US Patent 8034279 Method and device for manufacturing a three-dimensional object

A method for manufacturing a three-dimensional object by successively solidifying layers of a building material at positions in the respective layer corresponding to the cross-section of the object is provided, wherein at least a partial region of a layer is solidified such that a pattern is generated, which pattern contains a plurality of substantially parallel solidification lines (V, S), and at least a partial region of a subsequent layer is exposed such that a pattern is generated, which pattern contains a plurality of substantially parallel solidification lines (V, S) that are rotated with respect to the solidification lines of the pattern of the previous layer by an angle (α) that differs from 180°, 90° and 45°.
