An additive manufacturing device and a method of fabricating a 3D object is provided. The device includes a vessel configured to rotate about an axis and a membrane disposed to form a floor of the vessel. A build plate is movable between a first position and a second position, the build plate being positioned a predetermined distance apart from the membrane in the first position. A light source is arranged to direct electromagnetic radiation through the membrane towards the build plate. A processor is provided that is responsive to executable computer instructions for rotating on a periodic, aperiodic, or continuous basis, the vessel to oxygenate the membrane.
