A stereolithography 3D (three-dimensional) printer and a method of adjusting temperature of printing materials thereof are provided. The stereolithography 3D printer has a material tank for accommodating print materials, a light module, a temperature-adjusting module, a temperature-sensing module, and a curing platform. The stereolithography 3D printer executes a procedure of controlling temperature for adjusting a temperature of the print material if a sensed temperature doesn't reach a default value, and executes a procedure of 3D printing for manufacturing a 3D physical model by using the print material whose temperature had been adjusted. The printing quality of the 3D physical models can be effectively improved via controlling the temperature of the print materials.
