1. A process for producing a cured polymeric product, comprising
providing an additive manufacturing device comprising a source of actinic radiation, an exterior support structure, an interior tank capable of containing a liquid mixture, and an interior support structure,
providing an actinic radiation curable polymeric mixture to the interior tank, wherein the actinic radiation curable polymeric mixture comprises
(a) a polyfunctionalized diene monomer-containing polymer having a formula as follow: [P][F]n where P represents a diene polymer chain, F represents a functional group, n is 2 to about 15, the diene polymer chain includes at least one of isoprene and 1,3-butadiene monomers, and each F is selected from the group consisting of acrylate, methacrylate, cyanoacrylate, epoxide, aziridine, thiopeoxide, and combinations thereof;
(b) optionally a chain extender based upon F or reactive with F;
(c) at least one actinic radiation sensitive photoinitiator;
(d) optionally, a photosensitizer; and
(e) a polyfunctional crosslinker reactive with F,
repeatedly forming upon a support structure a layer from the actinic radiation curable polymeric mixture, wherein the support structure comprises a tire component, and
using actinic radiation to cure each layer,
thereby producing the cured polymeric product.
