(a) providing a carrier and a build plate, wherein the build plate comprises a semipermeable member, the semipermeable member comprises a build surface, the build surface and carrier form a build area therebetween, and the build surface comprises a semi- In fluid communication with a source of polymerization inhibitor; (b) filling the build region with a polymerizable liquid, the polymerizable liquid contacting the build surface; (c) forming or maintaining a liquid film separation layer comprising a polymerizable liquid formed between the solid polymerized region and the build surface while irradiating the build region through the build plate to create a solid polymerized region in the build region Wherein polymerization of the liquid film is inhibited by a polymerization inhibitor; And (d) advancing the carrier away from the build surface of the build plate with the polymerized area attached thereto to create a subsequent build area between the overlap region and the build surface, There is provided a method of forming a three-dimensional object by filling a region with a polymerizable liquid. An apparatus for carrying out the method is also described. |
