    Abstract: A 3D printer is configured to print a 3D part. The 3D printer includes a print head carried by a head gantry and configured to operably move the print head along planar tool paths. The 3D printer includes at least one head gantry actuator coupled to the head gantry and configured to move the print head in a plane and a print head actuator coupled to the print head and configured to move the print head in a direction substantially orthogonal to the plane. A sensor is fixedly mounted to the print head and configured to output a first signal that is directly or indirectly related to an acceleration of the print head, and a gyroscope is fixedly mounted to the print head and configured to output a second signal related to a rotational position of the print head. The 3D printer includes a controller configured to determine a rotational position error of the print head relative to a predetermined position based on the first signal and the second signal and to output one or more signals to the at least one head gantry actuator and/or the print head actuator to compensate for the rotational position error of the print head.

    Abstract: A consumable assembly for supplying filament to a 3D printer having two or more receptacles having different geometric configurations, the 3D printer builds parts by material extrusion. The consumable assembly includes a container configured to retain a supply of a first filament, and a first filament guide tube having a length, the first filament guide tube having an inlet end attached to the first container and an outlet end, The consumable assembly includes a key having a geometric configuration allowing the key to be plugged into only one receptacle of the two or more receptacles of the 3D printer, the key comprising a conduit having an entrance and an exit, a coupling portion, and an engagement portion, wherein the entrance to the conduit is coupled to the outlet end of the first filament guide tube to thereby form a closed filament path from the first container to the 3D printer.

    Abstract: An additive manufacturing system includes a gantry configured to move in a build plane. A platen is configured to support a part being built in a layer by layer process and wherein the platen is configured to move in a direction substantially normal to the build plane. A head carriage is carried by the gantry wherein the head carriage includes ferromagnetic material. The system includes at least one print head where the print head includes a housing and one or more magnets attached to the housing wherein the at least one print head is configured to be coupled to the head carriage through a magnetic coupling between the one or more magnets and the ferromagnetic material such that the print head is configured to move rotationally relative to the head carriage.

    Abstract: A support structure removal system comprising a vessel and a second component. The vessel comprises a vessel body, a porous floor configured to retain a three-dimensional part, and an impeller rotatably mounted below the porous floor. The second component comprises a surface configured to operably receive the vessel, and a rotation-inducing assembly located below the surface, where the rotation-inducing assembly is configured to rotate the impeller with magnetic fields when the vessel is received on the surface of the second component to agitate and direct flows of an aqueous fluid through the porous floor.
