| 20080287564 | Low-Viscosity, Radiation-Curable Formulation for Producing Adaptive Earpieces - The invention relates to a biocompatible, low-viscosity, radiation-curable formulation for producing medical products, in particular adaptive ear pieces, otoplastic parts, shells or ear parts, by means of PNP methods or stereolithographic methods. Said formulation comprises: a) 15-60 wt. % of a monomeric or oligomeric dimethacrylate based on bisphenol A or bisphenol F; b) 0-50 wt. % one or more monomeric or oligomeric urethane (meth)acrylates with a functionality n<4, a viscosity <30 Pa s and a molecular weight <3500; c) 2-25 wt. % of a monomeric, aliphatic or cycloaliphatic dimethacrylate with a viscosity <3 Pa s; d) 2-35 wt. % of an iminooxadiazone dion derivative, characterised by 3 methacrylate and/or acrylate functions; 0-15 wt. % one or more monofunctional methacrylates; f) 0.5-6 wt. % of a photo initiator or a combination of photo initiators, whose absorption lies in the wavelength range of the laser beam that is used or the irradiation source; g) 0-0.5 wt. % one or more anaerobic inhibitors; h) 0-40 wt. % fillers with a particle size <25 μm; i) 0-5 wt. % colorants; j) 0-5 wt. % conventional additives such as UV stabilisers or process additives, whereby the sum of the fraction of the components a) to j) totals 100 wt. %. | 11-20-2008 |
| 20100310698 | DEVICE AND METHOD FOR THE GENERATIVE PRODUCTION OF THREE-DIMENSIONAL OBJECTS ON THE BASIS OF A MULTIPHASE SYSTEM - The invention relates to a device and to a method for the production of a three-dimensional object by the consecutive layered bonding of a material that can be bonded by means of electromagnetic radiation, wherein in the so-called vat an at least n-phase system, where n>2, is present, of which at least one phase comprises the building material and at least one other a phase that cannot be mixed with the building material. | 12-09-2010 |
| 20100316972 | METHOD FOR THE GENERATIVE PRODUCTION OF INDIVIDUAL DENTAL PREFORMED PARTS FOR ARTICULATORS - Method for the production of a denture comprising the following steps:—collection of the biometric data of a patient, namely, the toothed or untoothed mandible and maxilla, the sizing of the jaws, the spatial position thereof relative to the skull, the condyle inclination and the movement of the mandible, and the recording of the mandible movement;—implementation of the data in a virtual articulator which is made available in the main memory of the data processing equipment;—CAD construction of the individual articulator preformed parts and dental molded bodies based on the collected patient data;—production of the individual articulator molded bodies and dental molded bodies by means of a generative manufacturing process based on the recorded biometric data;—incorporation of the individual articulator preformed parts and/or dental molded bodies into a standardized articulator housing, or complete generative manufacture of the articulator with individualized molded bodies. | 12-16-2010 |
