Abstract
A three-dimensional (3D) printing includes a rigid base, a build vessel supported on the rigid base, and an imaging module. The build vessel includes a lower frame structure, a transparent plate supported by the lower frame structure, a transparent sheet supported above the transparent plate, a vented housing supported by the lower frame structure, a desiccant disposed within the vented housing, and a vessel wall coupled to the lower frame structure. A fixed or variable fluidic region is defined between the transparent plate and the transparent sheet. The vented housing includes openings fluidically communicating with the fluidic region to allow the desiccant to deplete vapor from the fluidic region. The vessel wall and transparent sheet are configured to provide an upward facing reservoir. The imaging module is supported by the rigid base and configured to selectively image the photocurable liquid over a build plane above the transparent sheet.
