ABSTRACT: A stereolithographic apparatus is disclosed comprising a vat, a working surface in the vat, an elevating mechanism for controlling the level of liquid within the vat relative to the working surface, an illumination source for emitting radiation, and an area array deformable mirror device. The illumination source emits radiation which is operable to harden a stereolithographic liquid, while the deformable mirror device is operable to reflect the incident radiation onto the surface of the liquid. The deformable mirror device can harden an entire lamina of liquid in one brief exposure interval increasing throughout without sacrificing resolution.XX
