Three-dimensional printing apparatus

摘要

A three-dimensional (3D) apparatus including a processing unit, a base and a printing head is provided. The processing unit is configured to read and process digital 3D model information. The base is coupled to and controlled by the processing unit. The base includes a plurality of heating regions. The processing unit is configured to selectively heat at least one of the heating regions according to the digital 3D model information. The printing head is disposed above the base. The printing head is coupled to and controlled by the processing unit to dispense a thermal melting material layer-by-layer on the heated heating region to form a 3D object related to the digital 3D model information.
