Beschreibung
Zusammenfassung:	A device for applying powder layers across a substrate or atop an existing powder bed is disclosed. The device has particular utility in embodiments which are adapted for use in depositing powder layers for three-dimensional printing and as part of a three-dimensional printing apparatus. The device utilizes a conveyor belt to transfer powder from a powder reservoir and deposit it upon powder bed or other substrate. In some embodiments, the device utilizes a conveyor belt in conjunction with a powder deflector to transfer powder from a powder reservoir and deposit it upon powder bed or other substrate. In some embodiments the conveyor belt has a downwardly inclined section. In some embodiments, a downwardly inclined chute is used in conjunction with the conveyor belt.
