Abstract
A three dimensional printing system includes a resin vessel, a light engine, and a fluid spill containment vessel. The resin vessel is for containing resin and has a transparent sheet on a lower side that provides a lower bound for the resin. The light engine is disposed below the resin vessel for projecting pixelated light up through the transparent sheet. The fluid spill containment vessel is disposed between the resin vessel and the light engine to capture resin that spills from the resin vessel. The fluid spill containment vessel includes a housing for containing the spilled resin, a transparent window for allowing the pixelated light to project up through the fluid spill containment vessel and to the transparent sheet, and a fluid barrier wall surrounding at least part of the clear window and configured to reduce an amount of spilled resin required to occlude the pixelated light.
