The invention relates to a method for producing a three-dimensional object (2), comprising the steps: - specifying reference-object information which describes data of a reference object, in particular geometrically structural data, and at least one piece of boundary condition information which describes at least one boundary condition, in particular a geometrically structural boundary condition of the object to be produced (2), - determining load information which describes at least one load value in a specific load situation inside the reference object described by the reference-object information, - determining load regions having load values that deviate from a reference-load value inside the reference object described by the reference-object information, on the basis of the load information, - determining object information which describes geometrically structural data of the object (2) to be produced, on the basis of the load information and of the boundary condition information, - producing the three-dimensional object (2) to be produced, on the basis of the object information, at least those load regions of the three-dimensional object (2) to be produced which have load values that deviate from the reference load value being additively manufactured using the successive selective fusing in layers of a fusible construction material (3).
