The invention relates to a stereoscopic printing device comprising a machine body, a rotating module, a maintaining tank, a lifting module, a forming platform, a curing module and a control module. The rotating module and the lifting module are arranged on the machine body; the maintaining tank is arranged on the rotating module; the forming platform is arranged on the lifting module; and the curing module is arranged in the machine body and located below the maintaining tank. The control module is electrically connected with the rotating module, the lifting module and the curing module, the control module drives the forming platform to immerse in a liquid forming material in the maintaining tank, and the forming platform is driven by the control module to rise relative to the maintainingtank through the lifting module and drives the maintaining tank to rotate through the rotating module, after the curing module is driven by the control module to cure the liquid forming material between the forming platform and the inner bottom of the maintaining tank and a curing layer is obtained, so that the curing layer can be separated from the inner bottom of the maintaining tank and formedon the forming platform. The stereoscopic printing device is of a simple curing layer detaching structure to improve the efficiency of stereoscopic printing.
