Abstract
In one aspect, inks for use with a three-dimensional printing system are described herein. In some embodiments, an ink described herein comprises 10-60 wt. % oligomeric curable material; 30-80 wt. % monomeric curable material; and 10-35 wt. % self-curable light-sensitive oligomer, based on the total weight of the ink. Moreover, in some cases, the ink is free or substantially free of non-curable photoinitiator. For example, in some instances, the ink further comprises less than 0.1 wt. % or less than 0.05 wt. % non-curable photoinitiator, based on the total weight of the ink.
