Abstract: A 3D printing system includes a machine chassis, a vessel support, a gas pressure source, a build vessel, a light engine, and a lateral movement mechanism. The build vessel is supported by the vessel support and includes a transparent sheet. The vessel support includes a carriage having a top surface. The carriage is configured to be positioned along a lateral X-axis under the transparent sheet. The carriage defines an optical path and a fluid channel that at least partially surrounds the optical path. The gas pressure source is coupled to the fluid channel. Gas flowing from the gas pressure source and out of the fluid channel is configured to maintain a vertical spacing between the top surface of the carriage and the transparent sheet. The lateral movement mechanism translates and positions the carriage and light engine together along the lateral X-axis.

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.

Abstract: A 3D printing system includes a machine chassis, a build vessel, a carriage, an actuator, a build platform, and a light engine. The build vessel is supported by the machine chassis and contains a photocurable liquid. The build vessel includes a downward extending tension ring that tensions a transparent sheet and defines a datum plane. The carriage supports a glass plate and a roller. The carriage is configured to press the roller against the two opposing sides of the tension ring. The actuator is configured to vertically position an upper surface of the glass plate in two positions including (U) an upper position at which the upper surface of the glass plate is coplanar with the datum plane and (L) a lower position in which the upper surface of the glass is spaced away from the datum plane.
