An apparatus is described for producing a three-dimensional object from a powder material which includes powder particles and which is solidifiable by exposure to electromagnetic radiation. The apparatus includes a support having a substantially plane support surface for supporting said object, an applying device for applying a layer of the powder material to the support surface, a radiation device for selectively exposing the powder material to electromagnetic radiation at places corresponding to the object and a discharge electrode for generating an electric field for reducing charge differences on the powder particles.
