Abstract: A removal method for an object of manufacture after a powder-based additive manufacturing process. The object is made in a build box, in which powder is fused using a powder-based additive manufacturing process. A fluid is delivered into the build box, the fluid having a pressure and composition suitable for fluidizing powder not used for manufacture of the object. This results in fluidization of the powder in the build box, from which the object may easily be extracted.

Abstract: In a general aspect, a pressure regulating device helps achieve a correct inflation pressure of an inflatable object. In some aspects, an inflation device includes an inlet, and outlet, and a vent port. The inflation device also includes one or more interior surfaces that define a gas-delivery pathway fluidly-coupling the inlet and the outlet. A flow restriction is disposed along the gas-delivery pathway between the inlet and the outlet. Moreover, an opening is disposed along the gas-delivery pathway adjacent the flow restriction and downstream thereof. The inflation device also includes a gas-exhaust pathway fluidly-coupling the opening and the vent port. A first chamber of the gas-exhaust pathway is in fluid communication with the opening, and a second chamber of the gas-exhaust pathway is in fluid communication with the vent port. A pressure-relief valve is configured to control gas flow between the first chamber and the second chamber.
