THREE DIMENSIONAL PRINTING APPARATUS AND PRINTING METHOD THEREOF

摘要

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.

1. A three-dimensional printing apparatus, comprising:
a tank configured to contain a liquid-formation material, wherein a bottom of the tank comprises an irradiated area and a non-irradiated area; a movable platform disposed movably above the tank; a light source module disposed under the tank and providing light to the irradiated area to irradiate the liquid-formation material; and a controller coupled to the light source module and the movable platform and controlling the movable platform to move above the tank along a first axis direction, so as to cure at least one layer object of a three-dimensional object layer by layer on the movable platform, wherein the at least one layer object consists of a plurality of object sections, wherein, during a period of forming the at least one layer object, the controller controls the movable platform to move on a horizontal plane, so as to cure the object sections of the at least one layer object sequentially above the irradiated area.
