METHOD OF MAKING AN OBJECT FROM A PRECURSOR AND USE OF A RESIN WHICH CAN BE RADICALLY CROSSLINKED BY MEANS OF AN ADDITIVE PRODUCTION METHOD

The invention relates to a method for producing an object from a precursor, comprising the steps: I) depositing a radically cross-linked resin on a carrier so that a layer of a construction material connected to the carrier is obtained, said layer corresponding to a first selected cross-section of the precursor; II) depositing a radically cross-linked resin on a previously applied layer of the construction material so that an additional layer of the construction material is obtained, which corresponds to a further selected cross-section of the precursor and which is connected to the previously applied layer; III) repeating step II) until the precursor is formed, wherein, at least in step II), the deposition of a radically cross-linked resin is carried out by allowing energy to act on a selected region of a radically cross-linkable resin, corresponding to the respectively selected cross-section of the object, wherein the radically cross-linkable resin has a viscosity (23° C., DIN EN ISO 2884-1) of =5 mPas to =100000 mPas. The radically cross-linkable resin comprises a curable component, in which NCO groups which are blocked with a blocking agent, compounds having at least two Zerewitinoff-active H atoms and olefinic C═C double bonds are present, wherein the blocking agent is an isocyanate or the blocking agent is selected in such a manner that, after deblocking of the NCO group, no release of the blocking agent as a free molecule or as a part of other molecules or molecule parts occurs. Following step III), step IV) is carried out: IV) treating the precursor obtained according to step III) under conditions which are sufficient to at least partially deblock NCO groups which are present in the radically cross-linked resin of the obtained precursor, and to react the resulting functional groups with compounds having at least two Zerewitinoff-active H atoms, with the result that the object is obtained.
