Abstract

A 3D printing apparatus with a radiation source, a workbench, and a liquid tank, wherein a workbench for supporting a three-dimensional object being constructed, and a liquid tank for containing a polymerizable liquid for constructing a three-dimensional object. The apparatus also includes a cover plate which is located in the liquid tank or on the top of the liquid tank; the radiation source irradiates from above the cover plate. The cover plate is an element transparent to the radiation source; and the lower surface of the cover plate is a covering surface which remains in contact with the polymerizable liquid during the printing process.
