1. A method of forming a three-dimensional object, comprising:
providing a carrier and an optically transparent member having a build surface, said carrier and said build surface defining a build region therebetween;
filling said build region with a polymerizable liquid,
continuously or intermittently irradiating said build region with light through said optically transparent member to form a solid polymer from said polymerizable liquid,
continuously or intermittently advancing said carrier away from said build surface to form said three-dimensional object from said solid polymer,
wherein said optically transparent member comprises a build plate comprising:
a rigid, optically transparent planar base having an upper surface and an opposing lower surface;
a first gas permeable adhesive layer on the base upper surface; and
a first flexible, optically transparent, gas-permeable sheet on the first gas permeable adhesive layer,
a second gas permeable adhesive layer on the first flexible, optically transparent, gas-permeable sheet; and
a second flexible, optically transparent, gas permeable sheet on the second gas permeable adhesive layer and having upper and lower surfaces, wherein the upper surface of the second flexible, optically transparent, gas-permeable sheet comprises a build surface for forming a three-dimensional object, and the lower surface of the second flexible, optically transparent, gas-permeable sheet is positioned on the second gas permeable adhesive layer, and
wherein said build plate is fixed and stationary in lateral directions.
