三自由度微曲面电路3D打印方法及工艺
Method and process of micro surface circuit printing using a three degrees of freedom 3D printer
摘要
Abstract
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 con-formal 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 re-constructs 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 opti-mal 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 condi-tions,the printed circuit is continuous and uniform,showcasing its superior quality.关键词
