Abstract
In one aspect, inks for use with a three-dimensional printing system are described herein. In some embodiments, an ink described herein comprises a thiol monomer component and an ene monomer component. Moreover, in some cases, an ink described herein further comprises an additional (meth)acrylate monomer component differing from the ene monomer component. In some such cases, the additional (meth)acrylate monomer component can be polymerized separately from the thiol and ene monomers of the ink.
