object, which is formed on the stage. The cleaning agent is dispensed by the Rein_gungsdü ^ e z_un object. On the other hand, when the article is cleaned using the cleaning agent, the cleaning agent flows down from the article, causing the article, i. the upper surface of the hardened rail, can be cleaned. This can be the

The supply nozzle may have a plurality wherein the plurality of supply nozzles of supply nozzles, is designed so that it emits so different materials. In particular, when the moving mechanism moves the confinement body or the stage along a direction having a vertical component, it becomes easy to remove the excess material, thus making it easy to remove the excess material for each layer. In addition, it becomes easy to form an article having different kinds of materials for each layer.
The feed nozzle may include a nozzle, which is a slot coating nozzle. Thus, it is possible to control the thickness of the cured layer for a layer with high accuracy.
The feeding nozzle kar.r. be constructed so that it supplies a material that is thixotropic. Thus, for example, an object can be formed, which has an overhanging part.
The confining body and the supply nozzle may have a plurality of confining bodies and a plurality of supply nozzles, with one pair of each of the plurality of confining bodies and each of the plural supply nozzles constituting one set. In this case, it suffices that the plurality of sets of confining bodies and feeding nozzles are arranged along the second direction in which the moving mechanism moves the stage. As a result, different types of material can be verwenaet for the formation of an object.
The irradiation unit may emit the energy radiation such that a main body, which is the target to be modeled, and an anchor pattern disposed in at least one edge portion of the main body of the object are formed. Thus, an edge portion of the main body of the object can be formed with high accuracy.
The irradiation unit may provide a generator source configured to generate the energy radiation and a detector configured to scan the intensity distribution of the energy radiation generated by the generator cell. In this case, the 8 Φ φ φ · «* 14 * * * * φ φ · · · * · · * * * * * φ φ φ * * * * * * ΦΦ φφ 4 I * φ φ ι ι three-dimensional modeling further. a control mechanism configured to control the relative positions of the confining body and the irradiation unit based on the intensity distribution of the energy radiation as it is scanned by the detector. Thus, the position of the Eir.grenzkörpers can be controlled accordingly, whereby the thickness of the thin film of the material can be controlled with high accuracy.
The three-dimensional modeling apparatus may further comprise a rotating mechanism configured to rotate the stage about an axis along the stacking direction. This can be a scan with a
Energy radiation can be performed in a desired direction. Thereby, it can be prevented that, for example, a deformation (incidence or bulges) is formed in the article when the article is removed from the stage.
The three-dimensional modeling device may further comprise a protective thin film provided on the surface of the confining body. For example, when the sheet thin film is a thin film that can be removed, removal of this film can clean the surface of the bed. Alternatively, when the protective thin film has been previously formed on the surface of the confining body, for example, it is possible to perform the surface cleaning by simply cleaning or blown off with a gas.
The three-dimensional mode adjusting means may further comprise an irradiation mechanism and a control part. The irradiation mechanism is configured to emit a plurality of energy beams as energy radiation. The control part is configured to control the irradiation mechanism such that a time interval in which all of the many energy beams are radiated has a time interval in which at least two energy beams of the plurality of energy beams are radiated simultaneously. Thus, a wide area on the material 9 I ι «· · · ·» * * * # »* 4Φ * * * * * * * * 4 I *« 41 · «« · • t * I »* * ·« t · 4 · 4 (I 4 · I * * · * · »# * * 4) can be simultaneously subjected to an exposure process, whereby a time interval required for the modeling process can be shortened.
In accordance with another embodiment of the present disclosure, there is provided an article to be formed by a three-dimensional modeling apparatus, the three-dimensional modeling apparatus having a stage and a confining body having a surface including a linear portion along a first direction, wherein it is designed so that it faces the stage so that the linear area of the surface is closest to the stage. The article is formed by the following method.
A material that can be cured with the energy of energy radiation is fed into a slot area, which is an area between the stage and the linear area.
The material fed into the slot area is irradiated by the confining body with the energy beam.

The drum 10, which serves as a confining member, adjoins the height of an upper surface of a material supplied from a 2-feeding nozzle to the Mocellierbühre 15, as will be described later. The drum io is formed so as to have substantially the shape of a cylinder, for example, made of glass. The drum 10 has a through hole formed in the X-axis direction. In other words, the drum IC is formed to have the shape of a pipe. As will be described later, a support member 4 carrying an irradiation unit 30 is provided so as to pass through the through hole (the inside of the cylinder body) of the drum 10.
Instead of glass, the drum 10 can also be made of acrylic resin or other transparent resin. The material of the drum 10 is not necessarily limited to these materials. Any material may be used for the drum 10 as long as the material transmits the energy radiation emitted by the irradiation unit 30.
The inner diameter of the drum 10 is in the range of about 30 to 70 mm, wherein the wall thickness is about 2 mm. However, this area can be changed accordingly.
The modeling stage is supported by a raising / lowering mechanism 14 to raise and lower it. The modeling stage 15 and the raising / lowering mechanism 14 are arranged on a movable base 11.

The two guide rollers 5 and 6 hold the outer surface (surface) 10 a of the drum 10 from below. That is, the three guide rollers 5, 6 and 7 sandwich the wall of the drum 10 so as to hold the drum 10. As already described above, the guide rollers 5, 6 and 7 hold the drum 10 so that it does not have to be stored.
The guide rollers 5, 6 and 7 hold the drum 10 in a predetermined height position in the direction of the Z-axis so that a slot area S (see FIG. 6), which will be described later, between the stage and the outer circumferential surface 10a of the drum 10th is trained. This is done so that the upper surface of the modeling stage 15 faces a linear region Al along the direction of the X-axis (first direction), thereby forming the slit region S, the linear portion Al being the lowest part of the outer surface 10a of the drum 10 (the portion of the drum 10 closest to the stage). The linear region Al forms part of the outer surface 10a of the drum IC, which is an area that can be considered substantially flat.
The width of the linear region Ä.1 in the direction of the Y-axis (second direction) is irr. Range of 0.1 to 1 mm. Further, the dot diameter of the laser light emitted from the irradiation unit 30, as will be described later, is in the range of 1 to 100 μm. However, the width of the linear area Al and the dot diameter may vary depending on the size of the drum, the size of the drum

As shown in FIG. 3, of the three guide rollers 5, 6 and 7, for example, a guide roller 5 is arranged so that it is ground by a roller motor 8. As a result, the drum 10 is rotated by the guide roller. It should be noted that an embodiment may be used in which two or more of the guide rollers 5, 6 and 7 sc are arranged to be driven by a motor.
It should be noted that the arrangement of these three guide rollers 5, 6 and 7 is not limited to the arrangement in the embodiment of Fig, 1 and can be modified accordingly.
Between the side walls 2, a feed nozzle 26 is provided which is formed along the X-axis and the drum 10 Eir. under light-curing material R feeds. The feed nozzle 26 is disposed below the drum 10, for example, at a position spaced from the linear range Al, which is the lowermost portion of the drum 10. As the feeding nozzle 26, a nozzle having a plurality of openings (not shown) along the longitudinal direction thereof for discharging the photocurable material R may be used. Alternatively, as the feeding nozzle 26, there may be provided a slit coating nozzle having a slit provided in its longitudinal direction. The plurality of openings or the slot open to a side on which the drum 10 is arranged.
It should be noted that the feed nozzle 25, for example, with a pump, a line, a. On-off valve and the like (not shown) may be connected to feed into the feed nozzle 26, the light-curing material R.
As shown in FIG. 1, the three-dimensional modeling apparatus 100 has the raising / lowering mechanism (part of the moving mechanism) 14 which supports the modeling stage 15 and raises and lowers the modeling stage 15 toward the movable base 11. The raising / lowering mechanism 14 uses an arbor raising / lowering motor 19 to raise the modeling stage 15 and 16
to lower thereby a distance between the
Modeling stage 15 and the linear range AI of the drum 10 to control. The uppermost position of the modeling stage 15, which has been raised by the raising / lowering mechanism 14, is substantially set to a position in which the linear area A1 of the drum 10 is located. Although the modeling stage 15 is circular in the horizontal plane (in the X-Y plane), the shape is not limited to the shape of a circle. The shape may be a rectangular shape or any other shape. As the photocurable material R, an ultraviolet curing type resin is typically used.

On the rear side of the three-dimensional modeling device 100, two support posts 3 are provided, which rise from the 3asis 1. Between these two support posts 3, the support element 4 is provided. As already described above, the support member 4 is provided so as to pass through the inside of the drum 10. The irradiation unit 30 is disposed on the inside of the drum 10 and can be moved in the X-axis direction by an X-axis moving mechanism 60 provided on the support member 4. The X-axis movement mechanism 60 includes an X-axis moving motor 63 (see FIG. 3), a rail plate 62 having guide rails 62a and fixed on the support member 4, and a movable plate 61 attached to the rail plate 62 is that she can be moved.

The irradiation unit 30 is mounted on the movable plate 61 and has a laser light source 31, an objective lens holder 32 disposed immediately under the laser light source 31, an objective lens 34 (see FIGS. 2, 3 and the like) shown in FIG * * Μ * * * · m · · · · · · · · · · · · · · · · · · · · · «« * · «*« · «Ftft ftt
Objective lens holder 32 is held, and a mounting plate 33. The fixing plate 33 supports the laser light source 31 and the objective lens holder 32 and fixes them with respect to the movable plate 61.
The irradiation unit 30 limits the spot diameter of the laser beam emitted from the laser light source 31 through the objective lens 34, and focuses it through the wall of the drum 10 onto the Lichr-curing material R disposed in the shooting area S or under the light hardening material R disposed in the slit region S and in the vicinity of the slit region S. That is, the objective lens 34 is typically arranged on the optical axis so that the focal point of the laser light is at least equal to the photo-curing material R in the shooting region S.
The raising / lowering mechanism 14, the Y-axis 3-movement mechanism 70 and the X-axis

The host computer and the corresponding controllers include a central processing unit (CPU), a RAM (Random Access Memory), a ROM (Read Oniy Memory, etc.) and the like. Also included in the central control unit may be a Digital Signal Processor (DSP), a Programmable Logic Device (PLD) (eg a field programmable gate array, FPGA), a custom integrated circuit (Applicant Specific Integrated Circuit, ASIC) or the like. Although it is typical for the controllers to be wired together, at least one of these controllers may be wirelessly connected to a control system of the three-dimensional modeling apparatus ICC. All controllers can be designed in terms of hardware. (Operation of the three-dimensional modeling device) three-dimensional pointing to the above views

Now, a mode of modeling apparatus 100 described described type is built on. Fig. 4A of steps of the operation.
Fig. 4A shows a state in which the three-dimensional modeling apparatus 100 has been stopped and the moving base 11 is in a home position. Before the modeling is actually carried out, the thickness for a layer of the cured layer consisting of the photocurable resin R is set with the host computer. Then, for example, by putting the raising / lowering mechanism 14 into operation by means of the control for the lowering / lowering motor 51, the height position of the modeling stage 15 is adjusted, when the modeling stage 15 is brought into contact with the linear area Al , which is the lowest part of the drum 10, has been set as the origin for the Z-axis direction.
It should be noted that with respect to a position of the modeling stage 15 in the direction of the Y-axis at the time of setting the origin, it can be set accordingly.
When the origin is set, the modeling stage 15 for the given thickness is lowered from a layer of the photo-setting material R.
After the modeling stage 15 has been lowered, the modeling stage 15 is moved by the Y-axis moving mechanism 70 to a moulting pitch, which is a predetermined pitch, as shown in Fig. 4E. The modeling home position means a slope of the modeling stage 15 in a direction along the Y-axis so that the slit area S is formed between the modeling stage 15 and the linear area Al of the drum IC langeςΥΓτΠ * G for a position of the modeling stage 15, in which the slot area S can be formed, the setting of the modeler home position can be changed according to the size of the object in the direction of the Y-axis to be formed.
When the modeling stage 15 is placed in the mode-set home position, the feed nozzle 26 supplies the photocurable material R to the lower surface of the drum 10.
As mentioned above, as a light curing material R, for example, an ultraviolet curing type resin is used. As a result, the laugh hardening material R was called liquid resin R to. to simplify the description.
When the liquid resin R is transferred to the drum IC as described above by means of the control for the roller hammer 54, the rotary motor drives the guide rollers 4. Thereby, the drum 10 is rotated until a part of the drum 10 to which the liquid resin R is adhered is disposed in the lowermost part of the drum 10. Thereafter, the rotation of the drum 10 is held ar. The Schiit zbererch S and its edge are shown enlarged in Fig. 6 at this time. In this state, the irradiation of the liquid resin R with the laser light is started, i. with the exposure.
In some types of the liquid resin R, the liquid resin R flows downwardly from the drum 10 due to its own weight, so that there is a space separating the slit area between the lower one. Surface of the drum 10 and the upper surface of the modeling stage 15, is filled with the liquid resin R.
When the liquid resin R flows downward along the outer surface 10a of the drum 10 due to its own weight, the drum IC need not be rotated.
This is followed by irradiation with the. Base light through the irradiation unit 30. The laser light generated by the laser light source 31 passes through the objective lens 34 and penetrates through the drum 10 into the liquid resin R in the sliding area S. The irradiation unit 30 is controlled by the controller for the X-axis motion motor 55 to move in the direction along the X-axis. At the same time, the irradiation unit 30 selectively exposes the liquid resin R to the light in the direction of the X-axis on the basis of data for a row of a slice of the target to be modeled under the control of the laser power controller 52.
Specifically, the laser power controller 52 generates a laser power modulation signal based on the data for one row, and transmits the modulation signal to the laser light source 31. Thus, the liquid resin R is selectively exposed in the direction of the X-axis for a number of a layer with the light and cured. At least the liquid resin R in the slot area S is exposed to the light. During exposure by the laser light irradiation, the drum 10 is stopped. that one wavelength
As the laser light, a light is used 21 in the range of ultraviolet light has. Although the thickness for a layer of the article is in the range of 1 μπι to 100 gm, the thickness is not limited to such a range, and it can be adjusted accordingly.
When the exposure for a row is completed along the X-axis direction of the liquid resin R, the irradiation operation with the laser light is stopped. Thereafter, the Y-axis movement mechanism 70 moves the modeling stage 15 by a predetermined step in the direction along the Y-axis to the rear side (to the right side in Fig. 4B). This is followed by a targeted exposure for the next row of the first layer (a row next to the first row) in the manner mentioned above.
When the three-dimensional modeling apparatus 100 repeats scanning irradiation of the laser light along the X-axis direction and gradually shifts the modeling stage 15 along the Y-axis direction, as just described, as shown in FIG. 4C, the targeted hardening Layer parts of the liquid resin R formed for a layer, ie the object for a shift. As described above, simultaneously with a so-called luminous scan, the exposure process for one layer is performed. Although the step size of a stepwise movement of the modeling stage in the direction of the Y-axis, as described above, depends on the spot diameter of the laser beam, i. from the resolution, when the object is formed, the step size of the stepwise movement can be adjusted accordingly.
Fig. 7 is a view in which the liquid resin R and the hardened layer on the modeling stage 15 shown in Fig. 4C are shown on an enlarged scale. In Fig. 7, the cured layer portions Rl are shown black for a layer. As shown in FIG. 7, non-hardened liquid resin R adheres to the drum 10 on the right side downstream of the slit area S. Furthermore, a layer of uncured liquid resin R also adheres to the formed, hardened layer part R 1. However, there are no problems, and the reason for this later is 22 • * * * 4 «*« «* * * * * * * a • · · · ·« «* * * ···« φ • # · · · · * Φ should be described.
When the exposure for one row is completed along the X-axis direction, and the modeling stage 15 (and the moving base 11) are moved from the Y-axis moving mechanism 70 by the frictional force between the drum 10 and the drum
Modeling platform 15 were moved in the direction of the Y axis, the drum becomes. 10 taken and counterclockwise by Tig. 3 and 7 set in rotation. On the other hand, at this time, the guide rollers 5 can be driven by the roller motor 3 to thereby set the drum 10 in rotation.
At the time when the exposure for a row of the flux resin R is completed and the modeling stage 15 is stopped by a predetermined single step downstream with respect to FIG. 6), the modeling stage 15 is moved so that the drum 10 is separated from the modeling stage 15 in the Z-axis direction. hardened layer parts RI (hardened layer parts, which adhere to the outer circumferential surface 10 a of the drum IC) are cleanly detached from the drum 10.
Further, in the conventional interfacial process, the flatness of the article may be affected by an overstress of the thin film or the glass surface, which has been one of the problems. In contrast, in this embodiment, the shape of the outer peripheral surface 10a of the drum 10 is a curved surface (cylinder surface), the liquid surface being confined by the linear region A1. Even if the force of contraction when curing the liquid resin R is applied to the drum 10, it is not easily possible that deformation and overstressing of the drum 10 are caused. Furthermore, it is possible to prevent the deformation of the drum 10 by the viscosity of the liquid resin R before the exposure. This makes it possible to increase the flatness of the cured. Layer RI to improve and further their thickness with high accuracy to control. «· 23 *«
By an experiment, the inventor confirmed that, in comparison of the area which is a curved surface (for example, the outer circumferential surface 10a of the drum 10) to the surface, which is a flat surface (for example, the upper surface the hardened resin at the surface, which is a curved surface, is smaller than the flat surface, with the cured resin layer bending back on the flat surface rather than on the curved surface In this experiment, which obtained such a result, the curved surface and the flat surface were made of the same material.
Further, once a cured layer for a layer is formed on the modeling stage 15, the resin material for the subsequent cured layer exhibits a greater adhesion force to the previous layer made of the same material than to the outer surface 10a of the drum 10. It was confirmed to me that even if the radius of curvature of the glass confinement body is one meter, the hardened layer can be detached sufficiently cleanly.
Thus, in this embodiment, the cured layer can be reliably separated from the drum.
When the exposure for the liquid resin R for one layer is completed, the modeling stage 15 is lowered by the thickness for a layer of the hardened layer RI. Thereafter, the moving base 11 and the modeling stage 15 are moved from the position shown in Fig. 4C back to the modeling output position shown in Fig. 43. Although the Modellierbühne 15 has been lowered, can in this. In case the moving base 11 and the modeling stage 15 are moved back to the mode setting output heading.
When the exposure of the liquid resin R for one layer is completed; and the modeling stage 15 has been lowered, the guide rollers 5 are further trimmed, so that the drum 10 is moved by a predetermined angle against the guide shaft.

Clockwise of Fig. 3, 7 and the like is set in rotation. As a result, a used outer lateral surface 10 a of the drum 10, to which no liquid resin R adheres, is arranged opposite the modeling stage 15. The excess liquid resin R adhering to the outer surface 10a of the drum is regularly removed with a cleaning device (not shown).
Then, in the modeling process (exposure process) for the second layer, the uncured liquid resin R remaining on the hardened layer Rl, which is the first layer, is exposed to the light in the same process as that of the first layer Case was to thereby form a cured layer Rl, which is the second layer. Although layers of the article are stacked in the Z-axis direction in this manner, the liquid resin R is supplied to the drum 10 at regular intervals.
It need not be emphasized that the liquid resin R can be supplied for each layer or shorter interval or constant modeling process.
In the above description, the drum 10 is rotated by a predetermined angle after the exposure step for one layer is finished. In the case that adheres after the inner layer is carried out for a plurality of layers without the drum 10 being at a predetermined angle

Figs. 5A to 5C show for a Sch - Fr +. ^ +. This article is designed with the same process as shown in Figs. 4 was the case.
The three-dimensional modeling apparatus ICC may form an anchor pattern as follows. Fig. 8 is a view showing a pattern of the exposure process for one layer as seen in the 2-axis direction. In this example, along the direction of the X axis at the starting point and the end point of a scan, the laser light is radiated from the irradiation unit 30 to thereby form anchor pattern Rb as parts of the object. That is, the article (hardened layer RI) has a main body Ra and the armature patterns Rb formed around the main body Ra.
The armature patterns Rb are formed as described above, whereby it is possible to suppress adverse effects on the modeling accuracy resulting from a change in the scanning speed at the start and stop of the scanning by the irradiation unit 30. Thus, the exposure process for the edge parts Re in the X-axis direction of the main body Ra formed on the inside of the anchor pattern Rb can be unified in the Y-axis direction. Thereby, the Rar.dteile Re of the main body Ra can be formed with high accuracy.
In the example shown in FIG. 5, the anchor pattern Rb is made to have a linear shape along the direction of the Y-axis, for example. However, the shape of the armature pattern Rb along the Y-axis direction does not necessarily have to have a linear Ferm. The shape of the anchor patterns Rb may be in the form of a clip (for example, < >). Alternatively, the shape of the anchor pattern Rb may be a zigzag or a shape corresponding to the shape of the article. The length of the armature Rb in the direction of the X-axis can be set accordingly.
As described above, in this embodiment, the thickness for each layer of the article can be kept properly constant. Thereby, the uniformity of the flat surface of the hardened layer Rl for one layer can be improved. these
As described above, as described above, the modeling stage 15 is moved to separate the drum 10 from the modeling stage 15 in the Z-axis direction, thereby leaving the cured layer RI of the resin clean from the drum IC can be replaced.
In this embodiment, the linear area Al adjoins the liquid surface of the liquid resin R, and even if a resin material having a high viscosity is used, the article can be formed with a correct film thickness. This can be used to expand the selection area for the material to be used.
In the conventional interfacial process, it has taken a long time to detach the article from the thin film or the glass surface. In this embodiment, however, during the exposure process at the time of the stepwise advance of the modeling stage 15 in the direction of the Y axis, the object is detached from the drum 10. This means that and the Abtrenr Zeicintervai.1 for. Au can. the exposure process for a shift gang overlap in time, thus shortening the formation of the object
In this embodiment, on the linear portion A1 of the drum 10, the separation of the drum 10, which is the confining body, is gradually carried by the modeling stage 15 (for each stepwise feed along the Y-axis direction). Thus, the separation force is small and it is possible that damage of the hardened layer RI is prevented. This means that the hardened layer RI can be easily separated from the confining body. Furthermore, as described above, the forceps are small enough to prevent the hardened sloe RI from being separated from the modeling stage 15. lowest part of the IC is the lir.e aren eich al ur.d which is formed at

Further, as compared with a case where the irradiation of the laser 30 is located outside the slub 10, the size of the three-dimensional modeling apparatus 100 can be reduced.
[Second Embodiment;

In the description that follows, the description will be made. similar components, functions, and the like already included in the three-dimensional Modiervercrricntung 100 according to the Ausführur.gsform of Fig. 1 and the like, simplified or omitted, while different points are substantially described.
A three-dimensional modeling apparatus 200, as shown in Fig. 9, has a plate member 20 having a surface formed as a curved surface instead of the above-mentioned drum, which is not used as a confining member. Flatten element 20 is typically part of a cylinder body. Flatten element 20 has a lower surface 2Ca and an upper surface 20b. The lower surface 2Ca is the Modellierbühne 15 and, for example, by a plurality of guide rollers 45 and 4 6 worn. The upper surface 20b is held by a guide roller 47. On the side of the upper surface 20b of the plate member 20, the Eestrahiungseinheit 30 is arranged.

Substantially flat surface can be considered, and the modeling brush 15 (the cured layer RI on the modeling stage 15) of the slot area S ausgebilaet. In the case where the drum 10, which is a cylinder body, is used as in the first embodiment, as the diameter of the cylinder body is made larger, the curvature of the outer surface becomes smaller. Thus, the area of the linear area Al, which can be regarded as a flat area, can be made larger. However, when the diameter of the cylinder core is made larger, the three-dimensional modeling apparatus also becomes larger. In view of this, the retainer is made to have the shape of a plate in this embodiment. Thus, it is possible to make the three-dimensional modeling apparatus 200 smaller and the area of the linear one. To increase the area Al, which can be regarded as a flat surface.
It should be noted that the plate member is not limited to the embodiment in which the plate separator is a part of the cylinder body, the shape, as seen from the side surface in Fig. 9, being a shape that is oval , Curve or part of a square curve corresponds, for example, a hyperbola.

In the case where the confinement body is formed to have the shape of a cylinder as in the three-dimensional modeling apparatus ICO. 1, the irradiation unit 30 is provided inside the drum 10. In this case, the length of the optical path of the laser light is limited. However, as is the case with the embodiment, if the half cylinder body 40 having a shape obtained by cutting out a cylinder body is used, the restriction of the length of the optical path of the laser light can be eliminated.

That is, the Z-axis moving mechanism 17 horizontally moves the Y-axis moving mechanism 7C to thereby cause the modifying stage 15 to approach or be separated from the drum 10. In the description of this embodiment, the vertical direction is referred to as the direction of the Y axis, and an approaching and separating direction (the horizontal direction) of the modifying stage 15 with respect to the drum 10 is referred to as the Z-axis direction. concerns, so

As the cleaning liquid discharged from the cleaning nozzles 28 and 38, for example, ethanol or methanol can be used. From the air inflation nozzles 29 and 39, another gas, for example an inert gas, may be inflated in addition to air.
In the lower part of the drum 10, a waste container 18 is provided. In the waste container 18, excess material (liquid resin), the cleaning liquid and the like are stored.
Now, an operation of the three-dimensional modeling apparatus 30C constructed as described above will be described. The operation of one layer of the article will now be described.
When the feed nozzle 26 supplies the liquid resin to the outer peripheral surface 10a of the drum 10, a guide roller (not shown) driving the drum 10 is driven. In Fig. 11, the drum 10 is rotated, for example, by a predetermined angle in the clockwise direction. When the drum 13 has been rotated, the liquid resin adhered to the drum 10 is moved to the slit portion formed between the linear portion AI of the drum 10 and the modeling stage 15. Alternatively, the liquid resin adhering to the drum 10 may flow downward on the outer surface 10a due to its own weight and be supplied to the slit portion.
The liquid resin is held in the slot area due to its own surface tension. Further, while the irradiation unit 30 is scanning in the X-axis direction, the modeling stage 15 is moved downwardly in the Y-axis direction from the state shown in FIG.

Further, the rhyme unit 37 supplies the cleaning liquid and the air to the drum 10, and excess liquid resin adhering to the outer surface of the drum 10 is also removed.
Such a process for a layer of the article is repeated in a predetermined number and the article is formed.
In this embodiment, the excess material can be reliably removed from the hardened layer Rl by flowing down the excess material due to gravity, thereby cleaning the surface of the hardened layer Rl. Thus, the modeling can be realized with a hc-hen accuracy.
The timing for cleaning with the cleaning units 27 and 37 can be optionally set. For example, cleaning may be performed with the cleaning units 27 and 37 for each aer layer of the article or for a plurality of the layers of the article. Alternatively, such cleaning may be carried out throughout the modeling process. The cleaning liquid flows down, which in this fourth embodiment, no Luftaufblasdüse is required.

Except for this, the three-dimensional modeling device 313 has substantially the same structure as the three-dimensional modeling device 300. The color nozzle unit 4 8 has a nozzle 4 8R supplying a red-colored liquid resin, a nozzle 4 SG feeding a green-colored liquid resin, and a nozzle 483 which supplies a blue-colored liquid resin. That is, the three-dimensional modeling apparatus 310 can make a completely colorful object. The arrangement of the nozzles 48R, 48G and 48B can be changed accordingly. As shown in Fig. 13A, the nozzle 48R supplies the red liquid resin into the slit area. While the irradiation unit 30 (see FIG. 11) is moved in the X-axis direction, the red liquid resin supplied into the slit area is irradiated with the laser light from the irradiation unit 30. Further, when stepwise feeding occurs, the modeling stage 15 is moved in the Y-axis direction to form red cured layer portions Rl (R) for one layer. Thereafter, as shown in Fig. 13B, the cleaning unit 27 removes excess liquid resin. one instead

The dot diameter of the laser light from the
Irradiation unit can be adjusted accordingly, whereby the colorful object can be formed, which ranges from a weak resolution to a. raise resolution depending on the resolution of the irradiation of the laser light depends. If, for example, the spot diameter of the laser light is about 10 .mu.m, a high-resolution coloring can be carried out.
As described above, in this embodiment, the modeling stage 15 is moved in the vertical direction, making it easier to remove excess material. It thus becomes easier to remove the excess material for each layer, and it is easier to form an article having different colorants for each layer.
According to this embodiment, it is possible to color the inside of the article as well. Thus, for example, when the user cuts the object, he finds the cut colorful. Although the user desires that the structure of the cut of the article be expressed, this embodiment has a merit.
It should be noted that in this embodiment. Cyan, Magenta, Yellow (Cyan, Magenta, Yel_ow, CMY) liquid resin can be used instead of RGB liquid resin.
When transparent resin is used in addition to the RGB or CMY, it is also possible to form a transparent article that is colorful in its interior or on its outer surface.
If white liquid resin is used in addition to RGB or CMY, white may represent a base color for the article. Demi .. it is possible to realize a Geoerstand that is colored more clearly.
When white liquid resin and black liquid resin are used instead of RGB or CMY, an object can be formed with a gray scale. 36 * * * ι

[Sixth Embodiment]
Fig. 14 is a view describing a sixth embodiment of the present disclosure.
In this embodiment, a slit coating nozzle 26 is used as a supply nozzle supplying the resin material. Furthermore, a thixotropic material is used as the resin material. Both the drum 10, the plate member 20, the half-cylinder body 40, and the like may be used as a confining body as long as they have a linear range Al.
The slit coating nozzle 26 supplies thixotropic liquid resin R2 to form a thin film having an overhanging shape, as shown in the drawing.
In the past, as a method of forming an article having an overhanging part, a method of using, for example, has been used. In particular, in this method, a light-curing resin material containing a light-absorbing additive was used, whereby the intensity of the laser light to be radiated is controlled to thereby limit the depth at which the photohardening resin material is cured , In this method, however, it is not possible to precisely control the depth of cure and to change the cure depth
To control surface roughness of the overhanging part.
In this embodiment, the thixotropic material R2 is used, making it possible to form an overhanging part A3 with high accuracy regardless of the curing thickness. Further, in this embodiment, by using the nozzle 26, which is a slide coating nozzle, the thin film having an overhanging shape can be formed.
Specifically, the confining body having the linear region A1 is used, thus making the separation force of the object from the confining body (the drum 10) very small, as described above, making the force applied to the counter sinus very small becomes. Thus, a thin, overhanging part can be formed.
The thickness of the thin film of the overhanging part R3 can be set to be smaller than the wall thickness of the drum 10.
Compared to the intensity of the laser light with which the hardened layer (the hardened layer RI in the lower part of the object) is formed, which is not the overhanging part R3, the intensity of the laser light can become the instructor, the overhanging part R3 be set larger. With this setting, it is possible to reliably cure the liquid resin of the overhanging part R3.
The material for the cured layer (the hardened layer RI in the lower part of the article), which is not the overhanging part R3, may be different from the material for the overhanging part R3. In this case, it is sufficient that supply nozzles are provided, each supplying their materials. For example, the fourth embodiment and the fifth embodiment may be applied to the sixth embodiment.
The thixotropic material R2 may be applied to the first to fifth embodiments. 38 • ♦ * · · * • · «· · · · · · * * * * · · · ·
Instead of the thixotropic material R2, a gelatinous material formed to have the Ferm of a thin film may be wound around the outer circumferential surface 10a of the drum 10, whereby the gelatinous material may be exposed to the light to thereby form the overhanging part Train R3.
The Flg. ISA to 15C show a view showing an example of an article having an overhanging part. This article is used, for example, in a microchannel device.
On hardened layer parts 102 constituting the channels 101 formed as shown in Fig. 15A, a lid member 103 is formed as a thin film having an overhanging part, as shown in Fig. 15B.

[Eighth A.Expiration 1 erm]
Fig. IS is a view showing main parts of a three-dimensional modeling apparatus according to an eighth embodiment of the present disclosure.
A three-dimensional modeling device 333 according to this embodiment has an inclined surface 59. Along the inclined surface 5 9, a first set 41, which is provided on an upper side, and a second set 42, which is provided on a lower side.

Thereafter, the first set 41 performs an exposure operation and a cleaning operation on the modeling stage 15. The exposure process and cleaning process are as described above in connection with FIGS. 11 and 12. Excess liquid resin and cleaning liquid flowing down during the exposure and cleaning operations pass through a drainage channel provided along the inclined surface 59, and are discharged into a waste container (not shown) or the like.
When the first set 41 completes the exposure operation and the cleaning operation, the modeling stage 15 is further lowered. The second set 42 then initiates an exposure process and a cleaning operation on the modeling stage 15. The second set introduces the operations to form a layer having the same height (elevation in the direction of raising and lowering of the raising / lowering mechanism 14) as the hardened layer formed with the first set 41 ie without changing the height of the modeling stage 15 between the first set 41 and the second set 42. 42 »* • ι * 4 • *

This is a merit when the inclined surface 59 is used.
In this way, the modeling process with two kinds of materials is carried out while the cleaning unit 27 performs the cleaning for each layer. Thereby, similar to the embodiment of FIG. 13, it is possible to form the article containing two kinds of material with high accuracy.
Comparing the fifth embodiment shown in Fig. 13 with this embodiment, in the fifth embodiment, it is necessary to set the modeling stage 15 to the home position every time one of the liquid resin is supplied, but this movement is at this embodiment is not necessary, this being an advantage of this embodiment. However, the three-dimensional modeling apparatus 310 according to the fifth embodiment has a merit that the size of the apparatus such as the footprint of the apparatus can be reduced and the number of components can be reduced as compared with the three-dimensional modeling apparatus 330 according to this embodiment.

From a starting position of the modeling stage 15, which is shown in the drawing, the Modellierbühr.e 15 is lowered, wherein the first set 43 performs an exposure process on the modeling stage 15. After the first sauz 43 finishes the exposure operation and before or while the modeling stage 15 is lowered, the Z-axis movement mechanism 16 retracts the modeling stage 15 along the Z-axis direction by a predetermined distance. In order to prevent the hardened layer RI formed by the first set 43 from obstructing the second set 44, the modeling stage 15 is retracted a predetermined distance, as described above.
When the modeling stage 15 is lowered to a position where the hardened layer R1 can be cleaned with the cleaning unit 27, the hardened layer R1 is cleaned with the cleaning unit 27, and excess liquid resin and riding liquid are discharged into the waste container 18.
When the cleaning unit 27 stops the cleaning operation, the modeling stage 15 is raised to a step in which an exposure step with the second set 44 can be performed. Thereafter, the modeling stage 15 is guided back by the distance by which the modeling stage 15 has been retracted in the Z-axis direction. The second sentence then gives 4 Fiüssigharz, which is a liquid resin other than that of liquid resin, that of the first.

In each of the above-mentioned embodiments, the mode-positioning stage 15 has a movement structure that can move in two axes, the Y-axis and the Z-axis. In addition to the movement structure for two-axis movement, there may be provided a rotary mechanism which rotates the mode-setting stage 15 around the up-layer direction [Z-axis direction) of the age-hardened layers. For example, in a case where scanning with the dasher light is made only in the direction of the X-axis (a predetermined direction), in some states of the modeling process after the object is removed from the processing stage 15, there is a risk of deformation (Eir.f points or vaults) can be generated in the subject. With the above-mentioned rotating mechanism, scanning with the laser light in a desired direction can be performed. For example, while the mode-setting stage 15 is rotated by a predetermined angle for each layer, for a plurality of layers or randomly, the article is formed, whereby such deformations on the object can be prevented. Under the given. Angle is, for example, an angle of 30 °, 90 °, 18 ° or the like, to understand a combination thereof or an indefinite angle. 46 4 «·« ·· * ··· «Μ • 4« * · * «·· 4 ·· * · * · *« «• 4 · * 4 · · · ··· In any of the above-mentioned embodiments, the surface of the confining body (for example, the outer circumferential surface 10a of the drum 10) may be provided with a protective thin film. In particular, a protective thin film is wrapped around the surface of the limb. Thus, the surface of the confinement body can be cleaned by appropriately removing the treasure thin film instead of cleaning the surface of the confining body. Alternatively, the protective thin film made of Teflon (registered trademark) may be preliminarily formed on the surface of the confining body, thereby suppressing liquid resin or the like from being left. In this case, for example, it is possible to clean the surface by simply cleaning it or blowing it off with gas.
As Schurz Oünnschicht a material is used, which is permeable to the energy radiation. In order to form the protective thin film of the permeable material, for example, a polycarbonate, polyethylene, polyvinyl chloride or the like is used.

Since a time interval in which all of the many laser beams are susceptible to being suspended, comprising a time interval in which at least two laser beams of the plurality of laser beams are simultaneously irradiated, irradiation mechanisms are controlled with the control unit. Typically, all laser beams are susbstrahit substantially simultaneously. Thus, the exposure process can be realized in a wide range on the material at the same time, whereby the time interval necessary for the modeling process can be reduced. In this example, a plurality of laser light sources may be provided, or n (n is an integer equal to or greater than 1) light sources may be used, and the laser beam may be divided into a plurality of laser beams, thereby n + 1 or more Auszubiiaen laser beams.
For example, although the colored liquid resin is used in the above description to form the colored article 47, instead of this liquid resin, a material obtained by mixing colored fillers into the liquid resin may be used. For example, a material obtained by mixing colored microparticles each having a size smaller than the minimum coating thickness into the liquid resin can be used. The microparticles used are glass, resin, metal powder, starch, gypsum, salt, sugar or the like.
Alternatively, as the filler, for example, a transparent or white filler may be used, and such a filler may be dyed with a dye.
If the coating thickness of the article is sufficiently small, a beautiful, colorful article can be formed only by using one color for each layer.
The material for the article is not limited to light-curing material, but a material which can be cured by heat energy, electron beam, or ultrasound can be used. Furthermore, depending on the material, the energy radiation emitted by the irradiation unit may also be changed accordingly. As energy radiation, in addition to ult ravt, it ropes. Radiation infrared radiation, visible light, an electron beam, heat radiation and an ultrasonic wave are exemplified. The heat radiation may be an infrared radiation, in which case the curing process is carried out with a point heating ir.with an infrared laser. The heat radiation, the ultrasonic wave or the like is used, for example, to image an object having a relatively low modeling accuracy.
In the above-mentioned embodiment. the guide rollers 5 and the like are shown as a mechanism that the. Bearing body (the drum IC, the plate member 20, the half cylinder body 40 or the like) carries so that it can be set in Drenung. The Fiihmngsrollen can also be replaced by bearings. In this case, it suffices that a support member having a rotating shaft supports the confining body, and the bearings are connected to the rotary shaft.
Although in the above-mentioned embodiment, the mocolliming stage 15 is moved in the Y-axis direction, the confining body and the irradiation unit may also be moved in the direction of the Y-axis.
In a case where the drum 10 is used as a confining body, the drum 10 may have a solid structure unless high modeling accuracy is required.
As shown in Fig. 9, as a confining body, the plate member 20 having the curved surface can be replaced with the plate member having the flat surface, and this plate member can be held to be deflected by its own weight. As a support mechanism, the guide rails can be used, which are shown in Fig. 9 dargesteilt.
In the three-dimensional modeling apparatus according to each of the above-mentioned embodiments, a roller or a squeegee may be provided to remove the excess liquid resin of the hardened layer. The roll or doctor blade may be provided instead of the cleaning unit 27.
