Patent ID: 7686605

Claim:
A device for manufacturing a three-dimensional object by a layer wise solidification of a building material at the positions in the respective layers that correspond to the object, comprising: a building field, in which the building material in powder form is solidified, an application element that applies the building material in powder form in the form of a layer; and a drive mechanism that moves the application element across the building field in order to apply the layer of the building material, wherein the drive mechanism is designed such that for an application of layers it moves the application element between a first end position on a first side of the building field and a second end position on an opposite second side of the building field on a circular path back and forth, the application element is designed as a blade and that side of the blade, which is facing the building field, applies the building material onto a support device or a previously solidified layer, the application element is connected to the drive mechanism by a holder having a main arm, and the application element has a main body extending substantially in parallel to the main arm of the holder.
