Abstract: An additive manufacturing system including a base assembly and a tray assembly. The base assembly includes a build window, substantially transparent to electromagnetic radiation; a projection system configured to project electromagnetic radiation toward an upper surface of the build window; and a tray seat arranged around a perimeter of the build window. The tray assembly is configured to engage with the base assembly in an engaged configuration and includes: a tray structure defining a registration feature configured to engage the tray seat to locate an aperture proximal to the upper surface of the build window in the engaged configuration; and a separation membrane that is configured to laminate across the upper surface of the build window in response to an evacuation of gas from an interstitial region and configured to separate from the build window in response to injection of gas into the interstitial region.

Abstract: One variation of a system includes a chassis: defining a set of platform mounts defining a pivot axis; and a slot arranged between the set of platform mounts and configured to transiently retain a filter receptacle below the pivot axis. The system further includes a tray platform: pivotably coupled to the set of platform mounts; defining a tray-receiving section configured to receive a tray defining a fluid release point and configured to retain a volume of resin; and defining a set of supports arranged about the tray-receiving section and configured to locate the fluid release point at the fixed pivot location. The system further includes a tray lock coupled to the platform and configured to transiently generate a magnetic field to draw the tray against the tray-receiving section and cooperate with the set of tray supports to constrain the fluid release point to the fixed pivot location.
