Abstract: A build material escapement assembly for an additive manufacturing system includes a retaining plate for coupling the build material escapement assembly to the additive manufacturing system. A base having a plurality of ports is disposed beneath the retaining plate, and a support frame is disposed within the base. A diaphragm is disposed around the base, and a retractable plate is disposed between the support frame and the diaphragm. A top plate is further coupled to the retractable plate through the diaphragm and a plurality of connectors are coupled to the plurality of ports of the base. The base, support frame, diaphragm, retractable plate, and top plate define a cavity, and the top plate is movable between a retracted position by applying a negative pressure and an extended position by applying positive pressure to the cavity via the plurality of connectors.

Abstract: Additive manufacturing assemblies, printing assemblies, and methods for utilizing same are provided. A method includes providing a linear traversing stage (212) movable in a direction transverse to a rail (104) extending along a working axis of the additive manufacturing apparatus, and coupling a printing assembly (150) to the linear traversing stage (212) such that the printing assembly is movable along the linear traversing stage in a direction transverse to the working axis. In embodiments, the printing assembly includes a housing (201) including a printing head (154). At least one adjustment member (232) may be extended or retracted through a yaw bar (224) to rotate the housing. In embodiments, a printing head receptacle (502) may be provided for coupling the printing assembly to the rail. In embodiments, the yaw bar (224) may be provided between the housing and the printing head receptacle (502) for rotating the printing assembly relative to the printing head receptacle.

Abstract: A grid of phased array transducers includes a piezoelectric layer and a plurality of ground contact traces. The piezoelectric layer includes a first side and a second side. The plurality of ground contact traces is disposed on the first side of the piezoelectric layer along an elevational direction, where each ground contact trace of the plurality of ground contact traces extends along an azimuthal direction. Further, each phased array transducer of the grid of phased array transducers is disposed between an adjacently disposed pair of ground contact traces of the plurality of ground contact traces. Moreover, each phased array transducer includes at least a portion of at least one ground contact trace of a corresponding pair of ground contact traces, and where each phased array transducer includes a plurality of transducer elements.
