Systems and methods for processing debris from job sites are disclosed. Carts for receiving the debris are also disclosed. Each cart has a base, a plurality of wheels extending downwardly from the base relative to a vertical axis, and a plurality of walls extending upwardly from the base. The walls and the base of each cart cooperate to define a debris-receiving space. The carts can be engaged by a lifting apparatus that rotates along an arcuate path to position the carts in an unloading position.

A powder feed mechanism for a three-dimensional printer in which a heap of powder is drawn up from a powder container to be spread across a material bed rather than dropped or deposited on it. The mechanism comprises a carrier arm that moves through a powder chamber, and a support platform for carrying a heap of powdered build material. The support platform moves with the carrier arm. The carrier arm moves to a powder delivery position in which the support platform is in a transverse orientation for lying flush with the material bed. This arrangement can reduce the path travelled by the powder from the powder chamber to the material bed and give greater control over the shape of the heap of powder that is to be spread over the material bed.
