Material supply systems for additive manufacturing and methods for using the same

A system comprising:

• a build area positioned along a working surface;
• a supply receptacle defining one or more supply receptacle sidewalls and an upwardly-facing receptacle opening;
• a piston engaged with the one or more supply receptacle sidewalls, wherein:
• the piston, the upwardly-facing receptacle opening, and the one or more supply receptacle sidewalls at least partially define an interior space;
• 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;
• a dosing hopper positioned above and in selective communication with the supply receptacle, wherein the dosing hopper is structurally configured to deliver build material to the interior space and wherein the dosing hopper defines a dosing volume;
• a conveyance hopper in communication with the dosing hopper, the conveyance hopper defining a supply volume, wherein the supply volume is greater than the dosing volume;
• and
• a supply chute positioned between the dosing hopper and the interior space and having a supply chute opening into the interior space positioned below the upwardly-facing receptacle opening, wherein the interior space defines a dose volume defined by the one or more supply receptacle sidewalls, the upwardly-facing receptacle opening, and the supply chute opening.
