摘要： Provided herein is a method of forming a three-dimensional object in which the polymerizable liquid includes a mixture of (i) a light polymerizable first component, and (ii) a heat polymerizable second component; the heat polymerizable second component comprising (i) a first blocked reactive constituent that is blocked with a volatile blocking group, and optionally (ii) a curative. Upon heating a formed three-dimensional intermediate sufficiently, the volatile blocking group is cleaved and vaporizes out of the three-dimensional intermediate, to form the three-dimensional object. Also provided is a three-dimensional object produced by the method. Further provided is a polymerizable liquid composition useful for carrying out the method, and prepolymers and monomers useful for the polymerizable liquid composition.

摘要： Provided herein is an additive manufacturing method of making a three-dimensional object comprising polyurea, comprising: (a) dispensing a one part (1K) dual cure resin into a stereolithography apparatus, the resin comprising or consisting essentially of a photoinitiator, a reactive blocked polyisocyanate, and optionally a polyepoxide, the reactive blocked polyisocyanate comprising the reaction product of a polyisocyanate and an amine or hydroxyl (meth)acrylate or (meth)acrylamide monomer blocking agent; (b) additively manufacturing from said resin an intermediate object comprising the light polymerization product of said reactive blocked polyisocyanate; (c) optionally cleaning said intermediate object; and (d) reacting said polymerization product in said intermediate with water to generate polyamine in situ that sequentially reacts with the remainder of the polymerization product to form urea linkages and hereby produce a three-dimensional object comprising polyurea. One part (1K) dual cure resins useful for the method are also provided.
