Abstract
A three-dimensional printing system includes a support plate and a resin vessel. The support plate defines a central opening and an upper surface. The resin vessel is disposed upon the upper surface of the support plate and includes a substructure and a transparent sheet. The substructure includes a vertical wall and a tension ring that extends inwardly and downwardly from the vertical wall. The tension ring impinges downwardly upon an upper surface of the transparent sheet and tensions the transparent sheet.
