摘要:
A polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object of polyurethane, polyurea, or a copolymer thereof, is described. The resin includes at least one of (i) a blocked or reactive blocked prepolymer, (ii) a blocked or reactive blocked diisocyanate, or (iii) a blocked or reactive blocked diisocyanate chain extender.
