20090176007 | Particle Size Influencing Layer-By-Layer Manufacturing Method - 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. | 07-09-2009 |
20100021865 | METHOD FOR MANUFACTURING IMPLANT ABUTMENTS FOR DENTAL IMPLANTS, AND AN IMPLANT ABUTMENT FOR A DENTAL IMPLANT - The invention relates to a method for manufacturing implant abutments | 01-28-2010 |
20110049739 | APPARATUS AND PROCESS FOR CONTINUOUS GENERATIVE PRODUCTION - The invention concerns a process for producing products of individual geometry, in particular dental prostheses or dental auxiliary parts, comprising the steps of producing a plurality of products on the surface of a substrate plate by means of selective hardening, in particular by means of selective sintering or melting, in which the material is applied in successive layers, after each layer application one or more predetermined regions of the applied layer is selectively hardened by means of an energy-rich radiation and connected to one or more regions of the subjacent layer, wherein the predetermined regions are predetermined on the basis of a cross-sectional geometry of the product in the respective layer. According to the invention the successive layers are applied in layer planes oriented inclinedly relative to the surface of the substrate plate. The invention further concerns an apparatus for carrying out such a process. | 03-03-2011 |
