Abstract: In embodiments, an additive manufacturing apparatus comprises a chassis assembly and a skin at least partially covering the chassis assembly. The chassis assembly comprises a lower chassis section secured to a low voltage chassis section; an upper environmental chassis section secured to and extending over the low voltage chassis section and the lower chassis section; a high voltage chassis section secured to the upper environmental chassis section and the lower chassis section; and a build receptacle carriage adjustably coupled to the lower chassis section. The skin comprises first and second doors providing access to the low voltage chassis section and the high voltage chassis section; a rear panel providing access to the upper environmental chassis section; a top panel covering a top of the upper environmental chassis section; and at least one hinged door providing access to the lower chassis section.

Abstract: Build receptacles for additive manufacturing apparatuses are disclosed. The build receptacle may comprise a housing comprising a sidewall at least partially enclosing a build chamber. A build platform may be positioned within the build chamber. A position of the build platform may be slidably adjustable within the build chamber in a vertical direction from a lower position to one of a plurality of upper positions and from the one of the plurality of upper positions to the lower position. The build receptacle may further comprise a plurality of heating elements disposed around the build chamber.

Abstract: 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.

Abstract: An actuator assembly for distributing build material and depositing binder material in an additive manufacturing apparatus may comprise an upper support and a lower support spaced vertically spaced from one another. A recoat head actuator may be coupled to a recoat head and one of the upper support and the lower support. The recoat head actuator may include a recoat motion axis. The recoat head actuator effects bi-directional movement of the recoat head on the recoat motion axis. A print head actuator may be coupled to a print head and the other of the upper support and the lower support. The print head actuator may include a print motion axis. The print head actuator effects bi-directional movement of the print head on the print motion axis. The recoat motion axis and the print motion axis are parallel to one another and spaced apart from one another in the vertical direction.

Abstract: Additive manufacturing apparatuses are disclosed. In one embodiment, an additive manufacturing apparatus may comprise a support chassis including a print bay, a build bay, and a material supply bay. Each bay may comprise an upper compartment and a lower compartment. A working surface may separate each of the print bay, the build bay, and the material supply bay into the upper compartment and the lower compartment, wherein: the build bay may be disposed between the print bay and the material supply bay. The lower compartment of the build bay comprises bulkheads sealing the lower compartment of the build bay from the lower compartment of the print bay and the lower compartment of the material supply bay.

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