Herein, we presents a study on the fabrication and characterization of supercapacitor electrode by 3D printing. A colloidal suspension containing carbon nanotubes (CNTs) and cobalt ferrite nanoparticles (CoFe2O4 NPs) was used as ink. The ink was successfully printed on aluminium substrate using a modified 3D printer followed by solvent evaporation to form a porous CNTs/CoFe2O4 aerogel film. The characterization results showed that the film has porous surface, high electrical conductivity and
