A process for producing an object from a precursor, comprising the steps of: I) depositing a radically crosslinked resin atop a carrier to obtain a ply of a construction material joined to the carrier which corresponds to a first selected cross section of the precursor; II) depositing a radically crosslinked resin atop a previously applied ply of the construction material to obtain a further ply of the construction material which corresponds to a further selected cross section of the precursor and which is joined to the previously applied ply; III) repeating step II) until the precursor is formed; wherein the depositing of a radically crosslinked resin at least in step II) is effected by introducing energy to a selected region of a radically crosslinkable resin corresponding to the respectively selected cross section of the object, and wherein the radically crosslinkable resin has a viscosity (23°C, DIN EN ISO 2884-1) of ≥ 5 mPas to ≤ 100 000 mPas, characterized in that the radically crosslinkable resin comprises a curable component, in which NCO groups 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 such that deblocking of the NCO group is not followed by liberation of the blocking agent as a free molecule or as a part of other molecules or moieties and in that step III) is followed by a further step IV): IV) treating the precursor obtained after step III) under conditions sufficient for at least partially deblocking NCO groups present in the radically crosslinked resin of the obtained precursor and reacting the thus obtained functional groups with compounds having at least two Zerewitinoff-active H atoms to obtain the object. I) depositing a radically crosslinked resin atop a carrier to obtain a ply of a construction material joined to the carrier which corresponds to a first selected cross section of the precursor; II) depositing a radically crosslinked resin atop a previously applied ply of the construction material to obtain a further ply of the construction material which corresponds to a further selected cross section of the precursor and which is joined to the previously applied ply; III) repeating step II) until the precursor is formed; wherein the depositing of a radically crosslinked resin at least in step II) is effected by introducing energy to a selected region of a radically crosslinkable resin corresponding to the respectively selected cross section of the object, and wherein the radically crosslinkable resin has a viscosity (23°C, DIN EN ISO 2884-1) of ≥ 5 mPas to ≤ 100 000 mPas, characterized in that the radically crosslinkable resin comprises a curable component, in which NCO groups 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 such that deblocking of the NCO group is not followed by liberation of the blocking agent as a free molecule or as a part of other molecules or moieties and in that step III) is followed by a further step IV): wherein the depositing of a radically crosslinked resin at least in step II) is effected by introducing energy to a selected region of a radically crosslinkable resin corresponding to the respectively selected cross section of the object, and wherein the radically crosslinkable resin has a viscosity (23°C, DIN EN ISO 2884-1) of ≥ 5 mPas to ≤ 100 000 mPas, characterized in that the radically crosslinkable resin comprises a curable component, in which NCO groups 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 such that deblocking of the NCO group is not followed by liberation of the blocking agent as a free molecule or as a part of other molecules or moieties and in that step III) is followed by a further step IV): IV) treating the precursor obtained after step III) under conditions sufficient for at least partially deblocking NCO groups present in the radically crosslinked resin of the obtained precursor and reacting the thus obtained functional groups with compounds having at least two Zerewitinoff-active H atoms to obtain the object.
