Claim:
1. A method of forming a three-dimensional object, comprising: (a) providing a carrier and an optically transparent member having a build surface, said carrier and said build surface defining a build region therebetween; (b) filling said build region with a polymerizable liquid, said polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component; (c) irradiating said build region with light through said optically transparent member to form a solid polymer scaffold from said first component and also advancing said carrier away from said build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, said three-dimensional object and containing said second solidifiable component carried in said scaffold in unsolidified and/or uncured form; and (d) subsequent to said irradiating step, heating, microwave irradiating, or both heating and microwave irradiating, said second solidifiable component in said three-dimensional intermediate to form said three-dimensional object.
