【摘要】：针对3D打印机喷头组件的打印精度低和表面粗糙、安装不便、喷头易堵塞等问题,建立喷头组件装配模型,分析其模型特征。并结合傅里叶热传导定律,利用ANSYS workbench对喷头组件进行热力学分析,经仿真分析和实践应用,对打印头组件和铁氟龙管的结构进行重新优化设计。最后将原始喷头组件和改进后的喷头组件进行比较,得到改善后的打印机喷头堵塞频次明显降低,流畅度更好,打印件表面质量也得到了提高,主要散热部件自身散热效率至少提高8.17%,为3D打印机的进一步推广和发展提供了参考。
[Abstract]:Aiming at the problems of low printing precision, rough surface, inconvenient installation and easy clogging of spray nozzle assembly of 3D printer, the assembly model of nozzle assembly is established and its model characteristics are analyzed. Combined with Fourier's heat conduction law, the thermodynamics analysis of nozzle assembly is carried out by using ANSYS workbench. The structure of printing head assembly and Teflon tube is redesigned by simulation analysis and practical application. Finally, comparing the original nozzle assembly with the improved nozzle assembly, the improved printer nozzle clogging frequency is obviously reduced, the fluency is better, and the surface quality of the printed part is also improved. The heat dissipation efficiency of the main cooling parts is at least 8.17, which provides a reference for the further promotion and development of 3D printers.
