Abstract
Provided is a polymerizable liquid (or “resin”) for producing three-dimensional objects by additive manufacturing, which may include one or more of: (a) a polyvinyl siloxane; (b) a polythiol crosslinker; (c) a photoinitiator (e.g., a free radical photoinitiator); (d) optionally, a urethane (meth)acrylate oligomer; (e) optionally, a reactive diluent; (f) optionally, but in some embodiments preferably, a pigment or dye; (g) optionally, but in some embodiments preferably, a reactive or non-reactive filler; and (h) optionally, an odor scavenger.
