Abstract

The present invention relates to the use of free-radically curable compositions, comprising chain-like and/or cyclic and/or cage-type polysiloxanes substituted by free-radically polymerizable groups and having at least 3 silicon atoms and/or mixed forms thereof, disiloxanes substituted by free-radically polymerizable groups, optionally one, two, three or more free-radically curable monomers having no silicon atom, fillers, initiators and/or catalysts for free-radical polymerization, and also further customary additives, in additive manufacturing methods, preferably in stereolithography (SL) and digital light processing (DLP). The present invention further relates to the use of the cured free-radically curable compositions, preferably for production of dental products.
