Abstract
A three dimensional printing apparatus is provided. The three-dimensional printing apparatus includes a tank, a rotatable platform, a light source module and a controller. The rotatable platform is elevatably disposed above the tank, and the light module is disposed under the tank. When the controller controls the rotatable platform elevating to a height along an axis direction, the controller controls the rotatable platform rotating a plurality of rotating angles in sequence around the axis direction and controls the light source module irradiating liquid-formation material, so as to sequentially solidify a plurality of object sections of a single layer object.
