Graphene-Polylactic Acid (Gr-PLA) composites are fabricated by Fused Deposition Modeling (FDM), employing a novel composite filament. Printed layer morphology of Gr-PLA is compared with pure PLA to assess the influence of graphene on polymer curing during printing. Effect of printing speed and temperature on the material morphology is also studied to evaluate the influence of processing parameters on the morphology of material being printed. Tensile tests and post tensile microscopic examination is carried out to determine the mechanical strengths and deformation mechanisms. Since PLA is a material suitable for orthopedic applications, osseo-integrable cellular scaffolds of pure PLA and Gr-PLA are also printed and their response to compressive loading is probed. Deformation mechanisms are studied by electron microscopy.
