Abstract
An additive manufacturing process includes applying a layer of a building material on a building support or an already applied and selectively solidified layer and selectively solidifying the applied layer by electromagnetic radiation or particle radiation. All positions in the layer that correspond to a cross-section of the object are scanned by electromagnetic radiation or particle radiation such that at these positions the powder is melted at least at its surface. At least one cross-section includes an inner region and a surface region. The step of applying a layer and the step of selectively solidifying the layer are repeated until all cross-sections of the object are solidified. At least a portion of the surface region is scanned at least twice before scanning of the inner region starts.
