摘要:
The invention concerns a process for the layerwise production of a product comprising the steps of applying a layer of a hardenable material, wherein for example the process parameters of layer thickness and layer material are adjustable, selectively hardening predetermined regions of the applied layer on the basis of the geometrical data of the product, wherein for example the process parameters for the nature and level of the energy input are adjustable, repeating those steps until the geometry of the product has been produced in the form of hardened material, and finally removing the non-hardened material. Known processes suffer from the disadvantage that they do not afford variability in regard to the local properties of the product. The invention remedies that disadvantage insofar as at least one process parameter is altered during the production procedure in order to influence the grain size in a first region of the product in relation to a second region of the product.
