| 针对柔性器件制备工艺复杂、定制化程度低等问题，课题组设计了直写式硅胶3D打印系统。该系统利用精密螺杆泵将高黏度单组份室温固化硅橡胶挤出，通过三轴运动平台对胶线的轨迹进行精准控制，经逐层堆积以及室温固化实现柔性器件的精确制备；通过测量堆垛结构的线距和对标准哑铃试样力学性能测试，对制备的柔性器件进行尺寸及静力学分析。结果表明：制备样品尺寸的相对误差在3%以内，哑铃式样机械性能良好，系统可以按要求进行柔性器件打印。直写式硅胶3D打印系统为柔性器件的制备提供更简化的工艺以及丰富的个性化定制。 |

| Aiming at the problems of complex fabrication process and low degree of customization of flexible devices, a direct writing silicagel 3D printing system was designed.A precision screw pump was used to extricate high viscosity single component curing silicone rubber at room temperature. The trajectory of the rubber line was precisely controlled by a three axis moving platform, and the precise preparation of flexible devices was realized by layer by layer stacking and curing at room temperature. The size and statics of the flexible device were analyzed by measuring the line distance of the stack structure and testing the mechanical properties of the standard dumbbell pattern. The results show that the relative error of the sample size is less than 3%, and the dumbbell pattern has good mechanical properties, which proves that the system can print flexible devices as required. The direct writing silicone 3D printing system provides a simplified process and rich customization for the fabrication of flexible devices." |
