1. A three-dimensional printing apparatus, comprising:

  • a processing unit, configured to read and process a digital three-dimensional model information;

    a base, having a carrying surface;

    a three-dimensional display unit, coupled to and controlled by the processing unit and configured to display a digital three-dimensional image related to the digital three-dimensional model information on the carrying surface for previewing, wherein the three-dimensional image is corresponding to a three-dimensional object related to the digital three-dimensional model information; and

    a printing head, disposed above the base and coupled to the processing unit, wherein the processing unit controls the printing head to dispense a base material on the carrying surface layer by layer along an image contour of the three-dimensional image so as to form the three-dimensional object according to the digital three-dimensional model information, wherein an object contour of the three-dimensional object and the image contour substantially appear to be layer by layer coincided with each other in a space above the carrying surface at where the three-dimensional object is formed.
