摘要
针对打印微曲面电路技术复杂、成本较高等问题,提出了一种使用三自由度打印机打印微曲面电路的方法,该方法旨在使用三自由度打印机在微曲面上打印共形电路,同时开发了一种自适应微曲面3D打印控制算法。该算法将DXF格式的文件作为输入,提取文件中的线路数据并对其进行离散处理,对离散后的数据逐点测量并根据反馈的数据进行线路重构,最终输出可以直接用于3D打印微曲面电路的G代码。利用三自由度打印机在不同基材制备的微曲面上完成电路打印实验和亮灯实验,验证了该方法的可行性。对3D打印微曲面电路的工艺参数进行研究,通过设计正交试验分析了工艺参数对打印的微曲面电路的影响,得到了最优工艺参数组合。结果表明,在针头直径为0.16 mm的情况下,打印气压为0.3 MPa、打印速度为100 mm/min和打印头高度为0.4 mm时,打印的微曲面电路连续且均匀,质量最优。
In response to the challenges posed by complex technology and high cost in micro-surface printing circuit,a method for printing micro-curved circuit is proposed using three Degrees of Freedom(3DoF)printer.This method focuses on achieving conformal circuit on micro-surface with the utilization of a 3DoF printer.Additionally,a self-adaption 3D printing control algorithm is also developed.The algorithm takes DXF format files as input,from which it extracts the line data.Subsequently,the data undergoes discrete processing,and each data point is systematically measured.Based on the feedback data,the algorithm then reconstructs the circuit.The final output of the algorithm is in the form of G-code,directly suitable for 3DoF printer.Finally,circuit printing experiments on micro-curved surface prepared from different substrates and lighting experiments are conducted to confirm the feasibility of this approach.Furthermore,the process parameters are also investigated for 3DoF printing micro-curved circuit.By employing a design orthogonal test,the impact of various printing parameters is analyzed,leading to the identification of the optimal parameter combination.The results demonstrated that the best circuit quality is achieved when using a needle diameter of 0.16 mm,a printing air pressure of 0.3 MPa,a printing speed of 100 mm/min,and a printing height of 0.4 mm.Under these conditions,the printed circuit is continuous and uniform,showcasing its superior quality.
