Abstract

A three-dimensional printing system includes a light source unit, at least one image-capturing module, a processing unit and a printing device. The image-capturing module includes an image-capturing unit and a focus-adjusting lens group. The processing unit controls a zooming lens to change a shooting focal length and controlling multiple images of the object to be measured captured by the image-capturing unit under the different shooting focal lengths, wherein each of the plural images includes focused and unfocused local images therein, and the processing unit calculates out a three-dimensional profile data of the object to be measured according to the focused local images in the images and the shooting focal lengths corresponding to the focused local images. The printing device prints multiple cross-sectional profiles corresponding to the object to be measured. Further, a method for three-dimensional printing is also provided.
