摘要： An additive manufacturing apparatus includes a feed module and a take-up module that are configured to operably couple with a foil. A stage is configured to hold one or more cured layers of a resin that form a component. A radiant energy device is positioned opposite to the at least one stage. The radiant energy device is operable to generate and project radiant energy in a predetermined pattern. An actuator is configured to change a relative position of the at least one stage and the foil. An accumulator is positioned between the feed module and the take-up module. The accumulator is configured to retain an intermediate portion of the foil to allow a first portion of the foil upstream of the accumulator to move at a first speed and a second portion of the foil downstream of the accumulator to move at a second speed during a defined time period.

摘要： An additive manufacturing apparatus includes a first print module includes a first stage configured to hold a first component and a first radiant energy device. The resin support is configured to be positioned between the first stage and the first radiant energy device. A second print module includes a second stage configured to hold a second component and a second radiant energy device. The resin support is configured to be positioned between the second stage and the second radiant energy device. A control system is configured to translate the resin support based on a condition of the first print module and the second print module through the first print module and the second print module.

摘要： 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.

摘要： 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.
