背景技术 BACKGROUND

近年来,已经发展了许多种不同的三维模型快速制造技术来用于工业应用。 In recent years, has developed a number of different types of three-dimensional model of rapid manufacturing technology for industrial applications. 这些实体成像技术有时称为快速原型设计制造(“RP&M”)技术。 These entities imaging techniques are sometimes referred rapid prototyping manufacturing ("RP & amp; M") techniques. 通常,快速原型设计制造技术使用表示待形成目标横截面的切片数据组,而从工作介质分层构建三维目标。 Generally, the use of rapid prototyping manufacturing technology, said to be the formation of a cross-section of the target slice data sets, and build three-dimensional object from a working medium stratification. 通常,最初由计算机辅助设计(CAD)系统提供目标表示。 Typically, initially provided by computer-aided design (CAD) system, said the goal.

当前最通用的RP&M技术是光固化成型技术(Stereolithography),这是从CAD数据生成三维目标的第一个在商业上成功的实体成像技术。 The most common RP & amp; M technology is a light curing technology (Stereolithography), which is the goal of generating a three-dimensional CAD data from the first entity in imaging technology commercially successful. 光固化成型技术可定义为以下这样的技术,其通过在工作表面对各材料层的选择性曝光以固化和粘附目标的连续的各层(即,薄层),而从流体状材料自动制成三维目标。 The photocurable molding technology can be defined as following this technique by which the working surface of each material layer is selectively exposed to light to cure and adhesion target of continuous layers (i.e., thin layer), and a fluid-like material from automatic preparation into a three-dimensional object. 在光固化成型技术中,表示三维目标的数据输入为或转换成表示目标各横截面的二维层数据。 In the photo-curable molding technique, represents three-dimensional object data input is converted into a representation, or a two-dimensional layer data of each cross section of the target. 最常使用计算机控制紫外(UV)激光束辐射来根据二维层数据而连续地形成材料层并将其选择性地转换或固化(即,硬化)成连续薄层。 The most commonly used computer controlled ultraviolet (UV) laser beam radiation according to a two-dimensional layer data continuously forming material layer and selectively convert or cure (i.e., cured) into successive thin layers. 在转换期间,将连续薄层粘合到先前形成的薄层,以允许三维目标的整体形成。 During the conversion, the successive thin layers bonded to the previously formed thin layer, to allow the overall three-dimensional object is formed. 这是添加工艺。 This is added processes. 近来更多的设计是利用可见光来启动聚合反应,以使通常称为树脂的光聚合物构建材料固化。 More recent designs is the use of visible light to initiate the polymerization reaction, so that the photopolymer build material is typically referred to as resin curing.

光固化成型技术代表了一种无需模具制造就快速制作复杂或简单部件的前所未有的方法。 Light-curing technology represents an unprecedented way to quickly create mold without complex or simple parts. 由于该技术依靠使用计算机产生其横截面图案,所以存在到CAD/CAM的固有数据链路。 Since this technique relies on the use of a computer-generated pattern of its cross-section, there is a problem inherent to the data link of CAD / CAM. 这些系统已经遇到了其不得不克服的有关收缩、卷曲和其它变形以及分辨率、精度的困难,还有在生产特定目标形状中的困难。 These systems have been encountered regarding its contraction had overcome, curl and other variants as well as the resolution of difficulties accuracy, as well as difficulties in the production of a specific target shapes. 尽管光固化成型技术显示出其本身是形成三维目标的有效技术,但是随着时间的发展,还发展了其它实体像技术,以解决光固化成型技术中固有的困难,并提供其它RP&M优点。 Although the light-curing technology exhibits itself is an effective technique to form a three-dimensional object, but over time, but also the development of other entities like technology to solve the difficulties of light curing technology inherent and provide other RP & amp; M Advantages .

这些替代技术连同光固化成型技术一起共同地称为实体自由制造(solid freeform fabrication)技术或实体成像技术。 These alternative technologies, along with light-curing technology together referred to as solid freeform fabrication (solid freeform fabrication) imaging techniques or entity. 它们包括分层目标制造(LOM)、激光熔结、熔融沉积成型(FDM)和各种基于喷墨的系统,这些基于喷墨的系统输送液体粘合剂至粉末材料或输送通过温度变化或光电硬化而固化的构建材料。 They include stratification target manufacturing (LOM), laser sintering, fused deposition modeling (FDM) and a variety of inkjet-based systems, these delivery systems based on inkjet or liquid adhesive to the powder material transport by temperature changes or photoelectric Construction material is hardened and cured. 最近,使用数字光处理技术的一种技术利用可见光来启动聚合反应,以使通常称为树脂的光聚合物构建材料固化。 Recently, a technology using digital light processing technology using visible light to initiate the polymerization reaction, so that the photopolymer build material is typically referred to as resin curing. 这些附加技术每个都改善了精度、构建速度、材料特性、降低成本和构建目标的外观中的一个或多个方面。 Each of these additional techniques to improve the accuracy, building speed, material properties, reduced cost, and appearance of the target construct of one or more aspects.

所有成功的实体成像技术或自由制造技术必须形成接近全密度(full density)或没有不期望有的孔隙或气孔。 All successful imaging technology entities or free manufacturing techniques must be formed close to full density (full density) or no undesirable voids or pores. 气孔引起的孔隙会在要构建的目标中产生不连续性和脆弱点,并且无法精确地复制从CAD表示产生的目标的三维方面。 Stomatal pores will produce discontinuities and vulnerabilities in target to build, and can not accurately replicate represents the target generated from the three-dimensional aspects of CAD. 在使用中间转移工艺分层布置可固化液体树脂的技术中,这个问题尤其严重。 In the intermediate transfer process layered arrangement curable liquid resin technology, this problem is particularly acute. 中间转移表面的使用减少了必须从完成部件去除的多余树脂的量,并消除了构建大桶或大型树脂容器的需要,其中可固化液体树脂从中间转移表面转移至支撑台或材料的底层。 An intermediate transfer surface of the member to be used to reduce the amount of excess resin is removed from the completion of, and eliminates the need to build a vat or large container of resin, wherein the curable liquid resin is transferred from the intermediate transfer surface to a support table or the underlying material. 这确实消除了超出构建所需部件所必需量的附加树脂的成本。 This really eliminates the cost exceeds the additional resin components required to build the necessary amounts. 但是,它增加了在形成材料横截面时,对于所转移液体树脂的可靠且一致的层厚以及对于用作转移表面的环形带的定轨和张紧的需求。 However, it increases the cross-section of the material at the time of forming, the transfer of the liquid resin reliable and consistent layer thickness is used as transfer surface and for the orbit determination of the endless belt and tensioning requirements.

另外,现有实体自由制造方法尽管有了很大的提高,但是仍未实现在短的构建时间内制造高精度且外观吸引人的三维目标的真正低成本系统。 In addition, the existing method of manufacturing entity in spite of freedom has been greatly improved, but has yet to achieve true manufacturing cost systems with high accuracy and attractive appearance of three-dimensional objects in a short build time.

在本发明的设计中,通过以生成精确反映CAD表示的三维目标的方式结合使用数字成像投射或激光扫描来利用低成本实体成像技术中的材料转移技术和设备,同时始终施加均匀厚度的可固化液体材料来形成三维目标,可解决这些问题。 In the design of the present invention, by way of three-dimensional object to generate accurately reflect the CAD representation of the combined use of digital imaging projection or laser scanning technology using low-cost solid imaging material transfer techniques and equipment, while always applying a uniform thickness of the curable liquid material to form a three-dimensional object, to resolve these issues.

见图3,数字光投射仪是辐射源44,在对支撑台53上形成的三维目标的横截面进行曝光时,该辐射源44将具有选择来照射的像素的图像投射在处于环形带11上侧运行部的下方的镜系统41上,这在图4中更加清楚地示出。 Figure 3, a digital light projection device is a radiation source 44, when the three-dimensional object on a cross-section formed on the support table 53 is exposed, the radiation source 44 having an image projected on the irradiation of the pixels selected to be in the endless belt 11 in below the mirror system on the side running portion 41, which is more clearly shown in Figure 4. 如图5中实施例所示,支撑台53通过步进电机58升降。 5, in the embodiment shown, the support table 53 by a stepping motor 58 up and down. 在图1-4的实施例中,使用一对步进电机58来将螺纹丝杠59以及在成像系统10相对两侧的导轨60向上驱动。 In the embodiment of Figure 1-4, using a pair of stepper motor 58 to the lead screw 59 and the imaging system 10 on opposite sides of the guide rail 60 is driven upward. 通过适当紧固在系统机架上的导轨锚板61和62,将导轨60保持在适当的位置中。 By appropriately fastened to the system frame rail anchor plates 61 and 62, the rail 60 is held in the appropriate position. 支撑台装配杆54被紧固到各个步进电机58。 Support platform assembly bar 54 is fastened to each stepper motor 58.

如图1-4中所清楚示出的,支撑台装配杆54延伸穿过分别在机架端板35、45内的槽55、56。 1-4 as clearly shown in Fig support platform assembly bar 54 extends through each end plate 35, 45 in the rack grooves 55, 56. 这使支撑台装配杆54能够通过步进电机58移动,以升降支撑台53。 This allows the lever assembly support base 54 can move by the stepping motor 58 to lift the support table 53. 这使已形成的横截面层与从树脂或可固化液体介质料筒分配器13沉积在环形带11上的树脂或可固化液体构建材料层47相接触,该料筒分配器13是构建材料供给料筒组件12的一部分。 This allows the cross-sectional layer is formed from a resin or curable with a liquid medium cartridge dispenser 13 is deposited on the endless belt 11 or the resin curable liquid build material layer 47 contacting the cartridge dispenser 13 is a building material supply part of the barrel assembly 12. 简要参见图8,料筒分配器13包括可固化液体介质的树脂容器以及分配口或分配通道45,可固化液体构建材料通过该分配口或分配通道45涂覆到带11上。 Referring briefly to Figure 8, the cartridge dispenser 13 includes a resin curable liquid medium container and the dispensing opening or the distribution channel 45, the curable liquid build material is applied by the dispensing port 45 or the channel assigned to the belt 11.

图1和2示出了总体由标号27表示的驱动辊支架。 Figures 1 and 2 shows the general by the reference numeral 27 denotes a driving roller bracket. 驱动辊14、15可旋转地安装在垂直机架组件16、18之间。 Driving rollers 14, 15 rotatably mounted between the vertical frame assembly 16, 18. 驱动电机22、24安装到垂直机架组件18上,并驱动地连接到驱动辊14、15上。 Drive motor 22, 24 mounted to the vertical frame assembly 18, and drivingly connected to the drive rollers 14, 15 on. 驱动辊垂直机架组件25附装到驱动电机的末端。 Vertical Rack drive roller assembly 25 is attached to the end of the drive motor. 带定轨电机26在带11绕着辊14、15、19和20旋转时控制带11的定轨,并且反向与驱动电机22和24相对。 Orbit motor 26 with the belt 11 in 14-15 and 20 to rotate around the roll control with fixed rails 11, and the reverse with the drive motor 22 and 24 relative. 如图2中清楚所示,电机轴28从电机26延伸穿过机架组件25。 Figure 2 clearly shows, the motor shaft 28 extends from the motor 26 through the frame assembly 25. 带定轨控制臂29附装到轴28的末端。 Orbit with the control arm 29 is attached to the end of the shaft 28. 定轨控制臂机架组件30连接机架组件16和18,并包括用来安装驱动辊支架27的枢轴附件31(如图4和6简要所示)。 Orbit control arm assembly 30 is connected to the chassis frame assemblies 16 and 18, and includes a pivot bracket for mounting the drive roller 27 of Annex 31 (4 briefly shown and Figure 6). 如图1和2中所示,在机架组件30上安装有左边缘带定轨光学传感器33和右边缘带定轨光学传感器37。 As shown in Figures 1 and 2, the assembly 30 is mounted on the frame with the left edge of the orbit determination of the optical sensor 33 and the right edge of the optical sensor 37 with Orbit.

图6是驱动辊支架27的俯视示意图。 Figure 6 is a schematic plan view of the drive roller 27 of the stent. 连同垂直机架组件16、18和25一起示出了驱动辊14、惰辊19和环形带11(以虚线的形式)。 Together with the vertical frame assembly 16, 18 and 25 are shown together with the driving roller 14, idler roller 19 and endless belt 11 (in the form of a broken line). 驱动辊支架上的枢轴附件31与机架端板35上的枢轴39之间附装有安装臂36。 Pivot accessory drive roller 31 and the pivot bracket on the frame 35 is provided between the end plates attached to the mounting arm 36 39. 枢轴附件31的枢轴点从附件31的中心偏移一小段距离。 Pivot attachment pivot point 31 of Annex 31 of the offset from the center a short distance. 气缸32安装成穿过端板35,使得缸塞34与图1和2中定轨控制臂机架组件30背面上的枢轴附件31的背部相接触。 Cylinder 32 is mounted through the end plate 35, so that the back of the cylinder plug 34 pivot attachment 30 on the back surface 31 is in contact with a fixed rail and the control arm 2 chassis unit in Fig. 当给图6的气缸32增压时,缸塞34通过枢轴附件31在驱动辊支架上施加力。 When the cylinder 6 to 32 pressurized, the cylinder 34 the plug 31 exerts a force on the driving roller bracket by a pivot attachment. 整个驱动辊支架绕着枢轴39运动,该运动使驱动辊14、15与惰轮19、20之间的距离伸长,由此当缸塞34伸出时在环形带11上施加张力,或者当缸塞34缩回时缩短该距离从而减小张力。 Entire drive roller holder 39 about the pivot movement, the movement between the driving rollers 14, 15 and idler 19, 20 distance is extended, whereby when the cylinder plug 34 extending in annular upper tension band 11 is applied, or shorten the distance so as to reduce tension when the cylinder plug 34 is retracted. 这样,可在环形带11上保持所需的张力。 Thus, in the ring 11 to maintain the desired tension on the belt.

如图8中所示,当带11垂直向下行进通过构建材料料筒分配器13中的分配口或分配通道45时,带11中的张力控制着涂覆到环形带11的可固化液体构建材料47的厚度。 8, when the belt 11 travels vertically downwardly through the dispenser 45 when the cartridge constructing material in the dispensing opening or the distribution channel 13, the belt 11 controls the tension applied to the endless belt 11 of FIG curable liquid Construction The thickness of the material 47. 分配口或分配通道45从料筒分配器13之中的容器(未示出)向带11的表面51供应材料。 The dispensing opening or the distribution channel 45 from the barrel 13 into the dispenser container (not shown) to the surface 51 of the belt 11 of the supplied material. 料筒分配器13具有分别位于通道45上方和下方的平坦部分46和48,并且在底部具有大半径弧形部分49,以便在带被沿其路径绕着辊14、15、19和20驱动时,对带11的覆层表面51上的构建材料47提供间隙。 Cartridge dispenser 13 having channels 45 which are located above and below the planar portion 46 and 48, and has a large radius arc in the bottom portion 49, so that the belt is along its path around the driven rollers 14-15 and 20 for building material coating the surface 51 with 11 on 47 to provide clearance. 可选择地,部分49可成锐角或直角,以提供所需的间隙。 Alternatively, portion 49 may be an acute angle or at right angles, to provide the desired clearance. 当带11运动通过通道45时,在通道45的底边50产生流体楔,通过流体楔效应在带11上涂覆均匀的覆层,使得张力越大,覆层就越薄。 When the belt 11 moves through channel 45, channel 45 in the bottom edge of the wedge 50 to produce, by the wedge effect of the belt 11 is coated uniformly coating, such that the greater the tension, the thinner the coating. 料筒分配器13可具有与其一体或与其远离的液体构建材料47的容器。 Cartridge dispenser 13 may have integral therewith or remote from the liquid build material 47 in the container. 如果与分配器13远离,则该容器与分配器13流体连通,使得该容器可与料筒分配器13分开更换。 If away from the dispenser 13, the dispenser 13 is in fluid communication with the container so that the container can be used with the dispenser 13 replacement cartridge separately.

覆层厚度由适当的传感器监测,如图案识别装置。 Coating thickness by monitoring the appropriate sensor, such as a pattern recognition device. 如果覆层厚度太厚,则缸塞34将缓慢地伸出,以提高带11的张力并减小流体楔,从而使覆层变薄,直到得到正确厚度的覆层。 If the coating thickness is too thick, the cylinder plug 34 will slowly extend, in order to improve the tension band 11 and reduces the wedge, so that the coating thinner until the correct thickness coating. 或者,如果覆层太薄,则缸塞34将缩回,以降低带11的张力并从而增大流体楔,使覆层变厚直到达到所需的厚度。 Alternatively, if the coating is too thin, the cylinder plug 34 will be retracted to reduce the tension of the belt 11 and thereby increasing the fluid wedge so that coating thicker until the desired thickness. 覆层厚度可控制到0.002英寸以用于较快的成像,或者可控制到0.001英寸以用于较慢的成像。 Coating thickness can be controlled to .002 inches for faster imaging order, or may be controlled to .001 inches for slower imaging. 气缸32可以对带11施加每平方英寸10至20磅之间的力,以确保带被绕着辊14、15、19和20张紧。 Power cylinder 32 between 10-20 pounds per square inch can be applied to the belt 11, to ensure that the belt is tensioned around rollers 14-15 and 20. 还可使用任意其它有效装置来在带11上施加压力,例如电磁阀、弹簧或其它适当的机械系统。 Any other effective means may be used to exert pressure on the belt 11, such as a solenoid valve, spring or other appropriate mechanical system. 无论通道45具有倾斜底边50还是直的或圆的底表面,都可有效地产生流体楔。 Whether the channel 45 having an inclined bottom edge 50 or a straight or rounded bottom surface, the wedge can be efficiently generated. 流体楔的效率随着很多因素的变化而变化,这些因素包括:可固化液体构建材料47的粘度、构建材料47与带11之间的表面张力、料筒分配器13中液体构建材料47的压头(pressure head)、分配通道45的开口的高度、平坦部分46和48的长度、以及带11在绕着辊14、15、19和20运行经过通道50时带11的速度和张力。 The efficiency of the wedge varies by many factors vary, these factors include: the viscosity of the curable liquid build material 47, 47 and the building surface tension of the material between the belt 11, the liquid cartridge dispenser 13 constructed of material 47 pressure height of the head (pressure head), the distribution channel openings 45, 46 and the flat portion 48 of a length, and a belt 11 around the rollers 14-15 and 20 run through the passage 50 when the speed and tension of the belt 11.

现在参见图6和图7,带定轨电机26在定轨控制臂29上施加旋转力。 Referring now to FIG. 6 and 7, with a fixed rail motor 26 rotational force exerted on an orbital control arm 29. 控制臂29经由任何适于使驱动辊支架27枢转的连接件(例如磁球38)而附装到安装臂36例如。 The control arm 29 via any suitable driving roller holder 27 pivotally connecting member (e.g., magnetic balls 38) and attached to the mounting arm 36, for example. 球38位于控制臂29的槽和安装臂36的埋头孔内。 38 is located in the groove and ball control arm mounting arm 29 countersunk hole 36. 如果电机22施加顺时针的旋转力,则控制臂29将磁球38推入安装臂36,迫使驱动辊支架27离开安装臂36。 If the motor 22 is rotated clockwise force is applied, the control arm 29 pushes the magnetic ball 38 into the mounting arm 36, forcing the drive roller holder 27 away from the mounting arm 36. 相反,如果电机22施加逆时针的旋转力,则控制臂29远离安装臂36,磁力将支架推向安装臂36。 Conversely, if the motor 22 rotates counterclockwise force is applied, the control arm 29 away from the mounting arm 36, the magnetic force will push the bracket mounting arm 36. 这使驱动辊支架绕着图6的枢轴点31旋转。 This allows the drive roller holder 31 is rotated about pivot point 6 of FIG. 因此,驱动辊14和15旋转以转动带11。 Therefore, the driving roller 14 and 15 is rotated to rotate the belt 11. 如图1和图2中所示,如果驱动辊支架27顺时针旋转,则带11左转,而驱动辊支架27逆时针旋转时,带11右转。 As shown in Figure 2 and 1, if the drive roller holder 27 is rotated clockwise, the belt 11 to turn left, and the drive roller holder 27 is rotated counterclockwise, with a 11 turn right. 再参见图2,定轨传感器33和37相距一段距离,使得带11的宽度刚好分别在传感器33和37的边缘上方延伸。 Referring again to Figure 2, the sensor 33 and the fixed rail 37 at a distance, so that the width of the belt 11 extending respectively just in the sensor 33 and the upper edge 37. 传感器33和37为感测带11的存在的光学传感器。 Sensor 33 and the optical sensor 37 to sense the presence of tape 11. 在操作中,当驱动带11时,带11将横向平移,直到其露出传感器33或37之一。 In operation, when the drive belt 11, belt 11 will translate laterally until it is exposed, or one of 37 sensor 33. 然后,定轨电机22上的力将反向,并且带11将平移,直到露出另一个传感器,该过程再次反向。 Then, the force on a given track motor 22 will reverse, and with 11 pan, until exposing another sensor, reverse the procedure again. 这样,带11不断地在一小段距离中横向地来回移动。 Thus, the belt 11 constantly in a short distance laterally back and forth movement.

在辐射光源44与覆有可固化液体构建材料47的带11上的对象区域之间设有适当的副像素图像位移装置(未示出)。 Between the radiation source 44 and the belt 11 is coated with a target region on the curable liquid build material 47 is provided with appropriate sub-pixel image displacement means (not shown). 通过照射所选像素来曝光图像横截面而产生要形成的三维目标的横截面的固化部分。 Exposure by irradiation of the selected pixels to generate cross-sectional images cured portions of the cross-section of the three-dimensional object to be formed. 可选择地,副像素图像位移装置可以是具有位于环形带11运行部之外的像素移位装置的镜子,或者副像素图像位移装置可在单个组件中组合有镜子和像素移位装置。 Alternatively, the sub-pixel image displacement device may be a pixel having a mirror portion located on the endless belt 11 running outside the shifting means, or the sub-pixel image displacement device can be combined in a single component with a mirror and pixel shifting device.

在本发明的实施中,可使用能够响应于施加适当形式的能量激励而固化的任何适当的流体构建材料。 In the embodiment of the present invention may be used to respond to any suitable fluid suitable form of energy is applied to the excitation cured building material. 已知许多种可通过用UV辐射或可见光照射而变为固态聚合塑料的液态化学物质。 Known that many species may be obtained by irradiation with UV radiation or visible light into the solid state polymerization of a liquid plastic chemicals. 在下面的表格I中示出了在实施本发明中可以使用的适合的可见光可固化的光聚合物。 In the following Table I shows the light in a visible light in a polymer suitable for the practice of this invention may be used in curable. 当使用BenQ PB7220投射仪时,该配方展示出优异的分辨率和感光速度。 When using a projector BenQ PB7220, this formulation demonstrated excellent resolution and photographic speed. 所产生的部件显示出具有平衡硬度和韧性的突出的生坯强度(green strength)。 Member generated exhibits outstanding green strength with balanced stiffness and toughness (green strength).

表I Table I

可向配方中加入添加剂以提高从透明传送装置分离的能力,这些添加剂例如硅丙烯酸脂材料。 Additives may be added to the formulation to improve the capability of the apparatus separated from the transparent transmission, these additives, such as silicon acrylic resin material.

在操作中,构建三维目标的数据从CAD站(未示出)发送到柔性传送实体成像系统,该CAD站将CAD数据转换成适当的数字层数据格式并将其输入到计算机控制系统(也未示出),在该计算机控制系统中,通过算法操纵目标数据来优化数据以给数字光投射仪提供开启/关闭指令。 In operation, data to build three-dimensional object from a CAD station (not shown) is sent to the transmitting entity a flexible imaging system, the CAD station converts the CAD data to a suitable digital layer data format and input to the computer control system (also not shown), the computer control system to optimize data manipulation algorithms target data to the digital light projection instrument provides on / off commands. 通过由产生横截面数据的切片程序处理的CAD数据得到实体成像层数据。 CAD data generated by the cross-sectional data slice imaging procedures to get physical layer data. 然后,通过适当的控制器,例如微处理器或计算机,对横截面数据应用算法以对数字光投射仪提供指令,以便照射所形成横截面中位于三维目标边界内的图像中的所选像素。 Then, by a suitable controller, such as a microprocessor or computer, to cross-sectional data application algorithms to the digital light projector in providing instructions to irradiation cross-section located within the boundaries of the three-dimensional object in the selected pixels forming the image. 可使用适当的像素移位图像位移装置,以提高所生成横截面的分辨率和边缘平滑度。 Use the appropriate pixel shifting image displacement device, in order to improve the resolution of the generated cross-section and edge smoothness.

在完成层的成像后,降低支撑台53。 After the completion of the image forming layer, lowering the support table 53. 由于固化图像现在粘在带11与支撑台53上,所以带11被支撑台53向下拉成弓形,直到将部件层从带11剥离。 Because the image is now stuck in the curing of the support band 11 on stage 53, so 11 is a support table with 53 to drop down into a bow, until the part layer peeled from the belt 11. 然后带11返回其伸直的状态。 Then with 11 returns to its straight state. 承载构建材料47的辐射透明带11从形成待形成三维部件横截面的构建材料的暴露固化层剥离,且其间不会有水平运动。 Carrying a radiation transparent build material 47 is exposed with a cured layer peeling member 11 to be formed from a three-dimensional cross-section of the build material, and there will be no horizontal motion therebetween. 辐射透明带11的柔性使得分离能够以剥离作用的形式发生,因为分离力与构建材料47的曝光区域的宽度成比例而与曝光构建材料的总面积成反比,如同在非柔性平面的情形中所发生的那样。 Flexible radiation transparent belt 11 enables the separation can be in the form of peeling action occurs, because the separation force inversely proportional to the width and the Construction of the exposure area of the material 47 with the total area of the exposed build material, as in the case of a non-flexible in the plane happen to be.

选择部件在构建支撑台53上构建的基底,以使该部分对该基底的粘合强度大于其对带11的粘合强度。 Selection means on the support table 53 in the construction of built substrate, so that the portion of the substrate is greater than the adhesive strength of the adhesive strength of the tape 11. 基底材料应当是透光的、柔性的,并且易于附装到构建支撑台53上。 The base material should be light transmissive, flexible, and easy to build a table attached to the support 53. 其可为细砂纸或类似的材料以提供握持性,但是更优选地是多孔材料,例如硅树脂粉(ground silicone),该多孔材料允许所有湿的未固化材料从部件流走以使部件尽可能保持干燥。 Which may be a fine sandpaper or similar material to provide grip properties, but more preferably is a porous material, such as silicon resin powder (ground silicone), the porous material allows any wet, uncured material to flow away from the component parts do so may remain dry.

随着部件的增大,各新层粘合到位于其下方的固化构建材料层上。 With the increase of parts, each new layer beneath the cured adhesive in place thereon construct the upper material layer. 一旦支撑台处于其最低位置,就沿行进方向21驱动带来用构建材料47重新涂覆带11。 Once the support platform is in its lowest position, bring along the direction of travel for driving 21 47 11 re-coated with building materials. 为建立层厚一致的构建材料,带11将被驱动约12”至18”。 Construction materials for the establishment of a consistent thickness, belt 11 will be driven approximately 12 "to 18." 然后支撑台53上升至适当的位置。 Support table 53 is then raised to the appropriate location. 由于现在在支撑台53上具有0.001”厚的部件切片,所以支撑台53升入比前一个低0.001”的位置,使得现在部件顶部与带11的表面51上的构建材料47的覆层紧密接触。 Because now has support table 53 on 0.001 "thick slices member, the support table 53 so promoted lower than the previous one 0.001" position, so that now the cladding material of construction of the top member 47 and the upper surface 51 of belt 11 in close contact . 实际上,由步进电机58来控制该定位,该步进电机58以非常精确的运动并且可重复的方式升降支撑台53。 In fact, by the stepper motor 58 to control the position, the stepping motor 58 in a very accurate and repeatable manner the motion riser support table 53. 例如,如果在每次曝光之后电机58将支撑台向下移0.500”,但只向上移0.499”,则它们将总是补偿每次循环所产生的0.001”。既然带11已经被重新涂覆并且支撑台53处于适当的位置,于是就投射部件的下一切片,并且该过程继续直到完成部件。 For example, if the motor 58 after each exposure to the support table down 0.500 ", but move up only .499", they will always compensate for each 0.001 generated cyclic. "Since the belt 11 has been re-coated and support table 53 is in the proper position, then the next slice to the projection member, and the process continues until completion member.
