Multi-model three-dimensional printing device and method

The invention discloses a multi-model three-dimensional printing device and method. Ascending-and-descending blocks are located above a flexible working platform. A printing nozzle is arranged above the ascending-and-descending blocks. The top faces of the ascending-and-descending blocks serve as a printing basic plane. All the ascending-and-descending blocks are closely arrayed on the plane to form a modularized printing platform. The flexible working platform comprises a base shell and driving assemblies. Each ascending-and-descending block is connected with the corresponding driving assembly. The method comprises the steps that three-dimensional models of multiple objects are guided in; the horizontal direction establishment pose of each three-dimensional model is determined; the establishment positions, the printing sequence and the switching path of the three-dimensional models are planned; the height of the printing basic plane is set; and the three-dimensional models are sequentially printed one by one
