Abstract

This paper shows the design of an injector, using carbon nanotubes as inkjet material, implemented in a 3D printer. According to the available literature, few injectors are capable of depositing material. Due to the lack of information, the central part of this research is to develop a suitable device for ink injection that is capable of applying the Fused Deposition Modeling (FDM) method to print nanomaterial ink. The injector was designed using a CAD program based on an open-source desktop 3D printer, which allows it to be modified according to the needs of the injector. This prototype was manufactured in aluminum alloy 7075T6. Computational fluid dynamics (CFD) were carried out to analyze the behavior of the fluid when it passes through the injector, obtaining parameters such as pressure, velocity, and vorticity. An experimental matrix of the injector operation was carried out to achieve an adequate printing speed. The results show that the optimum speed was 250 ms, considering that a temperature of 100 °C is needed in the heated bed to dry the ink so that it does not undergo expansion.

摘要

本文展示了一种以碳纳米管作为喷墨材料的注射器的设计，该注射器应用于3D打印机中。根据现有文献，能够沉积材料的注射器很少。由于信息匮乏，本研究的核心部分是开发一种合适的喷墨装置，该装置能够应用熔融沉积建模（FDM）方法来打印纳米材料墨水。该注射器是基于一台开源桌面3D打印机，使用CAD程序设计的，这使得它能够根据注射器的需求进行修改。该原型由7075T6铝合金制造。进行了计算流体动力学（CFD）分析，以研究流体通过注射器时的行为，获得了压力、速度和涡度等参数。为了实现合适的打印速度，对注射器的操作进行了实验矩阵研究。结果表明，最佳速度为250毫秒，因为需要在加热床中达到100°C的温度来干燥墨水，使其不会膨胀。
