Laser-induced graphene (LIG), a structure synthesized by one-step process through laser treatment of commercial polyimide (PI) film in an ambient atmosphere, has been shown to be versatile material applications ranging from energy storage water treatment. However, the as developed produces only 2D product on PI substrate. Here, 3D LIG foam printing is basis laminated object manufacturing, widely used additive-manufacturing technique. A subtractive laser-milling yield further refinements structures also and here. By combining both techniques, various objects are printed. The foams show good electrical conductivity mechanical strength, well viability flexible electronic sensor applications.
