Claim 10:
11. An additive manufacturing system comprising:
a separation membrane:
tensioned over a build window vertically offset from a tray seat; and
configured to a seal against and cooperate with an interstitial gasket, surrounding the build window, to define an interstitial region between an upper surface of the build window and a lower surface of the separation membrane;

a fluid distribution port:
fluidically coupled to the interstitial region;

a fluid distribution channel:
circumscribing the build window;
intersecting the fluid distribution port; and
cooperating with the fluid distribution port to direct fluid into the interstitial region to separate the separation membrane from the upper surface of the build window;

a projection system configured to project electromagnetic radiation toward the upper surface of the build window.
