| description | The present invention relates to device and a method for the additive manufacture of workpieces and use of same. Workpieces that can be manufactured in accordance with the method include, for example, turbine blades, but any other geometries can also be produced. The device for the additive manufacture of workpieces comprises at least one radiation source, at least one lowerable lifting surface, at least one material reservoir for a raw material in powder form and at least one process chamber, wherein the lifting surface can be can be moved between an initial position in the region of influence of the radiation source and an end position below the initial position, and a construction volume for the additive manufacture of workpieces extends between the initial position and end position, wherein at least one filler body is arranged in the construction volume and occupies a partial volume of same, and the lifting surface has an exterior shape that enables the lifting surface to be lowered relative to the filler bodies through the construction volume from the initial position to the end position. |
