1. A substrate assembly for use with a three-dimensional printer reservoir, the reservoir including a frame defining a cavity adapted to be at least partially filled with a photosensitive liquid, the substrate assembly comprising:
a first layer comprising a permeable film adapted to be configured with a lower portion of the cavity and to hold the photosensitive liquid within the cavity;
a second layer configured below the first layer; and
a third layer comprising a permeable substrate disposed between the first layer and the second layer.
