Patent ID: 7285234

Claim:
A process for layer-by-layer production of a three dimensional body, including repeating the sequence of steps: applying a layer of powder particles, by means of a dispensing device, upon a substrate; subjecting the powder particles to ionized particles ( 7 ) produced by an ionizing device ( 6 ) during falling of the powder particles onto the substrate; brushing the applied layer flat by a flattening device ( 8 ); activating, in defined areas of said layer, an adhesive present on the powder particles and/or in the powder particle layer; solidifying the activated adhesive to adhere powder particles to each other within the layer and to the substrate; and providing at least one further ionizing device ( 6 ′) associated with the flattening device ( 8 ), the further ionizing device ( 6 ′) exposing the applied powder particles to further charged particles ( 7 ′).
