A reclamation system for an additive manufacturing apparatus can include a collection structure configured to remove at least a portion of the resin from a foil. A containment vessel can be configured to retain the resin removed from the foil. A drain can direct the resin from the containment vessel to a reservoir.

Reclamation system for additive manufacturing

Additive manufacturing apparatuses, components of additive manufacturing apparatuses, and methods of using such manufacturing apparatuses and components are disclosed. An additive manufacturing apparatus may include a recoat head for distributing build material in a build area, a print head for depositing material in the build area, one or more actuators for moving the recoat head and the print head relative to the build area, and a cleaning station for cleaning the print head.

Additive manufacturing apparatuses and methods

Embodiments of the present disclosure are directed to additive manufacturing apparatuses, cleaning stations incorporated therein, and methods of cleaning using the cleaning stations.

An apparatus includes a printing head () comprising jet nozzles () spaced apart from one another, where a distance from a first jet nozzle to a second jet nozzle positioned adjacent the first jet nozzle defines a jet-spacing, a printing head position control assembly includes a first actuator assembly () to move the printing head along the longitudinal axis and a second actuator assembly () to move the printing head along a latitudinal axis, and an control unit communicatively coupled to the printing head position control assembly. The control unit causes jet nozzles to dispense drops of binder () while the printing head traverses a first pass trajectory along the longitudinal axis in a first direction, indexes the printing head to a second pass trajectory along the latitudinal axis, and causes jet nozzles to dispense drops of binder while the printing head traverses the second pass trajectory along the longitudinal axis in a second direction.

An additive manufacturing apparatus can include a stage configured to hold a component formed by one or more layers of resin. A support plate can be positioned above the stage. A radiant energy device can be positioned above the stage. The radiant energy device can be operable to generate and project energy in a predetermined pattern. A feed module can be configured to operably couple with a first end portion of a resin support and can be positioned upstream of the stage. A take-up module can be configured to operably couple with a second end portion of the resin support and can be positioned downstream of the stage.

Additive manufacturing system

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.
