Abstract: A method for providing build material to an additive manufacturing system (100) includes moving the build material (10) from a dosing hopper (240) to an interior space defined by one or more supply sidewalls of a supply receptacle (110) and a piston (130) positioned within the supply receptacle (110), and moving the piston toward a working surface (102) of the additive manufacturing system, thereby moving build material within the interior space to the working surface.

Abstract: A system (100) includes a build area positioned along a working surface (102), a supply receptacle (110) spaced apart from the build area and defining one or more supply receptacle sidewalls and an upwardly-facing receptacle opening (114), a dosing hopper (240) positioned above and in selective communication with the supply receptacle, where the dosing hopper is structurally configured to deliver build material to an interior space (116), and a conveyance hopper (260) in communication with the dosing hopper (240).
