Abstract
A device for producing freely formed products through a buildup of layers of powder-form material that is solidified according to specification, comprises a (relatively) lowerable table on the one hand, and a powder feed above the table, a distribution device that spreads the powder in a predetermined thickness over the table, and an energy source that solidifies the powder of each layer on the other hand, that are horizontally movable with respect to each other. In particular, the horizontal movement of the table consists in a rotational movement around an vertical axis, which movement is combined with the descending movement into a spiral movement having a pitch corresponding to the layer thickness, the powder feed, the distribution device, and the energy source being arranged radially around the axis and being continuously active.
