Abstract (en)

[origin: WO2015197039A1] The present invention relates to a device and a method for the rapid manufacturing of components through the layered bonding of powder particles to each other and/or to a semi-finished product or substrate already produced, using selective interaction of the powder particles with a high-energy beam (13), wherein, during the bonding of the powder particles into a layer made of powder particles with the aid of the high-energy beam, a gas flow (7) which has a current direction having a directional component directed at least partially parallel to the layer of the powder particles is provided across the layer of powder particles and/or the bonding area in the layer of powder particles, wherein the directional component of the gas flow (7) directed at least partially parallel to the layer of powder particles during the bonding of the powder particles in a layer is generated in at least two directions which have oppositely-directed directional components.
