Claim 7:
8. The process as claimed in claim 7, wherein the depositing in step A) comprises:
I) depositing the free-radically crosslinked resin on a carrier to obtain a ply of build material joined to the carrier that corresponds to a first selected cross section of the precursor;
II) depositing the free-radically crosslinked resin onto the ply of build material to obtain a further ply of build material that corresponds to a further selected cross section of the precursor that is joined to the previously applied ply;
III) repeating step II) until the precursor is formed;
wherein depositing the free-radically crosslinked resin at least in step II) further comprises exposure and/or irradiation of a selected region of the free-radically crosslinkable resin corresponding to the respectively selected cross section of the precursor and
the treating in step B) comprises:
IV) treating the precursor obtained in step III) under conditions sufficient for reaction of NCO groups and epoxide groups to form oxazolidinone groups.
