Abstract: 3D printing technology has emerged as a unique platform for rapid prototyping of various applications at low cost. Herein, we present 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 nickel foam and graphite paper substrates using a modified 3D printer followed by solvent evaporation to form a porous CNTs/CoFe2O4 aerogel film. The characterization results show that the film has porous surface, high electrical conductivity and good electrochemical properties, indicating its promising application as supercapacitor electrode for energy conversion and storage.
