A device for producing products having individual geometries, comprising a substrate carrier device, a material application device for applying material, and a control device coupled to the material application device. The material application device is coupled to an input interface for signaling and for selection of a first or a second application mode, the control device and the application device being designed in a first application mode to produce a three-dimensional product on the surface of a substrate plate by way of an additive production method. The control device and the application device are further designed such that in a second mode of application, one or more colors are applied to predetermined regions of a print substrate material connected to the substrate carrier device to produce a monochrome or polychrome print.

Device for the generative manufacturing of three-dimensional components

The invention relates to a device for producing products having individual geometries, comprising a substrate carrier device, a material application device for applying material, preferably above the substrate carrier device, which material application device can be moved relative to the substrate carrier device, and a control device which is coupled to the material application device for signaling. According to the invention, the material application device is coupled to an input interface for signaling and for selection of a first or a second application mode, the control device and the application device being designed such as to produce, in the first application mode, a three-dimensional product on the surface of a substrate plate by way of an additive production method, said substrate plate being connected to the substrate carrier device. According to the additive production method, a curable material is applied in consecutive layers, one or more predetermined regions are selectively cured after or during each application of a layer, the predetermined regions being bonded to one or more regions of the underlying layer. The predetermined region(s) is/are predetermined by a cross-section geometry of the product in the respective layer and is/are stored in the control device, and the curable material is applied in a plurality of consecutive layers to produce the three-dimensional product. The control device and the application device are further designed such that in the second mode of application one or more colors are applied to predetermined regions of a print substrate material connected to the substrate carrier device to produce a monochrome or polychrome print.

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.

Particle size influencing layer-by-layer manufacturing method

The invention relates to a process for producing products having a specific geometry, in particular dental prostheses or auxiliary dental parts, comprising the steps of producing a plurality of products on the surface of a substrate plate by selective curing, in particular by selective sintering or melting, wherein the material is applied in successive layers, one or a plurality of predetermined regions are selectively cured by means of high-energy radiation and joined to one or a plurality of regions of the subjacent layer after each application of a layer, wherein the predetermined regions are predetermined according to a cross-sectional geometry of the product in the respective layer. According to the invention, a substrate plate is provided which is subdivided into a first substrate plate segment and at least one further substrate plate segment that are detachably joined to each other or to a base carrier, a first product is produced on the first substrate plate segment by applying successive layers of material onto the first substrate plate segment and selectively curing predetermined regions of each applied layer of material after it has been applied, and at least one further product is produced on the at least one further substrate plate segment by applying successive layers of material onto the further substrate plate segment and selectively curing predetermined regions of each applied layer of material after it has been applied. The invention also relates to an apparatus for conducting such a process.

A method and apparatus used to produce control data for building up a product layer by layer using freeform sintering and/or melting with a high energy beam. The correspondingly controlled apparatus for production of the products is further disclosed. The high energy beam is applied under the guidance of the control data set. Before beginning the freeform sintering and/or freeform melting, a compensation data set and/or a compensation function to compensate for manufacturing related effects caused by the sintering and/or melting is determined. The control data set is based upon a product target geometry data set and the compensation data set and/or the compensation function.
