BIOCOMPATIBLE RADIATION-CURABLE FORMULATION FOR THE GENERATIVE PRODUCTION OF MEDICAL PRODUCTS, PARTICULARLY ADAPTIVE EAR PIECES AND DENTAL MOULDINGS, BY MEANS OF IMAGE PROJECTION SYSTEMS

摘要

The invention relates to a radiation-curable, biocompatible formulation comprising: a) at least one or more urethane poly(meth)acrylates, b) at least one or more (poly)(meth)acrylates, or a combination thereof, c) at least one initiator usable for the relevant radiation range, d) at least one or more or a combination of anaerobic and/or aerobic stabilizers, e) and in a particular, clear transparent embodiment, advantageously made of at least 0.1m% surface-modified nanoparticles, f) 0-40m% of fillers, g) 0-5m% of color pigments, h) 0.5m% of typical additives such as UV stabilizers or flow-control additives, wherein the proportion of components a) through h) is 100m% altogether, and the entire formulation lies within the so-called “wetting envelope' of the pre-hardened layer, present in the green-flex mode, of said formulation and has a viscosity of 10 Pas at 23 °C.
