Fig. 2From: Fused deposition modelling (FDM) of composites of graphene nanoplatelets and polymers for high thermal conductivity: a mini-reviewSchematic diagram illustrating the effect of voids and printing direction on TC. a, b filaments printed with the same orientation generate voids perpendicularly arranged (x-z directions), with respect to the thermal conduction direction (y-direction) thus maximizing TC along the conductive axis (y-axis) and c, d, filaments printed in different orientations generate voids along the thermal conduction direction, thus reducing TC along the conductive axis (y-axis)Back to article page
