Abstract

A 3D printing manufacturing method of a three-dimensional structure electronic device. First, according to the performance requirements of the workpiece to be formed, the spatial distribution of the circuit in the three-dimensional structure electronic device and the geometric size of the matrix structure are designed, a three-dimensional CAD model is established, and the model is processed according to the processing direction. Layered processing, to obtain the material distribution of each layer section, write the relative motion program of the print head integrated device and the working platform, and then select the wire printing material and matrix structure printing material that meet the performance requirements, and then print the substrate, on the working platform Form the matrix structure, then switch the print head, print the wire, the movement mechanism drives the working platform to drop a layer thickness, repeat the printing process of printing the base material and printing wire, until the entire matrix structure and wire are printed, and the structural electronics are obtained. The invention realizes The synchronous printing of wires and base insulating medium can realize arbitrary arrangement in three-dimensional space.

Description

technical field [0001] The invention relates to the technical field of structural electronics manufacturing, in particular to a 3D printing manufacturing method of a three-dimensional structural electronic device. Background technique [0002] Structural electronics refers to a three-dimensional electrical structure in which circuits and electronic components are attached or embedded on a substrate structure according to a certain three-dimensional space layout. Its core features are: the electrical part has a three-dimensional spatial layout, which improves the space utilization rate and reduces the volume; the matrix structure has a three-dimensional shape, so that the structural electronics as a whole have certain mechanical properties. Taking advantage of these beneficial properties, structural electronics can be used to manufacture a large number of new electronic devices to realize the integration of function and structure, such as curved surface conformal electronic d...
