Claim 22:
23. A non-transitory machine readable medium comprising data representing a three-dimensional model of an orthodontic article, when accessed by one or more processors interfacing with a 3D printer, causes the 3D printer to create an orthodontic article comprising a reaction product of a photopolymerizable composition comprising a blend of:
30-65 parts by weight of monofunctional (meth)acrylate monomer(s) per 100 parts of the total polymerizable composition, wherein a cured homopolymer of at least one monofunctional (meth)acrylate monomer has a Tg of 30° C. or greater; and
at least one urethane (meth)acrylate comprising polymerized units of an aliphatic polycarbonate diol, wherein the at least one urethane (meth)acrylate comprises a reaction product of at least one of the following:
i) an aliphatic polycarbonate diol, a diisocyanate, a diol (meth)acrylate, and a hydroxy functional (meth)acrylate;
ii) an aliphatic polycarbonate diol and an isocyanate functional (meth)acrylate;
iii) an aliphatic polycarbonate diol, a diisocyanate, and an isocyanate functional (meth)acrylate; or
iv) an aliphatic polycarbonate diol, a diisocyanate, a diol (meth)acrylate, and an isocyanate functional (meth)acrylate.
