In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprises 10-70 wt. % cyclopolymerizable monomer, based on the total weight of the ink. The cyclopolymerizable monomer comprises a first ethenyl or ethynyl moiety and a second ethenyl or ethynyl moiety. Additionally, the α-carbon of the first ethenyl or ethynyl moiety and the α-carbon of the second ethenyl or ethynyl moiety have a 1,5-, 1,6-, 1,7-, or 1,8-relationship.
