Zusammenfassung:	A three dimensional printing system includes a light engine having a spatial light modulator for curing individual layers of a photocure resin to form a three dimensional article of manufacture. The light engine is configured to: (1) receive a slice image that defines an array of energy values for curing a layer, (2) process the slice image to define an image frame compatible with the spatial light modulator, (3) receive an on signal, (4) activate the first light source in response to the on signal; (5) repeatedly send the first defined image frame to the first spatial light modulator during a defined cure time for the single layer of resin; (6) receive an off signal; (7) deactivate the first light source in response to the off signal; and (8) repeat steps (1)-(7) until the three dimensional article of manufacture is formed.
