Einrichtung zum Zuführen von Pulver für eine Lasersintereinrichtung

摘要

Disclosed is a device for introducing powder to a flat surface (1) of a device which is used to produce a three-dimensional object layer by layer, especially a laser sintering device. The inventive device comprises a first coating device (3) which can be moved backwards and forth by means of a drive mechanism in a second direction extending across a first direction between a first lateral position and a second position located on the opposite side thereof. Said device can be filled with powder in at least one of the positions thereof. In order to simply the device and in order to improve operation, the coating device (3) is provided with a slit (6) which extends over the entire width thereof and is open both at the top and below, in addition to respective smoothing elements (7,8) disposed on the opposite ends of the surface. A storage chamber (9) is arranged above the coating device (3) in a final lateral position thereof, whereby the volume of said storage chamber is at least equal to the volume of the slit volume located therebelow at each point along the entire width thereof.
