1. A three dimensional printing apparatus, comprising:
a tank;
an injecting module, disposed at the tank to inject a liquid forming material into the tank;
a leveling module, movably disposed in the tank;
a curing module, disposed above the tank; and
a control module, electrically connected to the injecting module, the leveling module, and the curing module, wherein the leveling module is controlled by the control module to be moved in the tank, so as to level a surface of the liquid forming material in the tank, and the curing module is controlled by the control module to cure the leveled liquid forming material to form a solidification layer on an inner bottom of the tank,
wherein the surface of the liquid forming material gradually rises relative to the inner bottom of the tank.
