Abstract

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.

Abstract

The invention relates to a method for manufacturing layer by layer a product (10), said method comprising the following steps: applying a layer of a curable material, whereby process parameters, such as layer thickness, layer material, can be adjusted, selectively curing predetermined areas of the applied layer (11) in accordance with the geometrical data of the product, whereby process parameters, such as energy form and energy input, can be adjusted, and repeating these steps until the geometry of the product as a cured material is completed, and finally removing the non-cured material. Known methods have the disadvantage that they offer no variability with respect to the local properties of the product. The invention remedies this disadvantage by modifying at least one process parameter during manufacture in order to influence the particle size in a first area of the product compared to a second area of the product.

Abstract

The invention relates to a method, which is used to produce sets of control data for the production of metallic and/or non-metallic products 2, 21 by free-form sintering and/or melting by means of a high-energy beam (8), in particular a laser beam or electron beam, whereby a product 2, 21 is built up, layer by layer 12 to 15, 20, 22, out of a material 6 that is to be spread out in layers, by means of said beam 8, which is guided with the help of a control data set, whereby the method comprises the steps of loading 23 a product target geometry data set that represents the target geometry of the product to be produced and of generating 25 the control data set on the basis of the product target geometry data set. To improve the dimensional accuracy, this method comprises the additional steps of determining 24 a compensation data set and/or a compensation function to compensate for manufacturing-related effects caused by the sintering and/or melting and of combining 25 the compensation data set with and/or applying the compensation function to the product target geometry data set to generate the control data set. The invention further relates to a corresponding device (11) to carry out said type of method as well as a correspondingly controlled apparatus (1) for production of said type of products 2, 21.
