具体实施方式 detailed description

[0016] 为了使本技术领域的人员更好地理解本申请中的技术方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。 [0016] In order to make those skilled in the art better understand the technical solution of the present application, in conjunction with the following drawings of the present application example embodiments, the technical solutions in the present application will be clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present application, rather than all embodiments. 基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本申请保护的范围。 Based on the embodiments of the present application, all other embodiments to those of ordinary skill in the art without creative efforts shall be made available, should belong to the scope of the present application.

[0017] 参见图1,该图示出了本申请的光固化快速成型装置实施例的组成结构。 Composition structural embodiment of the device [0017] Referring to Figure 1, which shows the application of the present Stereolithography. 该实施例包括:承载体101、成像部件102和光源103,承载体101与光源103位于成像部件102的异侧,其中: This embodiment comprises: a carrier body 101, an imaging light source 103 and the member 102, the carrier 101 and the opposite side of the imaging light source 103 body member 102, wherein:

[0018] 承载体101,该承载体用于承载流体状态的光敏树脂100,实际应用过程中,该承载体可以是具有包容形状的容器,比如U型容器,这通常适用于要求深度厚、边缘部分规整的成型对象,也可以体现为平板结构的载体,这通常适用于要求深度薄、面积大、主体部分规整的成型对象;[0019] 成像部件102,该部件用于展现待成型对象截面的二维图形,展现在成像部件上的二维图像通常可区分为两个连通区域,即二维图形本身包含的区域和二维图像之外成像部件表面范围之内的区域,这两部分区域的透明状态相反,即包括两种情形:一种情形是二维图形部分为暗色状态(不能透过光线)、其他部分为透明状态(可以透射光线),另一种情形是二维图形部分为透明状态、其他部分为暗色状态。 [0018] The carrier 101, the carrier member for carrying a fluid state photosensitive resin 100, the actual application process, the carrier may be a container having a shape inclusive, such as U type container, which is usually applied to a thickness of the desired depth, the edge shaped part structured objects, may be embodied as a carrier plate structure, which is generally applied to the desired depth of thin, large area, forming the body portion of the structured objects; [0019] 102 imaging member, means for presenting the objects to be molded section dimensional graphics, to show the two-dimensional image on the imaging area may be generally divided into two communicating regions member, a surface area within the region and outside the scope of the two-dimensional image forming means that is included in the two-dimensional pattern itself, the two parts of region Instead transparent state, i.e., including two cases: one case is a two-dimensional pattern is a dark state portion (impervious to light), the other part is transparent state (can transmit light), another scenario is a two-dimensional pattern of transparent portions state, the other part is the dark state. 前者由于暗色部分不能透过光线,被该暗色区域遮住的光敏树脂将不发生聚合反应,不会固化成型,而其他部分则可以迅速固化,这种情形适用于制作包容二维图形的(镂空)模具,类似于汉字雕刻的阴刻法;后者由于暗色部分为二维图形之外的区域,这部分区域没有光照不发生聚合反应,不被固化,其他部分在光照下发生固化,这种情形适用于制作二维图形本身形状的工件,类似于汉字雕刻的阳刻法。 Since the dark portion can not pass through the former light is blocked in the dark areas of the photosensitive resin polymerization will not occur, the molding is not cured, while other parts can be rapidly cured, which applies to the production of two-dimensional pattern of inclusion (hollow ) mold, similar characters engraved intaglio method; latter is due to the dark portion pattern other than the two-dimensional area, which is not part of the illumination region polymerization did not occur, it is not cured, partially cured other in the light, this It applies to the shape of the workpiece itself, making two-dimensional pattern, similar to the male characters engraved etching method. 本实施例的成像部件具体实现时可以是任何能够成像的物理设备,这里“成像”的含义可以是机械性的,比如,通过人工将待成型的目标成型体的截面图形粘附在成像部件的表面上,这通常适用于小规模的快速成型的场景;也可以是电子性的,比如通过自动化设备产生控制信号,在成像部件的表面成像出二维图像,常见的如液晶屏,可以通过电路控制液晶屏上的二维图形的形状,这较多地适用于大规模的快速成型的环境。 When the imaging member of the present embodiment example of specific implementation may be any device capable of imaging the physical meaning of "imaging" herein may be mechanical, for example, by forming the sectional pattern of the target molded article to be adhered to the artificial member imaged on the surface, which is usually applied to rapid prototyping small scene; may be the electron, such as generating a control signal by automated equipment, forming a two-dimensional image, the liquid crystal panel in a common surface of the imaging member can be produced by the circuit control the shape of two-dimensional graphics on the LCD screen, which is more suited to large-scale rapid prototyping environment. 此外,采用液晶屏作为成像部件在现有工艺下比激光振镜或DLP具有更高的分辨率。 Further, a liquid crystal panel as an image forming member having a higher resolution than a laser galvanometric or DLP in the existing process.

[0020] 光源103,用于使流体状态的光敏树脂发生聚合反应的光源103,光源103与承载体101位于成像部件102的异侧。 The light source [0020] the light source 103, for a photosensitive resin in the fluid state of the polymerization reaction 103, light source 103 and the carrier 101 is located opposite side of the imaging member 102. 在实际应用过程中,考虑到流体状态的光敏树脂的发生聚合反应的速度、深度等因素,可以对光源的作用谱段进行适当选择,比如,经实验证明,本实施例可以优选光源的波长在350至400纳米范围的光源。 In practical applications, the factor speed occurs taking into a fluid state photosensitive resin polymerization, the depth and the like, may be suitably selected to effect spectral light source, for example, experiments show that the present embodiment may be a wavelength preferred source of the light source 350 to 400 nanometers.

[0021] 本实施例的光固化成型装置的工作原理是:光源103发出光后,由于成像部件102展现的二维图形与二维图形之外的区域存在不同的明暗状态,照射到成像部件102上的光线一部分能够透过成像部件中的透明部分照射到流体状态的光敏树脂上,另一部分不能透过成像部件的光将无法照射到流体状态的光敏树脂上,从而使得流体状态的光敏树脂出现两种不同的变化方向:被光线照射到的流体状态的光敏树脂将发生聚合反应迅速固化,没有被光线照射到的流体状态的光敏树脂不发生聚合反应,仍然保持原有状态。 Works stereolithography apparatus [0021] according to the present embodiment is that: after the light source 103 emits light, since the two-dimensional pattern area other than the imaging member 102 with the two-dimensional pattern exhibited by the presence of different shading state, is irradiated to the imaging member 102 can be a portion of the light rays onto the photosensitive resin in a fluid state, the light transmitted through another portion of the imaging member can not be irradiated to the fluid state portion of the imaging member is irradiated through the transparent photosensitive resin, so that the photosensitive resin in a fluid state occurs Two different direction of change: a photosensitive resin is irradiated with light to cure the liquid state to the polymerization reaction occurs quickly, a photosensitive resin is not light is irradiated to the fluid state of the polymerization reaction does not occur, still maintaining the original state. 如果二维图形为暗色状态,经过上述过程后,将呈现出包容二维图形的固化光敏树脂成型体;如果二维图像为透明状态,经过上述过程后,将直接成像出二维图形的固化光敏树脂成型体。 If the two-dimensional pattern is a dark state, after the above process, will exhibit cured photosensitive resin molded body inclusive of the two-dimensional pattern; if the two-dimensional image of a transparent state, after the above-described process, the curing of the photosensitive direct imaging of two-dimensional figure resin molding.

[0022] 本实施例的光固化快速成型装置包括承载流体状态的光敏树脂的承载体、展现二维图像的成像部件以及用于照射光敏树脂的光源,光源与承载体位于成像部件异侧。 [0022] Example embodiment of the present photocurable rapid prototyping apparatus comprising a photosensitive resin carrier carrying a fluid state, exhibits two-dimensional image forming member and a light source for irradiating a photosensitive resin, the light source and the carrier of the imaging member opposite side. 与现有技术相比,本实施例至少可以取得如下三方面的技术效果:(I)由于本实施例实现光固化快速成型过程中的光路部分仅由成像部件和光源组成,位置关系简单,降低了光固化过程的光路复杂度,减少了光路延迟,而且减少了插入光路元件(比如透镜、反射镜)带来的像差、畸变等光学误差,从而提高了光固化快速成型效果。 Compared with the prior art, the present embodiment can achieve the technical effect of at least the following three aspects: (I) Since the present embodiment realizes rapid photocuring path portion during molding only by the imaging means and the light source, with the simple positional relationship, reduced the complexity of the optical path of the light curing process, the optical path delay is reduced, but also reduces the error of the optical element into the optical path (such as a lens, a mirror) to bring aberration, distortion and the like, thereby improving the effect of stereolithography. (2)本实施例的装置包括三个组成部件,其结构简洁、部件数量少,降低了光固化快速成型装置的总体积。 (2) The apparatus according to the present embodiment includes three component parts, simple structure, small number of parts, reducing the total volume of Stereolithography apparatus. (3)本实施例的装置采用的成像部件相对于技术的激光振镜或DLP投影仪而言,制作成本低、使用材料少。 (3) the imaging member of the present embodiment using the apparatus of the embodiment with respect to galvanometer laser projector or DLP technology, the production cost is low, the use of less material.

[0023] 需要说明的是,在实际应用过程中,上述实施例的承载体101和成像部件102可以合“二”为“一”,作成一个部件,即:使成像部件同时作为承载流体状态的光敏树脂的承载体,或者使承载流体状态的光敏树脂的承载体同时具有展现二维图形的功能。 [0023] Note that, in practical applications, the carrier of the above Example 101 and the imaging member 102 may be bonded "two" to "a", made a member, namely: that the imaging means while a state carrier fluid carrier photosensitive resin or photosensitive resin of the carrier body while having a carrier fluid state exhibits the function of two-dimensional graphics. 同样地,还可以将上述实施例的光源103和成像部件102合“二”为“一”,作成一个部件,即:使成像部件展现的二维图形同时具有发光的功能(比如,采用等离子电子屏),或者,使光源呈现出二维图形的图像(比如,对多个光源单元的发光状态进行控制,使这些光源单元的整体呈现出二维图形)。 Likewise, also the light source 103 of the above embodiment and the imaging member 102 engaged "two" to "a", made a member, namely: that the two-dimensional pattern imaging member exhibited while having a function of emitting light (for example, by plasma electrons screen), or a two-dimensional image of the light source showing a pattern (for example, a plurality of light emitting state of the light source unit controls the entire light source unit showing the two-dimensional pattern).

[0024] 上述实施例的方案尽管能够实现本申请的发明目的,但是,在实际应用过程中,不仅需要制作出“二维图形”形式的薄片结构的固化成型体,而且更多的需求是制作立体形状的“三维结构”的固化成型体。 [0024] Although the embodiments of the above embodiments can achieve the object of the invention of the present application, however, in the actual application process, not only to produce a cured molded sheet structure "two-dimensional pattern" form, and more demand is made "three-dimensional structure of" three-dimensional shape of the cured molded article. “三维结构”的固化成型体可以看作是由多个二维图形截面累积贴和而成,这样可以将上述成型的过程连续循环进行即可实现该目的。 "Three-dimensional structure" of the cured molded article can be regarded as a plurality of two-dimensional pattern and a cross-sectional accumulation paste made, which can be the above-described process of forming a continuous cycle to achieve the object. 为此,本申请还优选包括移动部件和输送部件,移动部件用于在产生新的空隙,在该空隙内注入新的流体状态的光敏树脂,然后进行上述的光照过程,再次出现固化成型体,该固化成型体粘附在上次的固化成型体上,多次进行这样的操作,即可得到需要的三维结构的固化成型体。 To this end, the present application further preferably comprises a movable member and the conveying member, means for moving in a new gap, a new photosensitive resin is injected in a fluid state in the gap, then the above-described light process, the cured molded article again, the cured molded article is adhered to the last cured molded article, such operations several times, to obtain a cured molded article of the required three-dimensional structure. 这里的移动部件和输送部件可以采用多种具体实现方式,下面列举两种方式予以说明: Here the movable member and the transport member may take a variety of specific implementations, include the following be explained in two ways:

[0025] 方式之一:参见图2,在上述装置实施例的基础上进一步包括第一移动部件204和第一输送部件205 (从而构成本申请的又一个光固化快速成型装置实施例,与前述实施例相同的部件分别标号为承载体201、成像部件202、光源203、流体状态的光敏树脂200),第一移动部件104用于在承载体内的流体状态的光敏树脂固化成型后,将已固化成型的光敏树脂向远离光源的方向移动第一间隙,第一输送部件105用于向承载体内输送新的流体状态的光敏树脂,以填充所述第一间隙。 [0025] One way: Referring to Figure 2, further comprising a first moving member 204 and the conveying member 205 on the basis of a first embodiment of the apparatus (so as to constitute a further application of the present Stereolithography apparatus of the embodiment, and the the same components are designated carrier in Example 201, the imaging member 202, a light source 203, a photosensitive resin in the fluid state 200), the first moving member 104 for forming the photosensitive resin cured body of carrier fluid state, which has been cured photosensitive resin molded move away from the source of the first gap, the first conveying member 105 for conveying the photosensitive resin in a fluid state to a new carrier body, so as to fill the first gap. 本方式中的移动部件可以表现为一个机械支架,输送部件也可以表现为机械传动装置,这里的“第一间隙”通常选择小于流体状态的光敏树脂的固化深度,以使注入的流体状态的光敏树脂能够得到充分的固化。 Moving member in this embodiment may be expressed as a mechanical support, the conveying member can also be expressed as a mechanical transmission, here a "first gap" is generally less than the selected depth of cure the photosensitive resin in a fluid state, so that the injected fluid state photosensitive the resin can be fully cured. 在实际应用过程中,除这种对“间隙”的约束条件外,根据进一步实现的目的不同还可能强化对该间隙的限制:如果重点考虑的是固化成型的效果,在满足小于光敏树脂的固化深度的条件下,该间隙可以尽可能小,使光固化的每个“层”尽可能的薄,从而一方面可以提高成型的分辨率和精度,一方面使“层”与“层”之间粘附更稳固,增强三维立体结构的稳定性;如果重点考虑的是固化成型的速度,在满足小于光敏树脂的固化深度的条件下,该间隙可以尽可能大,使光固化的每个“层”尽可能厚,从而使成型相同高度的三维立体结构的成型体的光固化的次数变少,提高光固化的整体速度。 In practical applications, in addition to constraints on such "gap" is, depending on the object is further achieved may also limit the gap reinforcing: if important consideration is the effect of curing and molding, satisfy the cured photosensitive resin is less than deep conditions, the gap may be as small as possible, so that each "layer" photocurable as thin as possible, so that one can improve the resolution and accuracy of molding, on the one hand that the "layer" and "layers" between adhesion more stable, enhancing the stability of the three-dimensional structure; if important consideration is the speed of curing and molding, under conditions of less than the depth of cure of the photosensitive resin, the gap may be as large as possible, so that each layer of a photocured " the number of light-cured molded article "as thick as possible, so that the same molded height of the three-dimensional structure is reduced, improving the overall speed of the photocuring.

[0026] 方式之二:在上述装置实施例的基础上进一步包括第二移动部件和第二输送部件,第二移动部件用于在所述承载体内的流体状态的光敏树脂固化成型后,将成像部件向远离所述承载体的方向移动第二间隙,第二输送部件用于向所述承载体内输送新的流体状态的光敏树脂,以填充所述第二间隙,所述第二间隙小于流体状态的光敏树脂的固化深度。 [0026] bis embodiment: the movable member further comprises a second base and a second conveying member in the above-described embodiment apparatus, the second moving member for the photosensitive resin forming the cured body of the carrier fluid state, imaging a second member moves away from the gap in the direction of the carrier member, second means for transporting said carrier to a fluid state in vivo delivery of a new photosensitive resin, to fill the second gap, the second gap is less than a fluid state depth of cure of the photosensitive resin. 这种方式和第一种方式的移动方向相反,这是考虑到在实际应用中可能移动承载液体状态光敏树脂的承载体比移动成像部件更难,因此,采取移动成像部件的方式更容易实现。 In this manner and the movement direction is opposite the first embodiment, the carrier which is taken into account in practical applications may move the carrier in a liquid state photosensitive resin is harder than the moving imaging member, therefore, take the form of moving the imaging member is more easily achieved.

[0027] 上述在第一个实施例基础上改进的实施例能够制作出三维立体结构的成型体,而并没有对成型的形状进行任何限制,实际上,在工业制造成形体时,不仅需要制作每个截面均相同的成型体(比如,柱体型成型体),还需要制作每个截面均不同的成型体(比如,葫芦型成型体),在后者情况下,还需要改变成像部件中呈现的二维图形(即目标成型体的截面图形),这时可以通过一般的控制电路向成型部件输出不同的二维图形,从而得到具有不同截面的目标成型体。 [0027] The modified embodiments based on the Examples can be produced a molded body showing three-dimensional structure, and are not any restrictions on the molded shape, in fact, when the industrial manufacturing molded, not only need to produce a first each section are the same as the molded product (for example, column size molded body), but also need to produce each section are different molded body (for example, gourd-shaped molded body), in the latter case, also need to change the present image forming member two-dimensional pattern (i.e., the target molded article sectional pattern), then the control circuit can be formed by a common member of the two-dimensional pattern of different outputs to obtain desired molded bodies having different cross sections.

[0028] 上述内容详细叙述了本申请的光固化快速成型装置实施例的组成结构,下面结合附图对该装置实施例的工作过程进行详细叙述。 [0028] The foregoing detailed description of the structural composition of embodiment of the device according to the present disclosure Stereolithography, described in detail below in conjunction with the operation of this embodiment of the device in the figures. 参见图3,该图示出了本申请的光固化快速成型装置的工作过程。 Referring to Figure 3, which shows the present disclosure Stereolithography apparatus during operation. 该工作过程包括: The work process include:

[0029] 步骤S301:向承载流体状态的光敏树脂的承载体内注入流体状态的光敏树脂,在展现二维图形的成像部件上展现二维图形,所述成像部件展现的二维图形所在区域与二维图形之外的成像部件范围内的其他区域的透明状态相反; [0029] Step S301: injecting a fluid state photosensitive resin to the photosensitive resin onto a carrier carrying a fluid state, exhibits two-dimensional pattern on the imaging member exhibits a two-dimensional pattern, said two-dimensional pattern Area and the imaging member exhibits two in contrast to other regions in the transparent state imaging member outside the scope of the pattern dimension;

[0030] 本步骤包括两个子步骤:注入光敏树脂和展现二维图形的步骤,这两个步骤均是完成光固化快速成型的必要步骤,但是,由于他们均属于光固化成型的两个准备性步骤,本申请并不限定他们的执行顺序,可以先进行注入光敏树脂的步骤,也可以先进行展现二维图形的步骤,或者两个同时进行,这取决于实际应用过程中考虑的因素和面临的环境。 [0030] This step comprises two sub-steps: a photosensitive resin injection step and two-dimensional graphics show, these two steps are necessary to complete the steps of Stereolithography, however, because they belong to two of stereolithography preparatory step of the present application is not limited to the order of their execution may be performed before the step of injecting the photosensitive resin, the first step may be to show the two-dimensional graphics, or both simultaneously, depending on the factors considered during practical application and facing environment of.

[0031] 步骤S302:使用与所述承载体位于所述成像部件异侧的光源照射所述成像部件,以便透过所述成像部件展现的二维图像所在区域或二维图像之外的成像部件范围内的其他区域使流体状态的光敏树脂固化成型; [0031] Step S302: using the imaging member body is located outside the light source of the imaging member opposite side of the imaging member, said imaging member so as to show through the two-dimensional image or a two-dimensional image bearing Area other areas within the range of the fluid state of a photosensitive resin cured molded article;

[0032] 经过本步骤后“单层”的光固化成型体即已制作完成,如果进行光固化的目的仅在于得到这样“单层”的成型体,则可停止进行后续步骤。 [0032] After this step, "monolayer" photocurable already finished molded article, if the object is only to obtain photocurable that this "monolayer" of the molded body can be stopped subsequent step. 如果需要制作立体的三维结构的成型体,则需要连续多次进行液体状态的光敏树脂的注入操作和移动出新的用于填充光敏树脂的空隙,即执行如下的步骤。 If desired injection operation and the formed article moving stereoscopic three-dimensional structure, it is necessary for a plurality of times continuously in a liquid state photosensitive resin is used to fill the voids of a new photosensitive resin, i.e., perform the following steps.

[0034] 将已固化成型的光敏树脂远离光源后,由于成像部件保持位置不变,在成像部件与固化成型的成型体之间空出新的间隙,该间隙需要小于流体状态的光敏树脂的固化深度,“固化深度”是在一定光照情形下,流体状态的光敏树脂能够发生聚合反应的深度,如果大于该深度,将导致远离光源侧的光敏树脂不能很好地发生聚合反应或者聚合反应进行不完全,使成型体不能达到目标的固化(硬化)程度。 Curing the photosensitive resin [0034] The photosensitive resin cured after molding away from the light source, since the imaging member holding the same position, between the imaging member and the cured molded body molded of a new empty gap which is less than required in a fluid state depth, "depth of cure" is the light in certain circumstances, the photosensitive resin in the fluid state capable of generating the depth of the polymerization reaction, if more than this will lead to the light source side away from the photosensitive resin of the polymerization reaction is not well performed, or the polymerization reaction does not occur complete, the molded body can not achieve curing (hardening) the degree of target.

[0035] 步骤S304:向所述承载体内注入新的流体状态的光敏树脂填充所述第一间隙; [0035] Step S304: the first gap is filled photosensitive resin to said carrier body into a state of new fluid;

[0036] 步骤S305:使用与所述承载体位于所述成像部件异侧的光源照射所述成像部件,以便透过所述成像部件展现的二维图像所在区域或二维图像之外的成像部件范围内的其他区域使新注入的流体状态的光敏树脂固化成型; [0036] Step S305: using the imaging member body is located outside the light source of the imaging member opposite side of the imaging member, said imaging member so as to show through the two-dimensional image or a two-dimensional image bearing Area other areas within the range of the fluid injected new state photosensitive resin cured molded article;

[0037] 步骤S306:判断光敏树脂的固化成型是否达到预设高度,如果是,则结束流程;如果否,则返回步骤S303。 [0037] Step S306: determining whether or not the cured photosensitive resin molding reaches a preset height, and if so, the process ends; if not, returns to step S303.

[0038] 通过多次执行上述S303〜S305的步骤,多个单层的二维成形体将粘附累积成一个立体三维结构的目标成型体。 [0038] By repeatedly performing the above steps S303~S305, a plurality of two-dimensional monolayer adhered molded into a target molded article, the accumulated stereoscopic three-dimensional structure.

[0039] 上述装置或方法实施例叙述了光源和承载流体状态的光敏树脂的承载体位于成像部件异侧的情形,实际上,基于现实需要,可以对这种组成架构进行适当变形,获得其他组成结构的光固化快速成型装置。 Carrier photosensitive resin Example [0039] The light source apparatus or the method described and the carrier fluid state is positioned opposite side to the case of the imaging member, in fact, based on practical needs, may be appropriately modified architecture of such a composition, the other components to obtain light-cured structure rapid prototyping apparatus. 比如,该是示出了再一种光固化快速成型装置实施例的组成结构,该实施例与上述装置实施例不同的是光源与承载体位于成像部件的同侧,这种情况下,光固化快速装置还包括反射部件,用于反射所述光源的光,使反射的光可经过所述成像部件照射到流体状态的光敏树脂,这样同样能够实现本申请的发明目的。 For example, the re is a diagram showing an optical stereolithography apparatus configuration example of the composition of embodiment, different embodiments of the above-described embodiment, the light source device embodiment of the imaging member to the carrier body on the same side, in this case, the photocurable Quick apparatus further includes reflecting means for reflecting the light source, the reflected light may be irradiated through said imaging member to a photosensitive resin in a fluid state, so that the same object can be achieved in the application of the present invention. 同样地,基于这种类型的光固化成型装置,参见图4,其工作过程包括:[0040] 步骤S401:向承载流体状态的光敏树脂的承载体内注入流体状态的光敏树脂,在展现二维图形的成像部件上展现二维图形,所述成像部件展现的二维图形所在区域与二维图形之外的成像部件范围内的其他区域的透明状态相反; Similarly, based on the type of stereolithography apparatus, see FIG. 4, which work process comprising: [0040] Step S401: the photosensitive resin in a fluid state is injected into the photosensitive resin onto a carrier carrying a fluid state, in the two-dimensional pattern to show show two-dimensional pattern on the imaging member, opposite to the transparent state in the other areas outside the imaging range of the imaging member exhibits two-dimensional pattern member area of ​​the two-dimensional pattern;

[0041] 步骤S402:使用与所述承载体位于所述成像部件同侧的光源经过反射部件照射所述成像部件,以便经反射部件反射的光透过所述成像部件展现的二维图像所在区域或二维图像之外的成像部件范围内的其他区域使流体状态的光敏树脂固化成型。 [0041] Step S402: using the carrier of said image forming member located on the same side of the light source via the reflecting member of said imaging member, so that the light reflected by the reflective member through the region where the two-dimensional image of the imaging member exhibited other regions within or outside the range of the imaging member two-dimensional image of the fluid state of the photosensitive resin cured molding.

[0042] 同样地,在需要成型的目标成型体为立体三维结构时,也可以通过增加移动步骤使已固化成型的薄层与成像部件之间的产生新的间隙,从而在该间隙内注入新的流体状态的光敏树脂,制作新的薄层,多个薄层自动粘附在一起形成立体三维结构的成型体。 [0042] Similarly, when the desired molded bodies needed for molding three-dimensional three-dimensional structure, may be produced by increasing the step of moving the sheet between the imaging member and the cured molded new gap, so as to inject new in the gap the photosensitive resin in a fluid state, to create a new sheet, self-adhesive together to form a plurality of thin molded three-dimensional three-dimensional structure.

[0043] 实际上,基于上述改进光固化快速成型装置的思路,本领域技术人员还可以得到上述涉及装置的更多变形形式,只要提供的光源能够透过明暗状态不同的二维图形照射到流体状态的光敏树脂使其固化成型,即可实现本申请的发明目的。 [0043] In fact, based on the idea of ​​improving the photo-curable rapid prototyping apparatus, those skilled in the art can also be obtained in the form of the above-described modification relates more means, as long as the light source can be provided through the shading state of different two-dimensional pattern is irradiated to the fluid the photosensitive resin cured state is formed, to achieve the object of the present invention of the present application.
