  • Patent number: 9764513
    Abstract: The invention relates to a method for the construction of a shaped body from photopolymerizable material by using lithography-based generative production, in which a layer of liquid photopolymerizable material is defined on a production platform, and is polymerized in an exposure region having a predetermined contour, a further layer of photopolymerizable material is defined, the layer defined last is polymerized in an exposure region having a predetermined contour for the layer defined last, and the latter two steps are repeated until a shaped body having a predetermined shape has been formed by the sequence of cured layers with contours predetermined layer by layer, each exposure in an exposure region having a predetermined contour being carried out by controlled activation of individual exposure elements in a two-dimensional array of exposure elements, each exposure element being assigned an image element, wherein the exposure of the exposure region is carried out by a common light source and by a two-dime

  • Patent number: 9662188
    Abstract: The invention relates to a method for producing a dental restoration part, in which method, geometrical data, in particular data with respect to spatial dimensions, position and/or volume of the restoration part, are determined and stored in order to form a virtual restoration part. In a further process step, the virtual restoration part is provided for the tooth (10) to be replaced by using data of the tooth (10) to be replaced, a neighboring tooth (60) and/or a tooth stump, and said data is stored as color data and is used for the computer-assisted production of the virtual restoration part.

  • Publication number: 20160059495
    Abstract: The invention relates to a process for the layered construction of a shaped body by means of a 3D inkjet printing process with a piezo printhead (2) with several nozzles (6), to each of which a piezo element (8) is allocated which can act on the associated nozzle, in order to discharge ink from it. The piezo printhead (2) is moved, controlled by a control unit, over a construction area, the piezo elements are actuated individually for the locally selective application of filled ink, in order to apply a layer with a contour predetermined by the control unit. The applied layer is allowed to cure and the desired shaped body is constructed by successive application of layers, each with a predetermined contour.

  • Patent number: 9228782
    Abstract: The invention concerns a microwave oven (10) for the heat treatment of ceramic components, in particular of dental ceramic components (12). It is equipped with a susceptor (14) which is positioned in the swell or in the area between a source of microwaves and the component. The susceptor (14) is made of highly pure silicon carbide of hexagonal, rhombohedral or cubic crystal structure, which has in particular a 2H, 4H, 6H or 3C crystal structure.

  • Publication number: 20120308837
    Abstract: Process for the generative preparation of a shaped body in which (a) ceramic slips are applied in layers to a support and cured, (b) a further layer is applied to the cured layer from step (a) and cured, (c) step (b) is repeated until a body with the desired geometric shape is obtained, (d) the body is then subjected to a chemical treatment or a heat treatment to remove the binding agent (debindering), and (e) the body from step (d) is sintered, wherein at least two differently composed ceramic slips are used in steps (a) and (b) for the preparation of the layers.
