Signal Transmission Behavior Of Conductive Filaments In The Context Of Fused Filament Fabrication (FFF) Procedure

The present paper investigates the signal transmission behavior of conductive filaments in the context of fused filament fabrication (FFF) procedure. By way of introduction, theoretical research is carried out. Subsequently, a concept including the construction of the test specimens for the acquisition of the measurement data is to be developed. The series of measurements to be performed in conjunction with the required measurement setups will also be defined. Within measurement series 1, three conductive filaments are compared with each other, which differ in their material composition but are identical in geometry. Measurement series 2 is used to investigate possible variations within the signal behavior of forward and return conductors of the test specimens due to differences in length and distance. Therefore, the findings obtained through designing and manufacturing the test specimens as well as the measurement results are explained and discussed.

This research is pivotal for advancing the 3D printed electronics industry, particularly in optimizing signal transmission in additively manufactured conductive structures. By analyzing the signal transmission characteristics of different conductive filaments, the study aims to enhance the performance and reliability of 3D printed electronic components. The insights gained from this investigation will contribute significantly to the development of more efficient additive manufacturing processes and the broader application of 3D printed electronics.
