Abstract: An additive manufacturing apparatus includes a support plate including a window. A stage is configured to hold one or more cured layers of the resin to form a component. A radiant energy device positioned on an opposite side of the support plate from the stage and 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 between a curing position and a removal position. The curing position can be offset from the removal position.

Abstract: An additive manufacturing apparatus includes a resin support configured to support a first resin and a second 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 positioned opposite the support plate. 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 assembly is configured to move the stage in a Z-axis direction and in a Y-axis direction.

Abstract: An additive manufacturing apparatus includes a build module. A feed module is configured to support a first portion of a resin support. The first portion of the resin support is supported by a feed mounting panel. A take-up module is configured to support a second portion of the resin support. The second portion of the resin support is supported by a take-up mounting panel and is positioned on an opposing side of the radiant energy device from the feed module. An adjustment assembly is configured to adjust a position of at least one of a feed mandrel within the feed module or a take-up mandrel within the take-up module.

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.

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 toward the stage. An actuator is configured to change a relative position of the stage relative to the radiant energy device. A feed module is configured to support a feed roll of a resin support upstream of the stage about a feed mandrel. A first control device is operably coupled with the feed mandrel. A take-up module is configured to support a take-up roll of the resin support downstream of the stage about a take-up mandrel. A second control device is operably coupled with the take-up mandrel. A computing system is operably coupled with one or more sensors. The computing system is configured to provide commands to at least one of the first control device or the second control device to respectively rotate the first control device or the second control device to obtain a target tension on the resin support.

Abstract: An additive manufacturing apparatus can include a stage configured to hold one or more cured layers of resin that form a component. A radiant energy device can be operable to generate and project radiant energy in a patterned image. An actuator can be configured to change a relative position of the stage relative to the radiant energy device. A reclamation system can be downstream of the stage and can be configured to remove at least a portion of the resin from a resin support. The reclamation system can include a first collection structure configured to accept a resin support therethrough along a resin support movement direction. A first scraper is positioned within the first collection structure. The first scraper has an elongation axis that is offset from the resin support movement direction by an offset angle that is less than 90 degrees.
