Claim Text:
1. A device for manufacturing three-dimensional object by solidification of layers of a powder material at those positions corresponding to the respective cross-section of the object, said device including: an application device for applying powder in layers, the application device being movable over a building area and having: a first longitudinal wall and a second longitudinal wall that are connected to one another via side walls so as to form a supply chamber having a longitudinal direction substantially transverse to a direction of movement of the application device, said first and second longitudinal walls being substantially longer than said side walls, a device for fluidizing the powder material by means of a fluidizing gas that is fed to the application device, and a device for an open loop and/or closed loop control of the pressure and/or the flow rate of said fluidizing gas, the device for manufacturing three-dimensional object further comprising an irradiation device for irradiating powder for solidification of the powder material.
