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, said optically transparent member comprising a plurality of channels;
(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 the first component;
(c) irradiating said build region with light through said optically transparent member to form a solid polymer scaffold from the first component and 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, with said intermediate containing said second solidifiable component carried in the scaffold in unsolidified or uncured form;
(d) concurrently with or subsequent to said irradiating step, feeding a polymerization inhibitor through said plurality of channels to said build surface to facilitate formation of a release layer on said build surface; and
(e) subsequent to the irradiating step, solidifying and/or curing the second solidifiable component to form from said three-dimensional intermediate said three-dimensional object,
wherein said build surface comprises a fluoropolymer film, and
wherein said solidifying and/or curing step (e) is carried out by:
(i) heating or microwave irradiating said second solidifiable component;
(ii) irradiating said second solidifiable component with light at a wavelength different from that of the light in said irradiating step (c);
(iii) contacting said second solidifiable component to water; or
(iv) contacting said second solidifiable component to a catalyst.
