Abstract
An additive manufacturing apparatus includes a stage configured to hold a component. A radiant energy is device operable to generate and project radiant energy in a patterned image. An actuator is configured to change a position of the stage relative to the radiant energy device. A deposition assembly is upstream of the stage and configured to deposit a resin on a resin support. The deposition assembly includes a reservoir housing configured to retain a volume of resin between the upstream wall and the downstream wall. The deposition assembly also includes an application device operably coupled with the reservoir housing. A computing system is operably coupled with the application device. The computing system is configured to intermittently initiate a flush operation between successive layers of the component, wherein the application device is moved from a first position to a second position during the flush operation.
