Three dimensional printing system with resin containment solution

A fluid spill containment vessel for a three dimensional printing system having a resin vessel positioned above a light engine, the fluid spill containment vessel for capturing resin that spills from the resin vessel, the fluid spill containment vessel comprises:

• a housing for containing the spilled resin and having a pair of opposing upper lips for removably mounting the fluid spill containment vessel between the light engine and the resin vessel;
• a transparent window that aligns with an optical path between the light engine and the resin vessel to allow pixelated light to travel from the light engine, through the transparent window, and to the resin vessel;
• and
• a fluid barrier wall surrounding at least part of the transparent window and configured to reduce an amount of spilled resin required to occlude the pixelated light.

A three dimensional printing system for fabricating a three-dimensional article of manufacture comprising:

• a vertical support member;
• a support plate coupled to the vertical support and having an upper side and a lower side;
• a resin vessel supported by the support plate;
• a light engine supported below the support plate and configured to project pixelated light to the resin vessel;
• and
• a fluid spill containment vessel supported between the resin vessel and the light engine to capture resin that spills from the resin vessel, the fluid spill containment vessel comprises:
• a housing for containing the spilled resin;
• a generally horizontal transparent window for allowing the pixelated light to project up through the fluid spill containment vessel and to a transparent sheet;
• and
• a fluid barrier wall surrounding the transparent window to trap a constrained volume of spilled resin above the transparent window before the spilled resin can fill remaining portions of the housing.
