金属三维打印装置及其打印方法技术领域 Metal three-dimensional printing device and printing method thereof

[0001] 本发明涉及金属三维打印领域，尤其涉及一种光固化金属三维打印装置、一种熔融沉积成型的金属三维打印装置和各自的打印方法。本发明是基于申请日为 2 016年 12月 5日、申请号为 CN201611103638.3的中国发明专利申请，上述发明的内容引入本文作为参考。 [0001] The present invention relates to the field of metal three-dimensional printing, and more particularly to a photocurable metal three-dimensional printing apparatus, a fused deposition metal three-dimensional printing apparatus, and a respective printing method. The present invention is based on a Chinese invention patent application filed on Dec. 5, 196, the entire disclosure of which is incorporated herein by reference.

背景技术 Background technique

[0002] 3D打印机又称三维打印装置，是一种利用快速成型技术的机器，以数字模型文件为基础，采用成型材料，通过逐层打印的方式来构造三维的实体。在打印前，需要利用计算机建模软件建模，再将建成的三维模型 "分区 "成逐层的截面，即切片，从而指导 3D打印装置逐层打印。 3D打印装置在产品制造业获得了广泛的应用。具体按照成型方式 FDM、 DLP、 SLA、 SLS、 SLM、 3DP等 3D成型的方法 [0002] A 3D printer, also known as a three-dimensional printing device, is a machine that utilizes rapid prototyping technology to construct a three-dimensional entity by layer-by-layer printing based on a digital model file. Before printing, it needs to be modeled by computer modeling software, and then the partitioned 3D model is “partitioned” into a layer-by-layer section, ie, slice, to guide the 3D printing device to print layer by layer. 3D printing devices have found wide application in the product manufacturing industry. Specifically according to the molding method FDM, DLP, SLA, SLS, SLM, 3DP, etc. 3D molding method

[0003] 熔融沉积成型 (FDM)是通过在水平移动的打印头挤出加热熔融后的成型材料，并在成型座逐层叠堆形成三维模型。另外一种打印方式是激光烧结 (SLM)，其利用粉末激光烧结成型，基本原理是用粉末铺设一层后用激光烧结，然后再用粉末铺设一层，再激光烧结一次，循环打印出三维立体实物。 [0003] Fused Deposition Modeling (FDM) is a method of forming a three-dimensional model by extruding a heated molten molding material on a horizontally moving print head and stacking the piles in a molding stand. Another printing method is laser sintering (SLM), which uses powder laser sintering. The basic principle is to use a powder to lay a layer and then use a laser to sinter, then use a powder to lay a layer, then laser-sinter once, and cycle out the three-dimensional Real.

[0004] 然而上述两种打印方法都存在一定的局限性，如需要大功率的激光头或者高温熔化，才能够实现金属打印，这就需要三维打印设备非常专业的保护，而且能源消耗较多，成本非常高。 [0004] However, the above two printing methods have certain limitations, such as requiring a high-power laser head or high-temperature melting to enable metal printing, which requires a very professional protection of the three-dimensional printing device, and energy consumption is high. The cost is very high.

[0005] 而 DLP三维打印是利用数字光处理技术使用一个投影仪逐层固化液态光敏树脂[0005] DLP three-dimensional printing is a layer-by-layer curing of liquid photosensitive resin using a projector using digital light processing technology.

，其能够打印出来具有非常精细分辨率的物体。 It is capable of printing objects with very fine resolution.

[0006] 现有的 DLP光固化 3D打印装置包括光发射装置、打印平台与树脂槽，打印平台位于树脂槽内，光发射装置朝向打印平台照射，继而在打印平台上逐层形成需要打印的物体。 [0006] The existing DLP photocuring 3D printing device includes a light emitting device, a printing platform and a resin tank, the printing platform is located in the resin tank, the light emitting device is irradiated toward the printing platform, and then the object to be printed is formed layer by layer on the printing platform. .

[0007] 然而，由于打印平台在树脂槽内上下移动，一方面，由于液体光敏树脂与打印平台的接触，导致打印平台向上的作用力很大，容易导致打印装置液态树脂槽底部材料损坏。另一方面，由于平台的移动将会存在误差，导致打印物***置以及打印精度存在一定的误差。同吋由于一般成像光用于对树脂等液态光固化材料进行照射固化，其能量较小，故无法对金属材料打印成型，使用方面存在局限性。且光固化的成像方式由于成型材料缺乏回收结构，通常会造成成型材料的大量浪费。 [0007] However, since the printing platform moves up and down in the resin tank, on the one hand, due to liquid photosensitive resin and printing The contact of the platform causes the printing platform to have a large upward force, which easily causes damage to the material of the bottom of the liquid resin tank of the printing device. On the other hand, there will be errors due to the movement of the platform, resulting in a certain error in the position of the printed object and the printing accuracy. Since the general imaging light is used for irradiating and curing a liquid photocurable material such as a resin, the energy thereof is small, so that the metal material cannot be printed and formed, and there are limitations in use. And the photocuring imaging method usually causes a large amount of waste of the molding material due to the lack of a recycling structure of the molding material.

有益效果 Beneficial effect

[0039] 本方案通过在第一平台上承载成型材料，第二平台用于成像，继而利用刮板逐层地向第二平台输送成型材料，并在光发射装置对成型材料中的液态光固化材料固化，由于成型材料包括液态光固化材料和金属粉末，故金属粉末通过液态光固化材料作为粘结剂进行位置三维固化，继而可实现金属三维的初步成型，同吋在逐层光固化成型吋经过切削装置进行刨平、切削或形状的打磨，后续可通过高温固化烧结将光固化材料去除并实现金属粉末之间的融合连接，最终完成金属模型的三维打印，由于利用的是 DLP光固化进行初步成型，其打印成型效率高和精度高，且相比于昂贵的 SLM金属三维打印装置， SLM金属三维打印装置不仅价格高、后期维护成本大、消耗成本高，本案的光固化金属三维打印装置对金属模型的打印不仅打印成本较低且结构较为简单，易于维护。同吋金属粉末占 60%，成型材料呈粘稠状材料，使得成型材料更为具有附着力，也提高金属打印的成像品质。以及通过清洁装置对切削后的多余的成型材料进行清洁和回收。 [0039] The solution passes the molding material on the first platform, the second platform is used for imaging, and then the molding material is conveyed layer by layer to the second platform by the squeegee, and the liquid light is solidified in the molding material by the light emitting device. The material is solidified. Since the molding material includes the liquid photocurable material and the metal powder, the metal powder is three-dimensionally solidified by the liquid photocurable material as a binder, and then the three-dimensional preliminary molding of the metal can be realized, and the layer is formed by layer-by-layer photocuring. After the cutting device is used for planing, cutting or shape grinding, the photocurable material can be removed by high-temperature curing and sintering, and the fusion connection between the metal powders can be realized, and the three-dimensional printing of the metal model is finally completed, which is performed by using DLP light curing. Initial molding, high printing efficiency and high precision, and compared to the expensive SLM metal three-dimensional printing device, SLM metal three-dimensional printing device is not only high in price, high in maintenance cost, high in cost, and the light-cured metal three-dimensional printing device of the present invention Printing on metal models is not only cheaper to print The structure is simple and easy to maintain. The same metal powder accounts for 60%, and the molding material is a viscous material, which makes the molding material more adhesive and improves the image quality of metal printing. The excess molding material after cutting is cleaned and recycled by a cleaning device.

[0040] 并且，通过在第一平台上承载金属粉末，第二平台用于成像，继而利用刮板逐层地向第二平台输送金属粉末，同吋利用喷嘴均匀地朝向金属粉末喷涂液态光固化材料，并在光发射装置对成型材料中的液态光固化材料固化，由于成型材料包括液态光固化材料和金属粉末，故金属粉末通过液态光固化材料作为粘结剂进行位置三维固化，继而可实现金属三维的初步成型，同吋在逐层光固化成型吋经过切削装置进行刨平、切削或形状的打磨，后续可通过高温固化烧结将光固化材料去除并实现金属粉末之间的融合连接，最终完成金属模型的三维打印，由于利用的是 DLP光固化进行初步成型，其打印成型效率高和精度高，且相比于昂贵的 SLM金属三维打印装置， SLM金属三维打印装置不仅价格高、后期维护成本大、消耗成本高，本案的光固化金属三维打印装置对金属模型的打印不仅打印成本较低且结构较为简单，易于维护。以及通过清洁装置对切削后的多余的成型材料进行清洁和回收。 [0040] Moreover, by carrying metal powder on the first platform, the second platform is used for imaging, and then the metal powder is transported to the second platform layer by layer by means of the scraper, and the liquid light is solidified by spraying the nozzle uniformly toward the metal powder. The material, and the liquid photocuring material in the molding material is solidified in the light emitting device. Since the molding material includes the liquid photocuring material and the metal powder, the metal powder is solidified by the liquid photocuring material as a binder, and then can be realized. The initial three-dimensional forming of the metal, the same layer is carried out in a layer-by-layer photocuring process, and the cutting device is used for planing, cutting or shape grinding, which can be subsequently cured by high temperature curing. The photocurable material removes and realizes the fusion connection between the metal powders, and finally completes the three-dimensional printing of the metal model, and the initial molding is performed by using DLP light curing, which has high printing efficiency and high precision, and is compared with the expensive SLM metal. The three-dimensional printing device and the SLM metal three-dimensional printing device not only have high price, high maintenance cost and high cost, and the light-cured metal three-dimensional printing device of the present invention not only has low printing cost and simple structure, but also is easy to maintain. And cleaning and recycling the excess molding material after cutting by the cleaning device.

[0041] 另外，通过耗材供给组件和打印头组件分别打印具有不同金属材料的成型材料，同吋采用打印头挤出成像的原理，利用 FDM的成型方式进行三维打印，同吋在逐层光固化成型吋经过切削装置进行刨平、切削或形状的打磨，其成型效率高、精度高、成本低，继而能够实现多金属材料的三维模型打印，其能够形成具有新金属性能的三维模型。以及通过清洁装置对切削后的多余的成型材料进行清洁和回收。 [0041] In addition, the molding material having different metal materials is separately printed by the consumable supply component and the print head assembly, and the principle of extrusion imaging of the print head is adopted, and the three-dimensional printing is performed by the FDM molding method, and the layer-by-layer photocuring is performed simultaneously. The forming crucible is leveled, cut or shaped by a cutting device, which has high molding efficiency, high precision and low cost, and can then realize three-dimensional model printing of multi-metal materials, which can form a three-dimensional model with new metal properties. The excess molding material after cutting is cleaned and recycled by a cleaning device.

[0042] 再者，通过上述不同方式进行金属三维成像，同吋在逐层光固化成型吋经过切削装置进行刨平、切削或形状的打磨，其成型效率高、精度高、成本低，上述方案中的光固化金属三维打印方法对金属模型的打印不仅打印成本较低且结构较为简单，易于维护。 [0042] Furthermore, the three-dimensional imaging of the metal is performed by the above-mentioned different methods, and the layer-by-layer photo-curing molding is subjected to planing, cutting or shape grinding by the cutting device, and the molding efficiency is high, the precision is high, and the cost is low. The three-dimensional printing method of the photocured metal in the printing of the metal model is not only low in printing cost, but also simple in structure and easy to maintain.

[0151] 对上述第一实施例至第六实施例得到的三维成型丝料进行样本采样，对这些样本按照标准 GB/T9341-2008进行测试。样本的形状为：长 80.00毫米（mm)，宽 10 .00毫米（mm),厚 4.11毫米（mm)。样本测试的速度采用线速度： 10.0毫米 /分钟 (mm/min)。样本测试的跨度为 66毫米（mm) 。样本的测试结果如图 10所示。 The samples of the three-dimensional forming wires obtained in the above first to sixth embodiments were sampled, and the samples were tested in accordance with the standard GB/T9341-2008. The shape of the sample is: 80.00 mm (mm) long, 10.00 mm (mm) wide, and 4.11 mm (mm) thick. The speed of the sample test was linear speed: 10.0 mm / min (mm / min). The sample test spans 66 mm (mm). The test results of the sample are shown in Figure 10.

[0152] 从图 10可见，在上述实验条件下，三维成型丝料的弯曲强度大于 6.9MPa，从而实现了金属基三维成型丝料的弯曲变形且不会折断。 As can be seen from FIG. 10, under the above experimental conditions, the bending strength of the three-dimensional shaped wire is greater than 6.9 MPa, thereby realizing the bending deformation of the metal-based three-dimensional forming wire without breaking.

[0153] 另外，对第十一实施例等到的三维成型丝料进行样本采样，对这些样本按照标准 ASTM D790-07进行测试。样本的形状为：长 127.00毫米（mm)，宽 12.70毫米 (mm),厚 3.20毫米（mm)。样本测试的速度采用线速度： 10.0毫米 /分钟（mm/mi n)。样本的测试结果如图 11所示。 Further, sample sampling was performed on the three-dimensionally shaped yarns of the eleventh embodiment, and the samples were tested in accordance with the standard ASTM D790-07. The shape of the sample is: 127.00 mm (mm) long, 12.70 mm (mm) wide, and 3.20 mm (mm) thick. The speed of the sample test was linear speed: 10.0 mm / min (mm / mi n). The test results of the sample are shown in Figure 11.

[0154] 从图 11可见，在上述实验条件下，三维成型丝料的弯曲强度大于 36MPa，从而实现了金属基三维成型丝料的弯曲变形且不会折断。 [0154] As can be seen from FIG. 11, under the above experimental conditions, the bending strength of the three-dimensional shaped wire is greater than 36 MPa, thereby achieving bending deformation of the metal-based three-dimensional forming wire without breaking.

[0155] 在其它的实施方式中，本发明的三维成型丝料不包含热稳定剂，并且依然能够完成本发明的发明目的，也就是在不包含热稳定剂的情况下，三维成型丝料的弯曲强度能够达到要求，盘绕在丝料盘上。 [0155] In other embodiments, the three-dimensional shaped silk of the present invention does not contain a heat stabilizer, and is still capable of accomplishing the object of the present invention, that is, in the case of containing no heat stabilizer, three-dimensionally shaped silk material The bending strength can be achieved and coiled onto the wire tray.

[0156] 在其它的实施方式中，三维成型丝料的组份还包括磁性材料如四氧化三铁，在上述三维成型丝料的制造方法中，在准备步骤和挤出步骤中，磁性材料粉末与其它原料如粘结剂等一起加入混合。三维成型丝料的组份还可以包括着色剂或者染料，以使得丝料具有不同的颜色。柔韧性增强剂例如是增塑剂，增塑剂例如为邻苯二甲酸酯类（或邻苯二甲酸盐类亦称酞酸酯）的化合物，邻苯二甲酸酯类塑化剂包括：邻苯二甲酸二（2-乙基己）酯（DEHP) 、邻苯二甲酸二正辛酯（DNOP或 DnOP) 、邻苯二甲酸丁苄酯（BBP) 、邻苯二甲酸二仲辛酯（DC P) 、邻苯二甲酸二环己酯（DCHP) 等。本发明进一步对三维成型丝料的组份中的物料所起的作用或机理进行了阐述，但是这种作用机理不对本发明的保护范围起到限制作用。由于金属材料与粘结剂之间的密度相差较远，因此很难形成均匀的混合效果，而在组份中增加分散剂之后就可以对原料的均匀混合起到很好的作用。本发明的金属材料粉末和粘结剂形成丝料后，由于这种丝料的脆性较大，在弯曲的吋候容易发生折断，而在组份中增加了柔韧性增强剂如增塑剂之后，其柔韧性或者弯曲强度得到了提升，上述表征结果可以说明。对于本发明的三维成型丝料，当其粘结剂、增塑剂、分散剂采用聚合物材料吋，由于聚合物分子的分子量是一个较宽的范围，这就会造成三维成型丝料的熔融温度出现较大范围的波动，例如熔融温度范围在 200°C至 230°C内，而增加了热稳定剂后，可以使得三维成型丝料的熔融温度限定在一个较小的范围内，例如 200°C至 2 05°C之间。 [0156] In other embodiments, the component of the three-dimensional shaped filament further includes a magnetic material such as triiron tetroxide, in the method for producing the three-dimensional shaped silk material, in the preparation step and the extrusion step, the magnetic material powder It is added and mixed together with other raw materials such as a binder. The components of the three-dimensional shaped filament may also include a colorant or dye such that the filaments have different colors. The flexibility enhancer is, for example, a plasticizer, and the plasticizer is, for example, a compound of a phthalate (or a phthalate), and the phthalate plasticizer includes: Di(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate Ester (DNOP or DnOP), butyl benzyl phthalate (BBP), di-octyl phthalate (DC P), dicyclohexyl phthalate (DCHP), etc. The present invention further describes the action or mechanism of the materials in the components of the three-dimensional shaped wire, but this mechanism of action does not limit the scope of protection of the present invention. Since the density between the metal material and the binder is far apart, it is difficult to form a uniform mixing effect, and the addition of the dispersing agent in the component can play a good role in the uniform mixing of the raw materials. After the metal material powder and the binder of the present invention form a silk material, since the silk material has a large brittleness, it is likely to be broken at the time of bending, and a flexibility enhancer such as a plasticizer is added to the composition. The flexibility or bending strength is improved, and the above characterization results can be explained. For the three-dimensional forming wire of the present invention, when the binder, the plasticizer and the dispersing agent are made of a polymer material, since the molecular weight of the polymer molecule is a wide range, the melting of the three-dimensional forming wire is caused. The temperature has a wide range of fluctuations, for example, the melting temperature ranges from 200 ° C to 230 ° C. After the heat stabilizer is added, the melting temperature of the three-dimensional forming wire can be limited to a small range, for example, 200. °C to 2 05 °C.

[0157] 最后需要说明的是，本发明不限于上述的实施方式，诸如弯曲强度大于 6.9MPa [0157] Finally, it should be noted that the present invention is not limited to the above embodiments, such as a bending strength greater than 6.9 MPa.

，弯曲强度大于 6.5MPa的设计等也在本发明的权利要求保护范围之内。 A design having a bending strength of more than 6.5 MPa is also within the scope of the claims of the present invention.

This filamentary material enables the bending of the wire-like material, and the bending moment does not break, and its application in the FDM three-dimensional printer achieves a breakthrough. By using the silk material of the invention for printing three-dimensional objects, an object of metal material can be manufactured, and compared with the molding process of the metal three-dimensional object of the traditional process, after the filament material provided by the invention is applied, the FDM three-dimensional printer is used for molding and molding.
