Abstract
A polymerizable liquid useful for the production of a three-dimensional object comprised of silicone, or a copolymer thereof, which includes at least one constituent selected from the group consisting of (i) a blocked or reactive blocked siloxane-containing prepolymer, (ii) a blocked or reactive blocked siloxane-containing polyisocyanate, and (iii) a blocked or reactive blocked siloxane-containing polyisocyanate chain extender. Methods of using the same in additive manufacturing processes such as continuous liquid interface production are also described.
