Conductance based First Layer Monitoring for Fused Filament Fabrication

In this work we demonstrate the feasibility of conductance measurements as a diagnostic tool for successful 3D printing of first layers making use of conductive FFF materials. The influence of extrusion factor and nozzle-to-bed height were studied for their effect on traxel (printline) resistance and interlayer adhesion. A model based on earlier work was adapted to offer a base for evaluation of the quality of printed traxels.
