Claim Text:
1. A three-dimensional (3D) printing apparatus, comprising: a processing unit, configured to read and process digital 3D model information; a base, coupled to and controlled by the processing unit, wherein the base comprises a plurality of heating modules and a plurality of heating regions, the heating modules are coupled to the processing unit and disposed corresponding to the heating regions, and the processing unit is configured to control the heating modules to selectively heat at least one of the heating regions according to the digital 3D model information, wherein the digital 3D model information comprises bottom layer distribution data, and the bottom layer distribution data corresponds to a plane coordinate of the base, the processing unit controls the base to heat the at least one heating region to be heated according to the plane coordinate; and a printing head, disposed above the base, wherein the printing head is coupled to and controlled by the processing unit to dispense a thermal melting material layer-by-layer on the at least one heated heating region, so as to form a 3D object related to the digital 3D model information.
