摘要
针对碳纤维长纤3D打印复杂模型的路径跳转问题,以三维模型切片处理后的G代码文件为基础,对其进行3D打印跳转点识别;基于三维路径坐标与远端切断装置间的距离关系,实现打印跳转点与纤维切断点的精确匹配,进行连续性纤维远端切断处理。通过不同打印路径的三维模型跳转点与断点的仿真分析,以及碳纤维长纤3D打印系统对单层及多层模型的3D打印测试,验证了路径跳转处理方法对连续纤维复杂模型3D打印成型的可行性。算法为碳纤维长纤3D打印的实现提供基础。
For the path jumping problem of long carbon fiber composite materials 3D Printing, the jumping point identification method of 3D printing based on the G-code file is researched. Based on the distance relations between path coordinates and distal cutting-off device, the accurate distance matching between the printing jump point and fibre cutting point is realized in order to execute the continuous fibre distally cuts off in the 3D printing process. ,. The relationship of printing jump point and fibre cutting point of different printing paths is identified by simulation analysis. Then, single-layer and muhi-layer model 3D printing experiments are implemented using long carbon fiber materials. The experiment result shows that complex models 3D Printing of long carbon fiber composite materials is feasible with paths jump processing method. It provides the basis for the realization of long carbon fiber composite materials 3D Printing.
