| 20110316178 | Method And Apparatus For Making Products By Sintering And/Or Melting - The invention relates to a method for making metallic and/or non-metallic products | 12-29-2011 |
| 20110180971 | Method for the Production of Heavily Inclined Surfaces in Layers - The invention relates to a method for manufacturing a product in layers, said method comprising the following steps: (a) applying a layer of a curable material, (b) selectively curing predetermined zones of the applied layer on the basis of geometrical data of the product, (c) repeating steps (a) and (b) until the geometry of the product has been created in the form of cured material and (d) removing the uncured material. According to the invention, a finish allowance, for example one with a wedge-shaped cross-section, is applied in steps (a) and (b), in one, two or more product sections in which an angle (α) between an axis perpendicular to the layers and at least one surface section of a contour of the product exceeds a predetermined value, to said surface section in such a way that the angle (β) between the axis perpendicular to the layers and the external surface in said product section does not exceed said predetermined value. | 07-28-2011 |
| 20110170977 | Dual Production Method and Dual Production Device for the Small-Scale Manufacture of Products - The invention relates to a method for manufacturing products by applying material at least partially in layers to form a structure, in particular by selective laser melting (SLM), said method comprising the steps of: (a) providing a base plate, (b) applying a layer of a curable material, (c) selectively curing predetermined zones of the applied layer on the basis of geometrical data of the product, (d) repeating steps (b) and (c) until the geometry of a first partial volume of the product has been created in the form of a cured material and (e) removing the uncured material. According to the invention, a reference mark is provided, the unit formed by the base plate and the first volume zones is clamped into a specific position by means of the reference mark and the respective second partial volume of the respective product is cut from the base plate, preferably by machining, in particular CNC milling. | 07-14-2011 |
| 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 |
| 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 |
