Abstract:
In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprises 20-60 wt. % oligomeric curable material; 10-50 wt. % cyclocarbonate (meth)acrylate monomer; and 0.1-5 wt. % photoinitiator, based on the total weight of the ink. Additionally, in some cases, the ink further comprises one or more additional curable materials differing from the oligomeric curable material and the cyclocarbonate (meth)acrylate monomer. An ink described herein, in some embodiments, also comprises one or more additional component that are non-curable.
