The three-dimensional printing apparatus includes a tank, a platform, a lighting module, a control unit, a photosensitizer coating unit, and an exposure and development unit. The tank is filled with a liquid forming material, and the platform is movably disposed above the tank. The lighting module is used for providing light projecting toward the liquid forming material. The control unit coupled to the platform and the lighting module is configured to control the platform to move along a first direction, such that at least one layer object of a three-dimensional object is cured on the platform by layer. The photosensitizer coating unit is coupled to the control unit and configured to form at least one photosensitizer film on the layer object. The exposure and development unit is coupled to the control unit and configured to expose the photosensitizer film by exposing and developing to color the three-dimensional object.

Stereo lithography three-dimensional printing apparatus and method of forming colored three-dimensional object

The disclosure provides a three-dimensional (3D) printing device including a tank, a forming stage and an irradiation unit. The tank is filled with a liquid forming material. The forming stage is movably disposed at the tank. The irradiation unit is disposed beside the tank and includes an image source and a projecting lens. The image source is used to emit an image beam. The image beam passes through the projecting lens to irradiate and cure the liquid forming material. An entrance pupil position of the projecting lens is ENP and 2000 mm&#x2264;ENP&#x2264;15000 mm. An exit pupil position of the projecting lens is EXP and 2000 mm&#x2264;|EXP|&#x2264;15000 mm.
