Abstract
A layer-by layer method for additive manufacturing that includes: photocuring a first volume of resin to form a layer of a build at an upper surface of a separation membrane laminated over a build window; injecting a fluid into an interstitial region between the separation membrane and the build window; retracting the build from the build window; evacuating the fluid from the interstitial region; and photocuring a second volume of liquid resin to form a subsequent layer of the build between an upper surface of a separation membrane and the previous layer of the build.
