    摘要:

    3D 打印技术在航天、军工、机器人等领域应用广泛,但也存在诸多问题,如阶梯效应所带来的叠层误差、2.5D 制造原理导致的打印零件各向异性、支撑结构的打印及后处理导致的耗时和耗能等问题。针对上述不足,该文提出一种回转式曲面分层 3D 打印方法,对多自由度回转式 3D 打印设备的设计方法进行研究,通过构型综合和尺度综合确定了打印机构型及结构参数,提出了曲面打印路径规划方法。通过联合仿真与样机实验,验证了 3D 打印设备构型综合与尺度设计的有效性,为打印装备创新设计、曲面打印过程规划策略及相关实验研究提供了新思路。

    Abstract:

    3D printing technology has been widely applied in aerospace, military, robotics and many other fields. However, some problems need to be solved, such as stacking error caused by the stair-stepping effect, anisotropy of printing parts caused by the 2.5D manufacturing principle, and time-consuming and energy consumption caused by printing and post-processing supporting structure. This paper studies the 3D printing method of rotary surface, carries out the innovative design research of multi-degree of freedom rotary 3D printing equipment, determines the printer’s structural parameters based on dimension design, and puts forward the path planning methods for curved layer printing. This paper verifies the correctness of type synthesis and dimension design of the 3D printing equipment through co-simulation and prototype experiments. Meanwhile, preliminary experimental research results show the feasibility of applying 3D printing equipment to curved layer printing from a qualitative point of view. Results of this study provide new ideas for innovative design methods of printing equipment, planning strategies for curved layer printing and related experimental research.
