A process for producing an object from a precursor comprises the steps of: I) depositing a free-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 free-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 free-radically crosslinked resin at least in step II) is effected by exposure and/or irradiation of a selected region of a free-radically crosslinkable resin corresponding to the respectively selected cross section of the object and wherein the free-radically crosslinkable resin has a viscosity (23 C., DIN EN ISO 2884-1) of 5 mPas to 100000 mPas. In the process the free-radically crosslinkable resin comprises a curable component in which NCO groups and olefinic CC double bonds are present, wherein in the curable component the molar ratio of NCO groups to olefinic CC double bonds is in a range from 1:5 to 5:1.

In the process, after step III) step IV) is further performed: IV) treating the precursor obtained after step III) under conditions sufficient to at least partially trimerize to isocyanurate groups NCO groups present in the free-radically crosslinked resin of the obtained precursor to obtain the object.
