Abstract
A 3-D printing apparatus of the invention includes a process unit, a 3-D display unit, a base and a printing head. The processing unit is configured to read and process a digital 3-D model information. The base has a carrying surface. The 3-D display unit is coupled to and controlled by the processing unit and configured to display a digital 3-D image related to the digital 3-D model on the carrying surface for previewing, wherein the 3-D image is corresponding to a 3-D object related to the digital 3-D model. The printing head is disposed above the base and coupled to the processing unit, wherein the processing unit controls the printing head to dispense a base material formed on the carrying surface layer by layer so as to form the 3-D object according to the digital 3-D model information and following an image contour of the 3-D image.
