A build plate for a three-dimensional printer includes a rigid, optically transparent, gas-permeable planar base having an upper surface and an opposing lower surface; a gas permeable adhesive layer on the base upper surface; and a flexible, optically transparent, gas-permeable sheet having upper and lower surfaces, the upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface positioned on the adhesive layer opposite the base.

A build plate assembly for a three-dimensional printer includes: a lighting panel having individually addressable pixels configured to selectively emit light and/or transmit light from illumination below the pixels to a top surface top surface of the lighting panel; a rigid, optically transparent, gas-impermeable planar screen or base having an upper surface having an uneven surface topology and a lower surface that is affixed to the top surface of the lighting panel; and a flexible, optically transparent, gas-permeable sheet having upper and lower surfaces, the upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface positioned opposite the base, wherein the build plate is configured to permit gas flow to the build surface.

A method of forming a three-dimensional object includes providing a carrier and an optically transparent member having a build surface. The carrier and the build surface define a build region therebetween. The method further includes 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; applying a reduced pressure and/or polymer inhibitor-enriched gas to the polymerizable liquid through the optically transparent member to thereby reduce a gas content of the polymerizable liquid; and continuously or intermittently advancing (e.g., sequentially or concurrently with said irradiating step) said carrier away from said build surface to form said three-dimensional object from said solid polymer.
