Abstract
A three-dimensional printing apparatus includes a liquid tank, a curing platform and a light source device. A bearing member of the liquid tank is air proof, and forms an accommodating space with a side wall of the liquid tank. The curing platform is disposed at a first side of the bearing member corresponding to the accommodating space for allowing a workpiece to be cured on a surface thereof. After the accommodating space accommodates a liquid material, a curing light beam provided by a light source device disposed at a second side of the bearing member opposite to the accommodating space cures at least part of the liquid material on a surface of the curing platform via the bearing member. The use of a solid release material between the curing platform and the bearing member may be omitted. Methods for printing and releasing a three-dimensional workpiece are also provided.
