    摘要: 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 (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, said optically transparent member comprising a flexible layer having upper and lower opposing sides, wherein the flexible layer upper side defines the build region, the method further comprising forming a region of reduced pressure adjacent the flexible layer lower side.
