Abstract
A 3D printing system includes a build vessel, a carriage, and a light engine. The build vessel includes a vessel base having a downward extending tension ring that tensions a transparent sheet. The transparent sheet laterally bounds a build plane that is defined over orthogonal lateral axis X and Y. The carriage includes a roller that extends between two opposing sides of the tension ring. The roller exerts an upward force on the transparent sheet and the two opposing sides of the tension ring. The vertical constraint of the roller biased against the tension ring provides a location and improved planarity of a supported portion of the transparent sheet adjacent to the roller. The light engine light engine is configured to selectively apply radiation to a projected area of the build plane through the supported portion of the transparent sheet.
