1. An apparatus for forming a three-dimensional object from a polymerizable liquid, comprising:
(a) a support;
(b) a carrier operatively associated with said support on which carrier said three-dimensional object is formed;
(c) an optically transparent member having a build surface, with said build surface and said carrier defining a build region therebetween; and
(d) a liquid polymer supply operatively associated with said build surface and configured to supply liquid polymer into said build region for solidification polymerization,
wherein said optically transparent member comprises a patterned bottom including at least one recess, wherein the at least one recess is filled with optically transparent liquid.
