SYSTEMS AND METHODS FOR ADDITIVE MANUFACTURING USING PIXEL SHIFTING

An additive manufacturing apparatus (10) includes a support plate (14) defining a window (16) and a resin support (26) configured to support an uncured layer (68) of resin. A stage (18) is configured to hold one or more cured layers of the resin to form a component (12) positioned opposite a support...

Zusammenfassung:	An additive manufacturing apparatus (10) includes a support plate (14) defining a window (16) and a resin support (26) configured to support an uncured layer (68) of resin. A stage (18) is configured to hold one or more cured layers of the resin to form a component (12) positioned opposite a support plate (14). A radiant energy device (20) is positioned on an opposite side of the resin support (26) from the stage (18) and is operable to project radiant energy in a grid (78) through the window (16). The grid (78) and/or pixels thereof are intelligently shifted to efficiently print one or more layers of a component (12).
