Claim 3:
4. An additive manufacturing system comprising:
a window platform defining a first upper surface comprising an opening;
a build window:
spanning the opening in the first upper surface of the window platform; and
defining a second upper surface;

a projection system configured to project electromagnetic radiation toward the second upper surface of the build window;
a fluid distribution port inset into the first upper surface of the window platform;
a fluid distribution channel:
circumscribing the build window; and
intersecting the fluid distribution port;

an interstitial gasket circumscribing the first upper surface of the window platform;
a separation membrane:
tensioned over the window platform and the build window;
configured to a seal against and cooperate with the interstitial gasket to define an interstitial region between the second upper surface of the build window and a lower surface of the separation membrane; and
configured to separate from the build window in response to injection of fluid, via the fluid distribution port and the fluid distribution channel, into the interstitial region.
