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.

Wiper arrays for use in additive manufacturing apparatuses

A method for forming an object includes moving a recoat assembly () in a coating direction over a build material, wherein the recoat assembly () comprises a first roller () and a second roller () that is spaced apart from the first roller; rotating the first roller () of the recoat assembly in a counter-rotation direction, such that a bottom of the first roller moves in the coating direction; contacting the build material with the first roller of the recoat assembly, thereby fluidizing at least a portion of the build material; irradiating, with a front energy source () coupled to a front end of the recoat assembly, an initial layer of build material positioned in a build area; subsequent to irradiating the initial layer of build material, spreading the build material on the build area with the first roller, thereby depositing a second layer of the build material over the initial layer of build material; and subsequent to spreading the second layer of the build material, irradiating, with a rear energy source () positioned rearward of the front energy source, the second layer of build material within the build area.

Recoat assemblies for additive manufacturing systems and methods for using the same

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.

Additive manufacturing apparatuses and methods for using the same

A method for producing a component layer-by-layer include the steps of: depositing a layer of particulate material having a first area over a build platform; applying a radiant-energy-curable binder to the layer so that a selected portion of the first area is uniformly coated with binder; selectively curing a second area of the layer smaller than the selected portion of first area, using an application of radiant energy in a specific pattern that defines the geometry of a cross-sectional layer of the component; and repeating the steps of depositing, applying, and curing for a plurality of layers until the component is complete.
