Abstract
A three-dimensional printing apparatus and a printing method thereof are provided. The three-dimensional printing apparatus includes a tank, a movable platform, a light source module, and a controller. The bottom of the tank includes an irradiated area and a non-irradiated area. The movable platform is movably disposed above the tank. The light source module is disposed under the tank and only provides light to the irradiated area to irradiate a liquid-formation material. The controller controls the movable platform to move along a first axis direction, such that at least one layer object of a three-dimensional object is cured on the movable platform layer by layer. The layer object is composed of object sections. During a period of forming one layer object, the controller controls the movable platform to move on a horizontal plane, such that the object sections of the layer object are cured sequentially above the irradiated area.
