Abstract: A method of forming a three-dimensional object, the object having a wall and an internal cavity, with the wall having an upper portion and a lower portion, is carried out by: providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid; continuously or intermittently irradiating the build region with light through the optically transparent member to form a solid polymer from 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, with the method further including the step of forming a breathing orifice in the wall upper portion (e.g., adjacent the carrier) while forming said three-dimensional object. Apparatus for carrying out the method is also described.

Abstract: 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.

Abstract: 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.

Abstract: A method of forming a three-dimensional object including a continuous sheet of material includes: (a) providing at least one drive roller and a build plate, with the build plate including an optically transparent member, with the optically transparent member including a build surface, and with the build surface at least partially defining a build region and the at least one drive roller adjacent the build region; (b) filling the build region with a polymerizable liquid; (c) irradiating the build region with light through the optically transparent member to form a solid polymer from the polymerizable liquid; and (d) rotating the at least one drive roller to form the three-dimensional object from the solid polymer and/or to advance (or draw) the continuous sheet of material away from the build region.
