摘要: Provided herein according to some embodiments is a polymerizable liquid useful for the production of an energy absorbing three-dimensional object comprising polyurethane, polyurea, or a copolymer thereof by additive manufacturing. The polymerizable liquid may include components having soft segments (e.g., polyol/polyamine midblocks, chain extenders) of different number average molecular weights.

摘要: Provided according to some embodiments is a polymerizable liquid useful for the production of a three-dimensional object comprised of polyurethane, polyurea, or a copolymer thereof by additive manufacturing, the polymerizable liquid comprising a mixture of: (a) a first blocked or reactive blocked prepolymer comprising a compound of the formula X(A) n , where X is a hydrocarbyl group, n is at least 3, and each A is an independently selected substituent of Formula I: (I) where R is a hydrocarbyl group, R' is O or NH, and Z is a blocking group; (b) a polyol and/or polyamine chain extender; (c) optionally a reactive diluent; and (d) a photoinitiator. A method of use of the polymerizable liquid to make a three-dimensional object by additive manufacturing and prepolymer compounds useful for the same are also provided.
