Vessel for receiving a stereolithographic resin, a device at which a stereolithographic object is made, a method for making a stereolithographic object and a method for making a vessel for receiving a stereolithographic resin

A vessel for receiving a stereolithographic resin, the vessel comprising:

• a casting frame comprising at least one perimeter exterior wall defining a plurality of peripheral gas ports in fluid communication with an atmosphere, the plurality of gas ports extending between opposite sides of the at least one perimeter exterior wall;
• an oxygen permeable element comprising a cast oxygen permeable substrate cast within the casting frame and the plurality of gas ports, the oxygen permeable element comprising a stereolithographic resin receiving surface that is an interior vessel surface, the oxygen permeable substrate comprising at least one marginal surface separate from the stereolithographic resin receiving surface, wherein the at least one marginal surface is flush with an external surface of the at least one perimeter exterior wall for passive ingress of oxygen from the atmosphere and transport of the oxygen ingressed to the stereolithographic resin receiving surface to enable formation of a layer of oxygenated stereolithographic resin.
