Abstract: A system includes a supply receptacle defining one or more supply receptacle sidewalls and an upwardly-facing receptacle opening, a piston positioned at least partially within the supply receptacle, where the piston, the upwardly-facing receptacle opening, and the one or more supply receptacle sidewalls at least partially define an interior space of the supply receptacle, and the piston is positionable between an extended position, in which the interior space has an extended volume, and a retracted position, in which the interior space has a retracted volume that is greater than the extended volume, and a dosing hopper positioned above and in selective communication with the interior space of the supply receptacle, where the dosing hopper is structurally configured to deliver build material to the interior space.
