Claim:
1. A three dimensional (3D) printing apparatus, used for foil ling and stacking a plurality of modeling layers to form a 3D object, wherein the 3D printing apparatus comprises: a body, having a modeling platform; a transmission module, disposed on the body; and a printing module, a curing module and a laser module, disposed at the transmission module and controlled by the transmission module to move relative to the body, respectively, a liquid modeling material being jetted from the printing module to the modeling platform and being cured by the curing module to form the modeling layers, the laser module moving along a normal direction of the modeling platform according to a condition parameter and providing a laser beam along at least one plane parallel to the modeling platform to cut and trim at least one modeling layer.
