PRODUCTION OF MOLDED BODIES FROM AN INORGANIC-ORGANIC HYBRID POLYMER WITH HIGH RESOLUTION USING 3D PRINTING, MOLDED BODIES WITH A HIGH FLEXURAL STRENGTH AND ELASTIC MODULUS, AND THE USE THEREOF FOR DENTAL PURPOSES

The invention relates to a method for producing a shaped body by means of a radiation-induced printing process according to the technique of the one-photon polymerization process, characterized in thatthe shaped body is produced by solidifying a liquid or viscous material which contains a polysiloxane component produced by hydrolytic condensation of one or more monomeric silanes having exclusively two or three hydrolyzable groups and at least one organically polymerizable radical being bonded to the silicon atom via carbon, and contains an initiator and/or catalyst for the radiation-induced polymerization of the organically polymerizable residue, andthe solidification is effected by directing light onto a region of a surface of a substrate, whereby a layer of the material located there is polymerized and thereby solidified, whereupon further layers are successively solidified.Furthermore, the invention relates to a shaped body based on an organically polymerized silica (hetero)polycondensate, which was produced by organic polymerization of the aforementioned polysiloxane component, with superior mechanical properties.
