Abstract: A method of removing a printed item from a 3D printer. The method may include loading a print bed into a 3D printer, where a bottom surface of the print bed may be removably attached to a print stage. The printed item may be printed by a tool head of the 3D printer atop the print bed. The print bed together with the printed item may be unloaded from the 3D printer upon completion of the printing, where unloading the print bed may include detaching the print bed from the print stage. The printed item may then be released from the print bed.

Abstract: A manual subcutaneous jet injector includes an injector body having an injection portion provided with an injection system including an injection fluid volume fluidically connected to a subcutaneous injector outlet, and a pumping portion. The pumping portion includes an interior chamber having a pumping portion and a pressure chamber portion fluidically connected to the injection fluid volume. A manually operated injector pump is arranged in the pumping portion. At least one one-way valve is arranged between the pumping portion and the pressure chamber portion, the one-way valve including an inlet end and an outlet end. A piston is arranged in the pumping portion at the inlet end of the one-way valve.

Abstract: A method of manually charging a subcutaneous jet injector includes shifting a piston arranged within a pressure chamber portion of the subcutaneous jet injector, forcing a fluid through a one-way valve with the piston into a chamber of the subcutaneous jet injector, pressurizing the fluid in the chamber creating a pressurized fluid, forcing the pressurized fluid in the chamber into another chamber including a bolus dose of injectable fluid, and directing the bolus dose of injectable fluid from the subcutaneous jet injector with the pressurized fluid.
