Abstract

Polymerizable compositions suitable for use for 3D printed (e.g. orthodontic) articles, especially orthodontic alignment trays, are described. The polymerizable composition comprises a) 30-70 parts by weight of (meth)acrylate monomer(s); and b) urethane (meth)acrylate polymer; wherein the reaction product comprises at least 1 wt. % polymerized units of a multifunctional compound comprising pendent cyclic moieties. The orthodontic article comprises the reaction product of a polymerizable composition as described herein. The urethane (meth)acrylate polymer typically comprises polymerized units of a multifunctional compound comprising pendent cyclic moieties and/or at least one (meth)acrylate monomer comprises polymerized units of a multifunctional compound comprising pendent cyclic moieties. Also described are methods of making an article, non-transitory machine-readable medium comprising data representing a three-dimensional model of an article, and systems.
