Analysis of Current Carrying Capability of Graphene-Enhanced Conductive Polylactic Acid Based Filaments for 3D-Printing

The paper presents some investigations on the current carrying capabilities of 3D-printed graphene-enhanced conductive poly-lactic acid based samples. Such samples with different dimensions and shapes are tested at different currents and electrical and thermal measurements are performed. An automated measurement system is used for observing any change in sample resistance for the time span of each test. Simple qualitative conclusions modelling and simulation of resistance of 3D-printed samples will be performed and an empirical model for their maximal current capabilities will be identified.
