摘要： A method of manufacturing a target component (150) is disclosed. The method includes inputting (302), into an additive manufacturing system (100), instructions for manufacturing a desired target component (150), wherein the target component (150) includes at least one internal channel (152); inputting a location of at least one port (160) to be formed that extends from an external surface (151) of the target component (150) to the at least one internal channel (152); printing (306), using the additive manufacturing system (100), the target component (150) including the at least one port (160) to form a green body target component (150); and depowdering (308) the at least one internal channel (152) by accessing the at least one port (160) formed on the green body target component (150) to facilitate removing any residual powder from the at least one internal channel (152).

摘要： A system and method for demolding an additively manufactured component includes generating a shockwave in at least one of the additively manufactured component and the substrate upon which the additively manufactured component is built and applying a tensile stress at an interface between the additively manufactured component and the substrate to separate at least a portion of the additively manufactured component from the substrate along the interface in response to the tensile stress.

摘要： A method of three-dimensional printing, comprises: establishing a relative motion between a printing head and a tray while operating said printing head to dispense, via a plurality of nozzle arrays, layers of building material formulations according to the shape of an object, said printing head comprising a manifold having a plurality of channels conveying building material formulations from cartridges to separate nozzle arrays; and for at least one of said channels, switching building material formulation in said channel by disconnecting said channel from a first cartridge, discarding from said channel a first building material formulation, and connecting said channel to a second cartridge containing a second building material formulation, said switching being either between passes or during a pass of said printing head relative to said tray.

摘要： A fluid containment system (200) within an additive manufacturing system (100) comprises a body (202) having a set of panels and seals that define an interior cavity (214). One or more fluid supply sources are fluidly coupled to the interior cavity (214); the one or more fluid supply sources (210) provide at least one fluid to the cavity (214). A sensor (280) is positioned within the cavity (214), and the sensor (280) is configured to detect a vapor threshold within the interior cavity (214). The vapor is formed from an evaporated portion of the at least one fluid within the cavity (214). A controller (400) is communicatively coupled to the sensor (280), and the controller (400) is configured to provide control signals for directing fluid movement of the at least one fluid based on one or more signals received from the sensor (280).
