The layer construction method comprises at least the following steps: a) applying at least one powder layer of a material to at least one construction and joining zone of at least one movable construction platform; b) locally solidifying the material to form a component layer, wherein the material is selectively scanned along scan lines by at least one energy beam and fused; c) lowering the construction platform layer by layer by a predefined layer thickness; and d) repeating the steps a) to c) until the component region is complete. In step b), a distance hbetween at least two central lines of neighboring scan lines in at least one component layer is adjusted in accordance with Formula I0.85≤≤1.00  (I)wherein brepresents a minimum melt pool width of the scan lines.
