1. A three-dimensional printing system comprising:
a rigid base;
a build vessel supported on the rigid base, the build vessel including:
a lower frame structure;
a transparent plate supported by the lower frame structure;
a transparent sheet supported by the lower frame structure above the transparent plate with a fixed or variable vertical fluidic region between the transparent plate and the transparent sheet;
a vented housing supported by the lower frame structure, the vented housing including openings fluidically communicating with the fluidic region;
a desiccant disposed within the vented housing; and
a vessel wall coupled to the lower frame structure, the vessel wall and transparent sheet configured to provide an upward facing reservoir; and
an imaging module supported by the rigid base and configured to selectively image a photocurable liquid over a build plane above the transparent sheet.
