Abstract: An additive manufacturing apparatus includes a support plate and a foil supporting an uncured layer of a resin. A stage is configured to hold a component of one or more cured layers of the resin. One or more actuators is operable to move the stage away from the support plate in a Z-axis direction. A radiant energy device is positioned opposite the stage such that the support plate is positioned between the radiant energy device and the stage. A foil interaction device includes a first pneumatic actuation zone and a second pneumatic actuation zone. Each of the first and second pneumatic actuation zones is configured to apply a force on a surface of the foil. The first and second pneumatic actuation zones are fluidly separable and configured to apply varied pressures relative to one another to the surface of the foil.

Abstract: An additive manufacturing apparatus is provided herein that includes a resin support configured to support a resin. A support plate includes a window. A stage is configured to hold one or more cured layers of the resin to form a component. Each cured layer is formed with the stage in a respective cure position. A radiant energy device is positioned on an opposite side of the resin support from the stage and is operable to generate and project radiant energy in a patterned image through the window. An actuator is operably coupled with the stage and is configured to move the stage in a Z-axis direction to place the stage in a removal position. The component contacts one of the resin support or the resin supported by the resin support in the removal position.

Abstract: An additive manufacturing apparatus includes a stage configured to hold a component. A radiant energy device is operable to generate and project radiant energy in a patterned image. An actuator is configured to change a relative position of the stage relative to the radiant energy device. A resin management system includes a material deposition assembly upstream configured to deposit a resin on a resin support. The material deposition assembly includes a reservoir configured to retain a first volume of the resin and define a thickness of the resin on the resin support as the resin support is translated in an X-axis direction. The material deposition assembly further includes a vessel positioned above the reservoir in a Z-axis direction and configured to store a second volume of the resin. In addition, the material deposition assembly includes a conduit configured to direct the resin from the vessel to the reservoir.

Abstract: An additive manufacturing apparatus includes a support plate and a stage configured to hold a component formed of one or more cured layers of a resin. An actuator assembly is configured to change a relative position of the stage relative the support plate. A radiant energy device is positioned opposite to the stage such that it is operable to generate and project radiant energy in a pattern. A peeling device is positioned downstream of the window. The actuator assembly is configured to move the stage simultaneously with a resin support over the peeling device in an X-axis direction.
