Radiation curable composition for use in rapid prototyping or rapid manufacturing processes

摘要

The invention relates to a polymerizable, radiation-curable, in particular UV / Vis-, UV- or Vis-curable composition comprising (i) monomers, the monomers comprising (a.1) at least one of 1,3,5-Tris (co -hydroxyalkyl) isocyanurate-derived triacrylate, where the hydroxyalkyl radical comprises 1 to 8 carbon atoms and can be linear, branched and / or cyclic, and (a.2) at least one di-functional monomer which is not a urethane (meth) acrylate and (ii) at least one further component which comprises at least one photoinitiator for the UV and / or Vis range or a photoinitiator system for the UV and / or Vis range. The invention furthermore relates to a blank in the form of a three-dimensional molded body of a polymerized composition, in particular a radiation-cured composition for the production of dental prosthetic parts, orthopedic appliances or dental pre-forms, and also the use of the composition for producing dental prosthetic parts, orthopedic appliances or dental pre-forms -Forms in a rapid prototyping or in a rapid manufacturing or rapid tooling process.
