Claim 0:
1. A method of forming a three-dimensional object comprised of a silicone polymer, said method comprising:
(a) providing a silicone dual cure resin; wherein said silicone dual cure resin comprises:
(i) a light polymerizable first reactant;
(ii) a photoinitiator;
(iii) a second reactant comprising at least one siloxane linkage, and
(iv) optionally a catalyst;

wherein said light polymerizable first reactant optionally contains at least one siloxane linkage;
(b) forming a solid polymer scaffold by irradiating said light polymerizable first reactant with patterned actinic radiation or light to form a three-dimensional intermediate from said resin, where said intermediate has the shape of, or a shape to be imparted to, said three-dimensional object, and wherein said second reactant is carried within the polymer scaffold in unsoldified form, whereby said three-dimensional intermediate is fabricated in a layer-by-layer or layerless manner through multiple exposures of the patterned actinic radiation or light; then
(c) further reacting said three-dimensional intermediate, said further reacting sufficient to form said three-dimensional object comprised of a silicone polymer from said three-dimensional intermediate,
wherein said further reacting in step (c) is carried out by a method comprising contacting said intermediate to moisture.
