Claim 0:
1. A method for the generative production of at least one three-dimensional object by successive, selective layer-by-layer solidification of individual construction material layers of a solidifiable construction material, the method comprising:
arranging a plurality of laser diode elements in a plurality of planes arranged one above another and in a specific spatial offset relative to one another in a mounting device disposed directly above a construction plane on which the individual construction material layers are selectively solidified, wherein the plurality of planes arranged one above another comprises an upper plane and a lower plane, wherein respective ones of the plurality of planes comprise a corresponding portion of the plurality of laser diode elements respectively arranged as a matrix having a plurality of contiguous rows and a plurality of contiguous columns, wherein the specific spatial offset provides the corresponding portion of the plurality of laser diode elements in the upper plane arrangement directly above the construction plane through alignment with a corresponding space defined between respective ones of the plurality of laser diode elements in the lower plane; and
generating, via respective ones of the plurality of laser diode elements, at least one laser beam that impinges upon the construction plane to produce the at least one three-dimensional object by successive, selective layer-by-layer solidification of the individual construction material layers of the solidifiable construction material, wherein the specific spatial offset allows the at least one laser beam emitted by the corresponding portion of the plurality of laser diode elements in the upper plane to respectively pass through the corresponding space defined between respective ones of the corresponding portion of the plurality of laser diode elements in the lower plane directly onto the construction plane.
