Description
本發明係關於一種3D(立體)列印成型技術,特別是有關於一種製造三維物體的光固化立體造型裝置用之光固化材料容器及其製作方法。The present invention relates to a 3D (three-dimensional) printing molding technology, in particular to a light-curing material container used in a light-curing three-dimensional modeling device for manufacturing three-dimensional objects and a manufacturing method thereof.
近年來,隨著科技的日益發展,許多利用逐層建構模型等加成式製造技術(additive manufacturing technology)來建造物理三維(three dimensional,3D)模型的不同方法已紛紛被提出。一般而言,加成式製造技術是將利用電腦輔助設計(computer aided design, CAD)等軟體所建構的3D模型的設計資料轉換為連續堆疊的多個薄(准二維)橫截面層。於此同時,許多可以形成多個薄橫截面層的技術手段也逐漸被提出。舉例來說,列印裝置的列印模組通常可依據3D模型的設計資料所建構的空間座標XYZ在基座的上方沿著XY平面移動,從而使建構材料形成正確的橫截面層形狀。In recent years, with the increasing development of science and technology, many different methods of building physical three dimensional (3D) models using additive manufacturing technology such as layer-by-layer model building have been proposed. Generally speaking, additive manufacturing technology converts the design data of a 3D model constructed by software such as computer aided design (CAD) into multiple thin (quasi-two-dimensional) cross-sectional layers that are continuously stacked. At the same time, many technical methods that can form multiple thin cross-sectional layers have gradually been proposed. For example, the printing module of the printing device can usually move above the base along the XY plane based on the spatial coordinates XYZ constructed by the design data of the 3D model, so that the construction material forms the correct cross-sectional layer shape.
現今所採用的快速成型技術也各異,目前業界所採用之快速成型技術主要包含下述幾種技術:膠水噴印固化粉末成型(Color-Jet Printing,CJP,或稱Binder Jetting)技術、熔融沉積成型(Fused Deposition Modeling,FDM)技術、雷射燒結液態樹脂成型(Stereo Lithography Apparatus,SLA)技術、紫外光固化液態樹脂成型(Multi-Jet Modeling,MJM)技術、或是雷射燒結固態粉末成型(Selective Laser Sintering,SLS)技術等等,但不以此為限。The rapid prototyping technologies used today are also different. The rapid prototyping technologies currently used in the industry mainly include the following technologies: Color-Jet Printing (CJP, or Binder Jetting) technology, fused deposition Molding (Fused Deposition Modeling, FDM) technology, laser sintered liquid resin molding (Stereo Lithography Apparatus, SLA) technology, UV-curable liquid resin molding (Multi-Jet Modeling, MJM) technology, or laser sintered solid powder molding ( Selective Laser Sintering, SLS) technology and so on, but not limited to this.
立體影像掃描技術與立體顯示技術皆為目前3D(Three-dimensional)列印技術的重點,掃描欲列印的物件,並產生適當的立體影像資料作為3D列印的影像源,並藉由電腦及印表機的輔助,將立體影像的內容列印出實體的3D模型。因此,掃描物件及立體影像產生的技術會關係到是否能列印出精確的3D模型。以光固化立體成型(Stereolithography)的立體造型裝置為例,其為透過光源固化建構材料而形成立體物件的技術,列印模組適於浸入盛裝在樹脂槽中的液態成型材中,而光源模組在XY平面上照射作為建構材料的液態成型材,以使液態成型材被固化,並堆疊在一移動平台上。如此,藉由移動平台沿著軸向Z逐層移動,即可使液態成型材逐層固化並堆疊成立體物件。需說明的是,當光源配置於樹脂槽下方時,剛經由光源固化成型的列印中物件會黏著於樹脂槽的底部。為了使液態成型材能夠繼續逐層固化並堆疊,立體列印裝置需要透過擺動樹脂槽來將列印中的立體物件與樹脂槽底部分離。Both stereoscopic image scanning technology and stereoscopic display technology are the focus of current 3D (Three-dimensional) printing technology. The object to be printed is scanned, and appropriate three-dimensional image data is generated as the image source for 3D printing. With the aid of a printer, the content of the three-dimensional image is printed out as a physical 3D model. Therefore, the technology of scanning objects and generating 3D images will be related to whether accurate 3D models can be printed. Take the stereolithography device for stereolithography as an example. It is a technology of curing construction materials through a light source to form a three-dimensional object. The printing module is suitable for being immersed in the liquid molding material contained in the resin tank, and the light source mold The group irradiates the liquid molding material as the construction material on the XY plane so that the liquid molding material is solidified and stacked on a moving platform. In this way, by moving the moving platform layer by layer along the axis Z, the liquid molding material can be solidified layer by layer and stacked into a solid object. It should be noted that when the light source is disposed under the resin tank, the printed object that has just been cured by the light source will adhere to the bottom of the resin tank. In order to enable the liquid molding material to continue to solidify and stack layer by layer, the three-dimensional printing device needs to swing the resin tank to separate the three-dimensional object being printed from the bottom of the resin tank.
樹脂槽為用來盛裝光固化樹脂的容器,投影光從下方將光圖案向上投射至容置框體的透明底部而使容置框體內液態的光固化材料得以固化。然而,由於凡得瓦偶極力、化學黏結力與吸引力的結果,使光固化層與容置框體之間產生沾黏的現象,從而造成搭建平台對光固化層有難以拉拔的問題。離型力的大小係與上述力量及光固化層之面積成正相關,且為高精度列印的最重要限制因素之一。離型力過大的話,易導致以固化的立體物件於離型過程中的硬性脫離而造成破損,導致脫模效果不佳,甚至造成樹脂槽因過度形變而報廢。The resin tank is a container for containing the light-curing resin, and the projection light projects the light pattern upward to the transparent bottom of the housing frame from below to solidify the liquid light-curing material in the housing frame. However, due to the Van der Waals dipole force, chemical bonding force and attractive force, adhesion occurs between the photocurable layer and the accommodating frame, which causes the problem of difficulty in drawing the photocurable layer by the building platform. The release force is positively related to the above-mentioned force and the area of the photocurable layer, and is one of the most important limiting factors for high-precision printing. If the release force is too large, it is easy to cause the solidified three-dimensional object to be hardly separated during the release process and cause damage, resulting in poor demolding effect, and even causing the resin tank to be scrapped due to excessive deformation.
為了解決上述問題,有些改善沾黏現象的技術係於容置框體的底部塗布防沾黏的薄膜材料,例如鐵弗龍(Teflon)或矽膠(silicone),藉此來防止光固化層沾黏在容置框體,但此作法需考量塗布的平整性及均勻度,以及當防沾黏膜的厚度增加時,可能會降低槽底的透光度,影響立體列印的品質;再者,當防沾黏膜失去作用時,整個樹脂槽形同報廢,需要重新購置或視製作新的樹脂槽。In order to solve the above problems, some techniques to improve the adhesion phenomenon are to coat the bottom of the housing frame with an anti-adhesion film material, such as Teflon or silicone, to prevent adhesion of the photocurable layer In the housing frame, this method needs to consider the flatness and uniformity of the coating, and when the thickness of the anti-sticking film increases, the transmittance of the bottom of the groove may be reduced, which affects the quality of the three-dimensional printing; When the anti-sticking film loses its effect, the entire resin tank is scrapped, and a new resin tank needs to be purchased or made.
另外則有技術是將鐵弗龍(Teflon)材質的薄膜以螺絲鎖固或夾具等物理性方式固定在樹脂槽的底部,能夠有助於降低立體物件與槽底的離形力,並可方便替換薄膜,像是中國發明專利公告CN 105365218 B號所揭露的DLP光固化3D打印機用樹脂槽、以及中國發明專利公開CN 107336438A號所揭露的一種可快速換膜DLP光固化3D打印機用樹脂槽及其裝配方法;然而,上述之專利技術在固定薄膜時,皆需要使用繁雜瑣碎的固定元件,不但組裝費時,同時也會增加列印裝置的整體體積。In addition, there is a technology to fix the Teflon film to the bottom of the resin tank by screws or clamps, which can help reduce the separation force between the three-dimensional object and the bottom of the tank, and is convenient Replacement films, such as the resin tank for DLP light-curing 3D printers disclosed in China Invention Patent Publication CN 105365218 B, and the resin tank for DLP light-curing 3D printers disclosed in China Patent Publication CN 107336438A that can quickly change the film and The assembly method; however, the above-mentioned patented technology requires the use of complicated and trivial fixing elements when fixing the film, which not only takes time for assembly, but also increases the overall volume of the printing device.
是以,如何改善上述問題並且提升組裝樹脂槽及從樹脂槽分離固化物的便利性,申請人有鑑於習知技術中所產生之缺失,經過悉心試驗與研究,並一本鍥而不捨之精神,終構思出本發明以解決習知技藝的缺點。Therefore, how to improve the above problems and improve the convenience of assembling the resin tank and separating the cured product from the resin tank, the applicant, in view of the deficiencies in the prior art, after careful experimentation and research, and the spirit of perseverance, finally The present invention was conceived to solve the shortcomings of the prior art.

以下,舉例說明前述3D列印裝置用容器的製作方法之實施例。Hereinafter, an example of the manufacturing method of the container for the aforementioned 3D printing device will be illustrated.
《實施例1至5》"Examples 1 to 5"
在實施例1至5中,採用圖2至圖4所示之3D列印裝置用容器的製作方法分別製得3D列印裝置用容器S1至3D列印裝置用容器S5,所採用的機能性透光膜為氟化乙烯丙烯共聚物(FEP)薄膜,實施例1至5的差異在於在步驟(c)將基底膜與容器的底部基板貼合的過程中,基底膜承重的重量依序為600g、1200g、1800g、2400g、3000g。接著,分別使用3D列印裝置用容器S1至3D列印裝置用容器S5進行分離力測試。In Examples 1 to 5, the 3D printing device container S1 to 3D printing device container S5 were produced using the 3D printing device container manufacturing method shown in FIGS. 2 to 4, and the functionalities used The light-transmitting film is a fluorinated ethylene propylene copolymer (FEP) film. The difference of Examples 1 to 5 is that in the process of bonding the base film to the bottom substrate of the container in step (c), the weight of the base film is sequentially 600g, 1200g, 1800g, 2400g, 3000g. Next, the 3D printing device container S1 to the 3D printing device container S5 were used to perform a separation force test.
分離力測試方法說明如下:The separation force test method is explained as follows:
請參閱圖7,其為顯示分離力測試中的裝置示意圖。將台科三維公司所提供的可見光樹脂材料NT-02盛裝於3D列印裝置用容器P中,選用50mm*50mm的方塊圖檔進行曝光,Z軸上升速度為2.5mm/S,曝光光源為下照式投影機,投影時間為60秒,以確保曝光區域產生完全固化並成功附著至裝設有S型荷重元的成型平台上。當曝光完成後,荷重元向上移動並產生分離力。藉此,將3D列印裝置用容器S1至3D列印裝置用容器S5經由上述分離力測試方法所產生之分離力由荷重元產生訊號並由紀錄器所記錄下來,所得數值紀錄於表1。Please refer to Figure 7, which is a schematic diagram showing the device in the separation force test. Put the visible light resin material NT-02 provided by Taike 3D company in container P for 3D printing device, choose 50mm*50mm block diagram file for exposure, Z axis rising speed is 2.5mm/S, exposure light source is down The projection time of the illuminated projector is 60 seconds to ensure that the exposed area is completely cured and successfully attached to the molding platform equipped with the S-shaped load cell. When the exposure is completed, the load cell moves upward and generates a separation force. Thereby, the separation force generated by the 3D printing device container S1 to the 3D printing device container S5 through the above-mentioned separation force testing method is generated by the load cell and recorded by the recorder. The obtained values are recorded in Table 1.
《比較例1》"Comparative Example 1"
在比較例1中選用市售光固化3D列印機台的3D列印裝置用容器N1,該3D列印裝置用容器N1是由習知的螺絲鎖固方式,將容器底板與機能性透光膜以夾具和螺絲鎖固製作而得,所使用的機能性透光膜與實施例1至5相同,為氟化乙烯丙烯共聚物(FEP)薄膜。In Comparative Example 1, the 3D printing device container N1 of a commercially available light-curing 3D printing machine is selected. The 3D printing device container N1 is fixed by a conventional screw locking method, and the container bottom plate and the function are transparent. The film is made by fixing with clamps and screws. The functional light-transmitting film used is the same as in Examples 1 to 5, which is a fluorinated ethylene propylene copolymer (FEP) film.
接著,使用3D列印裝置用容器N1進行分離力測試,並將所得數值紀錄於表1。Next, use the container N1 for the 3D printing device to perform a separation force test, and record the obtained values in Table 1.
表1
由上述表1可知,3D列印裝置用容器S1至S5的分離力依序為1.6N、2.05N、2.28N、2.53N、3.12N,而樹脂槽N1的分離力為14.63N,顯示3D列印裝置用容器S1至S5的分離力明顯小於3D列印裝置用容器N1。由此可知,當使用本發明之3D列印裝置用容器盛裝樹脂材料進行光固化反應時,能夠有效降低硬化後的樹脂材料與3D列印裝置用容器底部的分離力,進而避免在3D列印的過程當中拉拔而導致印列物件損壞。From Table 1 above, it can be seen that the separation force of the containers S1 to S5 for the 3D printing device is 1.6N, 2.05N, 2.28N, 2.53N, 3.12N, and the separation force of the resin tank N1 is 14.63N, showing 3D rows The separation force of the containers S1 to S5 for the printing device is significantly smaller than that of the container N1 for the 3D printing device. It can be seen from this that when the resin material used in the container for the 3D printing device of the present invention is used for the photocuring reaction, the separation force between the cured resin material and the bottom of the container for the 3D printing device can be effectively reduced, thereby avoiding 3D printing In the process of drawing, the printed object is damaged.
綜上所述,本發明用於光固化立體造型裝置之3D列印裝置用容器,使用具有抗沾黏性、柔性、化學兼容性,電氣可靠性,寬熱範圍、高透光率以及機械韌性的透光薄膜,並可進一步與作為為底面支撐材之定位膜貼附結合後,取代用以成型物件之3D列印裝置用容器的面光底面,能夠改善現有技術於離型過程不穩定的問題,亦進一步解決3D列印裝置用容器因過度形變或是底面抗沾黏薄膜失效而報廢的問題。In summary, the container used in the 3D printing device of the light-curing three-dimensional modeling device of the present invention has anti-sticking properties, flexibility, chemical compatibility, electrical reliability, wide thermal range, high light transmittance and mechanical toughness. The transparent film can be further combined with the positioning film as the bottom support material to replace the smooth bottom surface of the container for the 3D printing device used to mold the object, which can improve the instability of the prior art in the release process The problem also further solves the problem that the container for the 3D printing device is scrapped due to excessive deformation or failure of the bottom anti-sticking film.
