The invention discloses a rapid and continuous ultraviolet light curing stereoscopic prototyping system and method. The rapid and continuous ultraviolet light curing stereoscopic prototyping system comprises upper computer control software, an embedded controller module, an ultraviolet optical engine module, a prototyping lifting platform module, a position detection module, a resin container module and a focusing assisting module. During rapid prototyping, an ultraviolet optical engine and a stepper motor are controlled to work synchronously through mutual cooperation of the upper computer control software and the embedded controller module, pictures are projected to the bottom of a prototyping platform by the ultraviolet optical engine through an oxygen semi-permeable membrane at the bottom of a resin pool, the stepper motor drives the prototyping platform to move upwards continuously according to slicing parameters, thus, the time required for curing of each layer of a model is shortened, and the curing prototyping speed is increased.
