Three-dimensional (3D) printing is a layer-by-layer deposition process that enables the fabrication of complex shapes. The sensing of the condition of the printed multilayer structure is complicated by the small thickness of each layer and the complex geometry of the 3D structure. This paper reports electrical-resistance-based self-sensing ability in a 3D printed polymer structure by the addition of carbon nanofiber to the UV-curable acrylate ester resin prior to printing by bottom-up stereolithography. The low content of nanofiber (0.065 vol.%) renders conductivity to the printed material while maintaining adequate UV transparency for curing the resin without reducing the modulus of the printed structure. The self-sensing ability is demonstrated for the sensing of both reversible and irreversible strain, which is compressive in the direction perpendicular to the layers, as indicated by measuring the electrical resistance (four-probe method) either in the direction in the plane of the layers or an oblique direction across the thickness. The in-plane resistivity and resistance in oblique direction both reversibly increases due to through-thickness reversible compressive strain and the corresponding in-plane reversible tensile strain. The fraction changes in in-plane resistance and in oblique direction per unit in-plane strain (gage factor) are considerable larger than the gage factor that is only caused by strain effect.
