1. A three-dimensional printing apparatus adapted for spraying a printing material, the three-dimensional printing apparatus comprises:

  • a nozzle module;

    a printing platform, having a carrying surface, wherein a calibration pattern is disposed on the carrying surface, and the calibration pattern at least comprises a datum path and a first auxiliary path, and wherein a first datum line and a second datum line are arranged to be spaced with a distance to form the datum path, and a first auxiliary line is arranged to be spaced with a distance from one side of the datum path to form the first auxiliary path; and

    a control unit, coupled to the nozzle module, wherein the control unit controls the nozzle module to spray the printing material along the datum path, and correspondingly adjusts a printing speed of the nozzle module in response to a width of coverage of the printing material on the calibration pattern;

    wherein in response to the width of coverage, the control unit adjusts at least one of a nozzle moving speed of the nozzle module and a material supplying speed of the printing material to correspondingly adjust the printing speed of the nozzle module.
